Integration information

Processor

Intel NUC Board NUC6CAYB has a soldered-down System-on-a-Chip (SoC), which consists of a

quad-core Intel Celeron processor J3455 with up to 10 W TDP.



Integrated Intel HD Graphics 500

Integrated memory controller

Integrated PCH

NOTE

This board has specific requirements for providing power to the processor. Refer to

Section 2.5.1 on page 53 for information on power supply requirements for this board.

Product Description

1.4

System Memory

The board has two 204-pin SO-DIMM sockets and supports the following memory features:



1.35 V DDR3L 1600/1866 MHz SDRAM non-ECC SO-DIMM with gold plated contacts on

Intel Celeron processor J3455



Two memory channels

Unbuffered, single-sided or double-sided SO-DIMMs using 4 Gb or 8 Gb technology

(density)



8 GB maximum total system memory (with 4 Gb or 8 Gb memory technology). Refer to

Section 2.1.1 on page 37 for information on the total amount of addressable memory.

Minimum recommended total system memory: 2048 MB

Serial Presence Detect

Optional 2 GB DDR3L 1600 MHz SO-DIMM pre-installed (included in Intel NUC Kit

NUC6CAYS only)



NOTE

To be fully compliant with all applicable DDR SDRAM memory specifications, the board should

be populated with SO-DIMMs that support the Serial Presence Detect (SPD) data structure.

This allows the BIOS to read the SPD data and program the chipset to accurately configure

memory settings for optimum performance. If non-SPD memory is installed, the BIOS will

attempt to correctly configure the memory settings, but performance and reliability may be

impacted or the SO-DIMMs may not function under the determined frequency.

NOTE

Intel NUC Board NUC6CAYB supports only 4 Gb and 8 Gb memory technologies (also referred

to as “SDRAM density”). Table 4 lists the supported SO-DIMM configurations. Table 5 lists the

SO-DIMM configurations that are not supported.

Video Memory Allocation

Intel^®Dynamic Video Memory Technology (DVMT) is a method for dynamically allocating

system memory for use as graphics memory to balance 2D/3D graphics and system

performance. If your computer is configured to use DVMT, graphics memory is allocated based

on system requirements and application demands (up to the configured maximum amount).

When memory is no longer needed by an application, the dynamically allocated portion of

memory is returned to the operating system for other uses.

1.5.2

High Definition Multimedia Interface* (HDMI*)

The HDMI port supports standard, enhanced, or high definition video, plus multi-channel

digital audio on a single cable. The port is compatible with all ATSC and DVB HDTV standards

and supports eight full range channels at 24-bit/96 kHz audio of lossless audio formats. The

SATA Interface

The SoC provides one SATA port with a theoretical maximum transfer rate of 6.0 Gb/s. A

point-to-point interface is used for host to device connections.

The underlying SATA functionality is transparent to the operating system. The SATA

controller can operate in both legacy and native modes. In legacy mode, standard IDE I/O and

IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI Conventional bus

resource steering is used. Native mode is the preferred mode for configurations using

Windows* operating systems.

1.7.1

AHCI Mode

The board supports AHCI storage mode.

NOTE

In order to use AHCI mode, AHCI must be enabled in the BIOS. Microsoft* Windows* 10 includes

the necessary AHCI drivers without the need to install separate AHCI drivers during the

operating system installation process. However, it is always good practice to update the AHCI

drivers to the latest available by Intel.

Embedded MultiMediaCard (e-MMC) - optional

The board contains a 32 GB Embedded MultiMediaCard (e·MMC) onboard storage module with

Windows 10 Home operating system preinstalled (e-MMC and OS included in Intel NUC Kit

NUC6CAYS only).

Real-Time Clock Subsystem

A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the

computer is not plugged into a wall socket, the battery has an estimated life of three years.

When the computer is plugged in, the standby current from the power supply extends the life

of the battery. The clock is accurate to  13 minutes/year at 25 ºC with 3.3 VSB applied via the

power supply 5 V STBY rail.

NOTE

If the battery and AC power fail, date and time values will be reset and the user will be notified

during the POST.

When the voltage drops below a certain level, the BIOS Setup program settings stored in

CMOS RAM (for example, the date and time) might not be accurate. Replace the battery with

an equivalent one. Figure 1 on page 13 shows the location of the battery.

System States and Power States

Under ACPI, the operating system directs all system and device power state transitions. The

operating system puts devices in and out of low-power states based on user preferences and

knowledge of how devices are being used by applications. Devices that are not being used can

be turned off. The operating system uses information from applications and user settings to

put the system as a whole into a low-power state.

Table 8 lists the power states supported by the board along with the associated system power

targets. See the ACPI specification for a complete description of the various system and power

states.

Product Description

1.13.2.1

Power Input

When resuming from an AC power failure, the computer may return to the power state it was

in before power was interrupted (on or off). The computer’s response can be set using the Last

Power State feature in the BIOS Setup program’s Boot menu.

1.13.2.2

Instantly Available PC Technology

Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM)

sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply

is off, and the front panel LED is amber if dual colored, or off if single colored.) When signaled

by a wake-up device or event, the system quickly returns to its last known wake state. Table 9

on page 32 lists the devices and events that can wake the computer from the S3 state.

The use of Instantly Available PC technology requires operating system support and drivers

for any installed PCI Express add-in card.

1.13.2.3

LAN Wake Capabilities

LAN wake capabilities enable remote wake-up of the computer through a network. The LAN

subsystem monitors network traffic at the Media Independent Interface. Upon detecting a

Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the

computer.

1.13.2.4

Wake from USB

USB bus activity wakes the computer from an ACPI S3, S4, and S5 states.

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB.

1.13.2.5

Technical Reference

2.1

Memory Resources

2.1.1

Addressable Memory

The board utilizes up to 8 GB of addressable system memory. Typically the address space that is

allocated for PCI Conventional bus add-in cards, PCI Express configuration space, BIOS (SPI Flash

device), and chipset overhead resides above the top of DRAM (total system memory). On a

system that has 8 GB of system memory installed, it is not possible to use all of the installed

memory due to system address space being allocated for other system critical functions. These

functions include the following:



BIOS/SPI Flash device (64 Mbit)

Local APIC (19 MB)

Direct Media Interface (40 MB)

PCI Express configuration space (256 MB)

SoC base address registers PCI Express ports (up to 256 MB)

Memory-mapped I/O (I/O fabric) that is dynamically allocated for PCI Express add-in cards

(256 MB)

The board provides the capability to reclaim the physical memory overlapped by the memory

mapped I/O logical address space. The board remaps physical memory from the top of usable

DRAM boundary to the 4 GB boundary to an equivalent sized logical address range located just

above the 4 GB boundary. All installed system memory can be used when there is no overlap of

system addresses.

Thermal Considerations

CAUTION

A chassis with a maximum internal ambient temperature of 58 ^oC at the processor fan inlet is

recommended. If the internal ambient temperature exceeds 58 ^oC, further thermal testing is

required to ensure components do not exceed their maximum case temperature.

CAUTION

Failure to ensure appropriate airflow may result in reduced performance of both the processor

and/or voltage regulator or, in some instances, damage to the board.

All responsibility for determining the adequacy of any thermal or system design remains solely

with the system integrator. Intel makes no warranties or representations that merely following the

instructions presented in this document will result in a system with adequate thermal

performance.

CAUTION

Ensure that the ambient temperature does not exceed the board’s maximum operating

temperature. Failure to do so could cause components to exceed their maximum case

temperature and malfunction. For information about the maximum operating temperature, see

the environmental specifications in Section 2.8.

CAUTION

The processor voltage regulator area (shown in Figure 19) can reach a temperature of up to

97.5 ^oC in an open chassis. Ensure that proper airflow is maintained in the processor voltage

regulator circuit. Failure to do so may result in shorter than expected product lifetime.

Figure 19 shows the locations of the localized high temperature zones.

Figure 19. Localized High Temperature Zones

Technical Reference

Table 27 provides maximum case temperatures for the components that are sensitive to thermal

changes. The operating temperature, current load, or operating frequency could affect case

temperatures. Maximum case temperatures are important when considering proper airflow to

cool the board.

Table 27. Thermal Considerations for Components

Component

Maximum Case Temperature

Processor

For processor case temperature, see processor datasheets and processor

specification updates

To ensure functionality and reliability, the component is specified for proper operation when

Case Temperature is maintained at or below the maximum temperature listed in Table 28. This is

a requirement for sustained power dissipation equal to Thermal Design Power (TDP is specified

as the maximum sustainable power to be dissipated by the components). When the component is

dissipating less than TDP, the case temperature should be below the Maximum Case

Temperature. The surface temperature at the geometric center of the component corresponds to

Case Temperature.

It is important to note that the temperature measurement in the system BIOS is a value reported

by embedded thermal sensors in the components and does not directly correspond to the

Maximum Case Temperature. The upper operating limit when monitoring this thermal sensor is

Tcontrol.

operating temperature specified. It is recommended that the board temperature be at least room temperature

before attempting to power on the board. The operating and non-operating environment must avoid condensing

humidity.

Overview of BIOS Features

3.1

Introduction

The board uses an Intel Visual BIOS that is stored in the Serial Peripheral Interface Flash Memory

(SPI Flash) and can be updated using a disk-based program. The SPI Flash contains the Visual

BIOS Setup program, POST, the PCI auto-configuration utility, LAN EEPROM information, and

Plug and Play support. The initial production BIOSs are identified as AYAPLCEL.86A.

The Visual BIOS Setup program can be used to view and change the BIOS settings for the

computer, and to update the system BIOS. The BIOS Setup program is accessed by pressing the

<F2> key after the Power-On Self-Test (POST) memory test begins and before the operating

system boot begins.

NOTE

The maintenance menu is displayed only when the board is in configuration mode. Section 2.3 on

page 50 shows how to put the board in configuration mode.

3.2

3.3

BIOS Flash Memory Organization

The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 64 Mb (8192 KB) flash

memory device.

System Management BIOS (SMBIOS)

SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in

a managed network.

The main component of SMBIOS is the Management Information Format (MIF) database, which

contains information about the computing system and its components. Using SMBIOS, a system

administrator can obtain the system types, capabilities, operational status, and installation dates

for system components. The MIF database defines the data and provides the method for

accessing this information. The BIOS enables applications such as third-party management

software to use SMBIOS. The BIOS stores and reports the following SMBIOS information:



BIOS data, such as the BIOS revision level

Fixed-system data, such as peripherals, serial numbers, and asset tags

Resource data, such as memory size, cache size, and processor speed

Dynamic data, such as event detection and error logging

Non-Plug and Play operating systems require an additional interface for obtaining the SMBIOS

information. The BIOS supports an SMBIOS table interface for such operating systems. Using

this support, an SMBIOS service-level application running on a non-Plug and Play operating

system can obtain the SMBIOS information. Additional board information can be found in the

BIOS under the Additional Information header under the Main BIOS page.

3.4

Legacy USB Support

Legacy USB support enables USB devices to be used even when the operating system’s USB

drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and

to install an operating system that supports USB. However, this requires the addition of USB 3.0

drivers to the operating system image prior to beginning installation. By default, Legacy USB

support is set to Enabled.

Legacy USB support operates as follows:

1. When you apply power to the computer, legacy support is disabled.

2. POST begins.

3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and

configure the BIOS Setup program and the maintenance menu.

4. POST completes.

5. The operating system loads. While the operating system is loading, USB keyboards and mice

are recognized and may be used to configure the operating system. (Keyboards and mice are

not recognized during this period if Legacy USB support was set to Disabled in the BIOS

Setup program.)

6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are

recognized by the operating system, and Legacy USB support from the BIOS is no longer

used. This requires the operating system to have USB 3.0 driver support in order to recognize

devices attached to any of the NUC6AYB’s external USB ports.

To install an operating system that supports USB, verify that Legacy USB support in the BIOS

Setup program is set to Enabled and follow the operating system’s installation instructions.

3.5

BIOS Updates

The BIOS can be updated using either of the following utilities, which are available on the Intel

World Wide Web site:



Intel^®Express BIOS Update utility, which enables automated updating while in the Windows

environment. Using this utility, the BIOS can be updated from a file on a hard disk, a USB

drive (a flash drive or a USB hard drive), or a CD-ROM, or from the file location on the Web.

Intel^®Flash Memory Update Utility, which requires booting from DOS. Using this utility, the

BIOS can be updated from a file on a hard disk, a USB drive (a flash drive or a USB hard drive),

or a CD-ROM.

Intel F7 switch during POST allows a user to select where the BIOS .bio file is located and

perform the update from that location/device. Similar to performing a BIOS Recovery without

removing the BIOS configuration jumper.

Intel Visual BIOS allows the user to select the BIOS .bio file from the internet, USB device,

hard disk drive, or other media.

All utilities verify that the updated BIOS matches the target system to prevent accidentally

installing an incompatible BIOS.

BIOS Recovery

It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs, the

BIOS could be damaged. Table 30 lists the drives and media types that can and cannot be used

for BIOS recovery. The BIOS recovery media does not need to be made bootable.

Boot Options

In the BIOS Setup program, the user can choose to boot from a hard drive, optical drive,

removable drive, or the network. The default setting is for the optical drive to be the first boot

device, the hard drive second, removable drive third, and the network fourth.

NOTE

Optical drives are not supported by the onboard SATA connectors. Optical drives are supported

only via the USB interfaces.

3.7.1

Network Boot

The network can be selected as a boot device. This selection allows booting from the onboard

LAN or a network add-in card with a remote boot ROM installed.

Pressing the <F12> key during POST automatically forces booting from the LAN. To use this key

during POST, the User Access Level in the BIOS Setup program's Security menu must be

set to Full.

3.7.2

Booting Without Attached Devices

For use in embedded applications, the BIOS has been designed so that after passing the POST,

the operating system loader is invoked even if the following devices are not present:



Video adapter

Keyboard

Mouse

3.7.3

Changing the Default Boot Device During POST

Pressing the <F10> key during POST causes a boot device menu to be displayed. This menu

displays the list of available boot devices. Table 31 lists the boot device menu options.

Power Button Menu

The Power Button Menu is accessible via the following sequence:

1. System is in S4/S5 (not G3)

2. User pushes the power button and holds it down

3. The power LED will change to its secondary color to signal the user to release the power

button (approximately 3 seconds); alternately, the system will emit three short beeps from

the PC speaker or headphones, if installed, then stop. Release immediately.

4. User releases the power button before the 4-second shutdown override.

If this boot path is taken, the BIOS will use default settings, ignoring settings in VPD where

possible.

The BIOS will display the following prompt and wait for a keystroke:

[ESC] Normal Boot

[F2]

[F3]

[F4]

[F7]

Intel Visual BIOS

Disable Fast Boot

BIOS Recovery

Update BIOS

[F10] Enter Boot Menu

[F12] Network Boot

[F3] Disable Fast Boot is only displayed if at least one Fast Boot optimization is enabled.

If an unrecognized key is hit, then the BIOS will beep and wait for another keystroke. If one of the

listed hotkeys is hit, the BIOS will follow the indicated boot path. Password requirements must

still be honored.

If Disable Fast Boot is selected, the BIOS will disable all Fast Boot optimizations and reset the

system.

3.8

Hard Disk Drive Password Security Feature

The Hard Disk Drive Password Security feature blocks read and write accesses to the hard disk

drive until the correct password is given. Hard Disk Drive Passwords are set in BIOS SETUP and

are prompted for during BIOS POST. For convenient support of S3 resume, the system BIOS will

automatically unlock drives on resume from S3. Valid password characters are A-Z, a-z, and 0-9.

Passwords may be up to 19 characters in length.

The User hard disk drive password, when installed, will be required upon each power-cycle until

the Master Key or User hard disk drive password is submitted.

The Master Key hard disk drive password, when installed, will not lock the drive. The Master Key

hard disk drive password exists as an unlock override in the event that the User hard disk drive

password is forgotten. Only the installation of the User hard disk drive password will cause a hard

disk to be locked upon a system power-cycle.

Table 32 shows the effects of setting the Hard Disk Drive Passwords.

following prompt to force the user to enter the Master Key or User hard disk drive password:

Enter Hard Disk Drive Password:

Upon successful entry of the Master Key or User hard disk drive password, the system will

continue with normal POST.

If the hard disk drive password is not correctly entered, the system will go back to the above

prompt. The user will have three attempts to correctly enter the hard disk drive password. After

the third unsuccessful hard disk drive password attempt, the system will halt with the message:

Hard Disk Drive Password Entry Error

A manual power cycle will be required to resume system operation.

NOTE

The passwords are stored on the hard disk drive so if the drive is relocated to another computer

that does not support Hard Disk Drive Password Security feature, the drive will not be accessible.

Overview of BIOS Features

3.9

BIOS Security Features

The BIOS includes security features that restrict access to the BIOS Setup program and who can

boot the computer. A supervisor password and a user password can be set for the BIOS Setup

program and for booting the computer, with the following restrictions:



The supervisor password gives unrestricted access to view and change all the Setup options

in the BIOS Setup program. This is the supervisor mode.

The user password gives restricted access to view and change Setup options in the BIOS

Setup program. This is the user mode.

If only the supervisor password is set, pressing the <Enter> key at the password prompt of

the BIOS Setup program allows the user restricted access to Setup.

If both the supervisor and user passwords are set, users can enter either the supervisor

password or the user password to access Setup. Users have access to Setup respective to

which password is entered.



Setting the user password restricts who can boot the computer. The password prompt will be

displayed before the computer is booted. If only the supervisor password is set, the

computer boots without asking for a password. If both passwords are set, the user can enter

either password to boot the computer.



For enhanced security, use different passwords for the supervisor and user passwords.

Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to 20 characters in

length.



To clear a set password, enter a blank password after entering the existing password.
