Part Desription

The AT90CAN32/64/128 is a low-power CMOS 8-bit microcontroller based on the AVR

enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the

AT90CAN32/64/128 achieves throughputs approaching 1 MIPS per MHz allowing the system

designer to optimize power consumption versus processing speed.

The AVR core combines a rich instruction set with 32 general purpose working registers. All 32

registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent

registers to be accessed in one single instruction executed in one clock cycle. The resulting

architecture is more code efficient while achieving throughputs up to ten times faster than con-

ventional CISC microcontrollers.

AT90CAN32/64/128

The AT90CAN32/64/128 provides the following features: 32K/64K/128K bytes of In-System Pro-

grammable Flash with Read-While-Write capabilities, 1K/2K/4K bytes EEPROM, 2K/4K/4K

bytes SRAM, 53 general purpose I/O lines, 32 general purpose working registers, a CAN con-

troller, Real Time Counter (RTC), four flexible Timer/Counters with compare modes and PWM, 2

USARTs, a byte oriented Two-wire Serial Interface, an 8-channel 10-bit ADC with optional differ-

ential input stage with programmable gain, a programmable Watchdog Timer with Internal

Oscillator, an SPI serial port, IEEE std. 1149.1 compliant JTAG test interface, also used for

accessing the On-chip Debug system and programming and five software selectable power sav-

ing modes.

The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI/CAN ports and

interrupt system to continue functioning. The Power-down mode saves the register contents but

freezes the Oscillator, disabling all other chip functions until the next interrupt or Hardware

Reset. In Power-save mode, the asynchronous timer continues to run, allowing the user to main-

tain a timer base while the rest of the device is sleeping. The ADC Noise Reduction mode stops

the CPU and all I/O modules except Asynchronous Timer and ADC, to minimize switching noise

during ADC conversions. In Standby mode, the Crystal/Resonator Oscillator is running while the

rest of the device is sleeping. This allows very fast start-up combined with low power

consumption.

The device is manufactured using Atmel’s high-density nonvolatile memory technology. The On-

chip ISP Flash allows the program memory to be reprogrammed in-system through an SPI serial

interface, by a conventional nonvolatile memory programmer, or by an On-chip Boot program

running on the AVR core. The boot program can use any interface to download the application

program in the application Flash memory. Software in the Boot Flash section will continue to run

while the Application Flash section is updated, providing true Read-While-Write operation. By

combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip,

the Atmel AT90CAN32/64/128 is a powerful microcontroller that provides a highly flexible and

cost effective solution to many embedded control applications.

The AT90CAN32/64/128 AVR is supported with a full suite of program and system development

tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit emula-

tors, and evaluation kits.

Note:

The large center pad underneath the QFN package is made of metal and internally connected to

GND. It should be soldered or glued to the board to ensure good mechanical stability. If the center

pad is left unconnected, the package might loosen from the board.

1.5.2

1.5.3

GND

Ground.

Port A (PA7..PA0)

Port A is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The

Port A output buffers have symmetrical drive characteristics with both high sink and source

capability. As inputs, Port A pins that are externally pulled low will source current if the pull-up

resistors are activated. The Port A pins are tri-stated when a reset condition becomes active,

even if the clock is not running.

Port A also serves the functions of various special features of the AT90CAN32/64/128 as listed

on I/O-Ports paragraph of the complete Datasheet.

Port B output buffers have symmetrical drive characteristics with both high sink and source

capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up

resistors are activated. The Port B pins are tri-stated when a reset condition becomes active,

even if the clock is not running.

can provide internal pull-up resistors (selected for each bit). The Port F output buffers have sym-

metrical drive characteristics with both high sink and source capability. As inputs, Port F pins

that are externally pulled low will source current if the pull-up resistors are activated. The Port F

pins are tri-stated when a reset condition becomes active, even if the clock is not running.

Port F also serves the functions of the JTAG interface. If the JTAG interface is enabled, the pull-

up resistors on pins PF7(TDI), PF5(TMS), and PF4(TCK) will be activated even if a reset occurs.

1.5.9

Port G (PG4..PG0)

Port G is a 5-bit I/O port with internal pull-up resistors (selected for each bit). The Port G output

buffers have symmetrical drive characteristics with both high sink and source capability. As

on I/O-Ports paragraph of the complete Datasheet.

1.5.10

RESET

Reset input. A low level on this pin for longer than the minimum pulse length will generate a

reset. The minimum pulse length is given in characteristics. Shorter pulses are not guaranteed

to generate a reset. The I/O ports of the AVR are immediately reset to their initial state even if

the clock is not running. The clock is needed to reset the rest of the AT90CAN32/64/128.

Output from the inverting Oscillator amplifier.

AVCC is the supply voltage pin for the A/D Converter on Port F. It should be externally con-

nected to V_CC, even if the ADC is not used. If the ADC is used, it should be connected to V_CC

through a low-pass filter.

1.5.14

AREF

This is the analog reference pin for the A/D Converter.

Notes: 1. Address bits exceeding PCMSB (c.f. complete Datasheet) are don’t care.

2. Address bits exceeding EEAMSB (c.f. complete Datasheet) are don’t care.

3. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses

should never be written.

4. I/O Registers within the address range 0x00 - 0x1F are directly bit-accessible using the SBI and CBI instructions. In these

registers, the value of single bits can be checked by using the SBIS and SBIC instructions.

5. Some of the status flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI

instructions will only operate on the specified bit, and can therefore be used on registers containing such status flags. The

CBI and SBI instructions work with registers 0x00 to 0x1F only.

6. When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When addressing I/O

Registers as data space using LD and ST instructions, 0x20 must be added to these addresses. The AT90CAN32/64/128 is

a complex microcontroller with more peripheral units than can be supported within the 64 location reserved in Opcode for

the IN and OUT instructions. For the Extended I/O space from 0x60 - 0xFF in SRAM, only the ST/STS/STD and

LD/LDS/LDD instructions can be used.
