2.1
FUNCTIONAL DESCRIPTION
Principles of Operation
The device is selected by pulling CS low. The 8-bit
READ instruction is transmitted to the
23A1024/23LC1024 followed by the 24-bit address,
with the first seven MSB’s of the address being “don’t
care” bits. After the correct READ instruction and
address are sent, the data stored in the memory at the
selected address is shifted out on the SO pin.
The 23A1024/23LC1024 is an 1 Mbit Serial SRAM
designed to interface directly with the Serial Peripheral
Interface (SPI) port of many of today’s popular
microcontroller families, including Microchip’s PIC®
microcontrollers. It may also interface with
microcontrollers that do not have a built-in SPI port by
using discrete I/O lines programmed properly in
firmware to match the SPI protocol. In addition, the
23A1024/23LC1024 is capable of operation in SDI and
SQI modes. In SDI mode, the SI and SO data lines are
bidirectional, allowing the transfer of two bits per clock
pulse. In SQI mode, two additional data lines enable
the transfer of four bits per clock pulse.
If operating in Sequential mode, the data stored in the
memory at the next address can be read sequentially
by continuing to provide clock pulses. The internal
Address Pointer is automatically incremented to the
next higher address after each byte of data is shifted
out. When the highest address is reached (1FFFFh),
the address counter rolls over to address 00000h,
allowing the read cycle to be continued indefinitely.
The read operation is terminated by raising the CS
pin.
The 23A1024/23LC1024 contains an 8-bit instruction
register. The device is accessed via the SI pin, with
data being clocked in on the rising edge of SCK. The
CS pin must be low for the entire operation.
2.4
Write Sequence
Table 2-1 contains a list of the possible instruction
bytes and format for device operation. All instructions,
addresses and data are transferred MSB first, LSB last.
Prior to any attempt to write data to the
23A1024/23LC1024, the device must be selected by
bringing CS low.
Once the device is selected, the Write command can
be started by issuing a WRITE instruction, followed by
the 24-bit address, with the first seven MSB’s of the
address being “don’t care” bits, and then the data to be
written. A write is terminated by the CS being brought
high.
2.2
Modes of Operation
The 23X1024 has three modes of operation that are
selected by setting bits 7 and 6 in the MODE register.
The modes of operation are Byte, Page and Burst.
Byte Operation – is selected when bits 7 and 6 in the
MODE register are set to 00. In this mode, the
read/write operations are limited to only one byte. The
Command followed by the 24-bit address is clocked into
the device and the data to/from the device is transferred
on the next eight clocks (Figure 2-1, Figure 2-2).
If operating in Page mode, after the initial data byte is
shifted in, additional bytes can be shifted into the
device. The Address Pointer is automatically
incremented. This operation can continue for the entire
page (32 bytes) before data will start to be overwritten.
If operating in Sequential mode, after the initial data
byte is shifted in, additional bytes can be clocked into
the device. The internal Address Pointer is
automatically incremented. When the Address Pointer
reaches the highest address (1FFFFh), the address
counter rolls over to (00000h). This allows the
operation to continue indefinitely, however, previous
data will be overwritten.
Page Operation – is selected when bits 7 and 6 in the
MODE register are set to 10. The 23X1024 has
4096 pages of 32 bytes. In this mode, the read and write
operations are limited to within the addressed page (the
address is automatically incremented internally). If the
data being read or written reaches the page boundary,
then the internal address counter will increment to the
start of the page (Figure 2-3, Figure 2-4).
Sequential Operation – is selected when bits 7 and 6
in the MODE register are set to 01. Sequential
operation allows the entire array to be written to and
read from. The internal address counter is automatically
incremented and page boundaries are ignored. When
the internal address counter reaches the end of the
array, the address counter will roll over to 0x00000
(Figure 2-5, Figure 2-6).

3.1
Chip Select (CS)
3.4
Serial Input, Serial I/O 0 (SI/SIO0)
A low level on this pin selects the device. A high level
deselects the device and forces it into Standby mode.
When the device is deselected, SO goes to the
high-impedance state, allowing multiple parts to share
the same SPI bus. After power-up, a low level on CS is
required, prior to any sequence being initiated.
The SI pin is used to transfer data into the device when
the SPI bus is being used. When in SDI or SQI bus
modes, the SI/SIO0 pin is a bidirectional I/O pin.
3.5
Serial Clock (SCK)
The SCK is used to synchronize the communication
between master and the 23A1024/23LC1024.
3.2
Serial Output, Serial I/O (SO/SIO1)
a
Instructions, addresses or data present on the SI pin
are latched on the rising edge of the clock input, while
data on the SO pin is updated after the falling edge of
the clock input.
The SO/SIO1 pin is used to transfer data out of the
23A1024/23LC1024 when the SPI bus is being used.
When in SDI or SQI bus modes, the SO/SIO1 pin is a
bidirectional I/O pin. Data is shifted out on this pin after
the falling edge of the serial clock, and it is latched in
on the rising edge of the serial clock.
3.6
Hold, Serial I/O 3 (HOLD/SIO3)
When the device is in SQI bus mode, pin HOLD/SIO3
is a bidirectional I/O pin. When in SPI or SDI bus
modes, the pin has the HOLD function.
3.3
Serial I/O 2 (SIO2)
The SIO2 pin is a bidirectional I/O pin used only in SQI
mode. If not using SQI bus mode, this pin should not be
left floating. Deciding to pull the SIO2 pin high would
allow successful recovery of the bus from SQI bus
mode in case an accidental EQIO command has been
registered.
The HOLD pin is used to suspend transmission to the
23A1024/23LC1024 while in the middle of a serial
sequence without having to avoid retransmitting the
entire sequence over again. It must be held high any
time this function is not being used. Once the device is
DS20005142C-page 12
2012-2015 Microchip Technology Inc.
23A1024/23LC1024
selected and a serial sequence is underway, the HOLD
pin may be pulled low to pause further serial
communication without resetting the serial sequence.
The HOLD pin should be brought low while SCK is low,
otherwise the HOLD function will not be invoked until
the
next
SCK
high-to-low
transition.
The
23A1024/23LC1024 must remain selected during this
sequence. The SI and SCK levels are “don’t cares”
during the time the device is paused and any
transitions on these pins will be ignored. To resume
serial communication, HOLD should be brought high
while the SCK pin is low, otherwise serial
communication will not be resumed until the next SCK
high-to-low transition.
The SO line will tri-state immediately upon a high-to low
transition of the HOLD pin, and will begin outputting
again immediately upon a subsequent low-to-high
transition of the HOLD pin, independent of the state of
SCK.
Hold functionality is not available when operating in
SQI bus mode.

DUAL AND QUAD SERIAL
MODE
The 23A1024/23LC1024 also supports SDI (Serial
Dual) and SQI (Serial Quad) mode of operation when
used with compatible master devices. As a convention
for SDI mode of operation, two bits are entered per
clock using the SIO0 and SIO1 pins. Bits are clocked
MSB first.
For SQI mode of operation, four bits of data are entered
per clock, or one nibble per clock. The nibbles are
clocked MSB first.
4.1
Dual Interface Mode
The 23A1024/23LC1024 supports Serial Dual Input
(SDI) mode of operation. To enter SDI mode the EDIO
command must be clocked in (Figure 4-1). It should be
noted that if the MCU resets before the SRAM, the user
will need to determine the serial mode of operation of
the SRAM and reset it accordingly. Byte read and write
sequence in SDI mode is shown in Figure 4-2 and
Figure 4-3.

In addition to the Serial Dual interface (SDI) mode of
operation Serial Quad Interface (SQI) is also
supported. In this mode the HOLD functionality is not
available. To enter SQI mode the EQIO command must

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

applications and the like is provided only for your convenience
