Features

Description

• SPI Bus Interface:

- SPI compatible

The Microchip Technology Inc. 23A1024/23LC1024

are 1 Mbit Serial SRAM devices. The memory is

accessed via a simple Serial Peripheral Interface (SPI)

compatible serial bus. The bus signals required are a

clock input (SCK), a data in line (SI) and a data out line

(SO). Access to the device is controlled through a Chip

Select (CS) input. Additionally, SDI (Serial Dual

Interface) and SQI (Serial Quad Interface) is supported

if your application needs faster data rates.

- SDI (dual) and SQI (quad) compatible

- 20 MHz Clock rate for all modes

• Low-Power CMOS Technology:

- Read Current: 3 mA at 5.5V, 20 MHz

- Standby Current: 4 A at +85°C

• Unlimited Read and Write Cycles

• Zero Write Time

This device also supports unlimited reads and writes to

the memory array.

• 128K x 8-bit Organization:

- 32-byte page

The 23A1024/23LC1024 is available in standard

packages including 8-lead SOIC, PDIP and advanced

8-lead TSSOP.

• Byte, Page and Sequential Mode for Reads and

Writes

• High Reliability

Package Types (not to scale)

• Temperature Ranges Supported:

- Industrial (I):

- Automotive (E):

-40C to +85C

-40C to +125C

• RoHS Compliant

SOIC/TSSOP/PDIP

• 8 Lead SOIC, TSSOP and PDIP Packages
