Features:

Description:

• SPI-Compatible Bus Interface:

- 20 MHz Clock rate

The Microchip Technology Inc. 23A512/23LC512 are

512Kbit 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) plus separate data in (SI) and data

out (SO) lines. 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.

- SPI/SDI/SQI mode

• 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.

• 64K x 8-bit Organization:

- 32-byte page

The 23A512/23LC512 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

• Temperature Range Supported:

Package Types (not to scale)

- Industrial (I):

-40C to +85C

• Pb-Free and RoHS Compliant, Halogen Free

• 8-Lead SOIC, TSSOP and PDIP Packages
