Features:

Description:

• Max. Clock 20 MHz

The Microchip Technology Inc. 23X640 are 64 Kbit

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.

• Low-Power CMOS Technology:

- Read Current: 3 mA at 1 MHz

- Standby Current: 4 A Max. at +85°C

• 8192 x 8-bit Organization

• 32-Byte Page

• HOLD pin

Communication to the device can be paused via the

hold pin (HOLD). While the device is paused,

transitions on its inputs will be ignored, with the

exception of Chip Select, allowing the host to service

higher priority interrupts.

• Flexible Operating modes:

- Byte read and write

- Page mode (32 Byte Page)

- Sequential mode

The 23X640 is available in standard packages

including 8-lead PDIP and SOIC, and advanced

packaging including 8-lead TSSOP.

• Sequential Read/Write

• High Reliability

• Temperature Ranges Supported:

- Industrial (I):

-40C to +85C

-40C to +125C

Package Types (not to scale)

- Automotive (E):

• Pb-Free and RoHS Compliant, Halogen Free
