Pin Function Table

Description:

The Microchip Technology Inc. 23X256 are 256 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.

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.

The 23X256 is available in standard packages

including 8-lead PDIP and SOIC, and advanced

packaging including 8-lead TSSOP.
