Description

The Microchip Technology Inc. 23A512/23LC512 are

512-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. Additionally, SDI

(Serial Dual Interface) and SQI (Serial Quad Interface)

is supported if your application needs faster data rates.

This device also supports unlimited reads and writes to

the memory array.
