Description

The Microchip Technology Inc. 23LCV1024 is a 1-Mbit

Serial SRAM device. 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, Serial Dual Interface

(SDI) is supported if the application needs faster data

rates.

This device also supports unlimited reads and writes to

the memory array and supports data backup via an

external battery/coin cell connected to VBAT (pin 7).
