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, SDI (Serial Dual Inter-
face) is supported if your 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).
The 23LCV1024 is available in standard packages
including 8-lead SOIC, PDIP and advanced 8-lead
TSSOP.
