Microchip Technology 23LCV512 / 23LCV1024 Serial SRAM

Microchip 23LCV512 and 23LCV1024 are 512Kb and 1Mb Serial SRAM devices accessed via a simple SPI compatible serial bus. These Microchip SRAM devices support unlimited reads and write to the memory array and support data backup via external battery/coin cell connected to VBAT. The bus signals required are a clock input plus separate data in and data outlines. Access to the device is controlled through a Chip Select input. Additionally, SDI (Serial Dual Interface) is supported if an application needs faster data rates.
