23LCV1024-I/ST, SRAM 1024K 2.5V SPI SERIAL SRAM Vbat

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 V BAT. 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.
