23A256 - 256-Kbit SPI Bus Low-Power Serial SRAM
The Microchip Technology Inc.
23X256 is a 256-Kbit 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
