23A512 512Kbit SPI Serial SRAM

The Microchip Technology Inc. 23A512/23LC512 are 512-Kbit Serial SRAM devices. 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 con.
