25AA320AX-I/MS Datasheet PDF - Microchip Technology

Description:
The Microchip Technology Inc. 25AA320A/25LC320A (25XX320A*) are 32 kbit Serial Electrically Erasable PROMs. 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.
