25AA512/25LC512 SPI Serial EEPROM
Microchips 25AA512/25LC512 family of devices are 32 Kbit SPI Serial EEPROMs available in a variety of package, temperature and power supply variants. Featured are Page, Sector and Chip Erase functions typically associated with Flash based products.
The Serial Peripheral Interface (SPI) is utilised to provide the required Clock Input (SCK), Data In (SI) and Data Out (SO) signals. The operation of these devices can be paused via a Hold pin (HOLD) which causes inputs to be ignored with the exception higher priority interrupts defined via the Chip Select (CS) pin.
