25AA02E48/25AA02E64 (25AA02EXX) is a 2 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM).
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.
Note: 25AA02EXX is used in this document as a generic part number for the 25AA02E48/25AA02E64 devices.
Communication to the device can be paused via the hold pin (HOLD).
While the device is paused, transitions on its inputs will be ignored, with the exception of Chip Select, allowing the host to service higher priority interrupts.
The 25AA02EXX is a...
