Description
The
Microchip
Technology
Inc.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 25AA02
