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
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 available in the standard 8-lead
SOIC and 6-lead SOT-23 packages.
