Description:

The Microchip Technology Inc. 25AA1024 is a 1024

Kbit serial EEPROM memory with byte-level and page-

level serial EEPROM functions. It also features Page,

Sector and Chip erase functions typically associated

with Flash-based products. These functions are not

required for byte or page write operations. 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

by a Chip Select (CS) input.

Communication to the device can be paused via the

hold pin (HOLD). While the device is paused, transi-

tions on its inputs will be ignored, with the exception of

Chip Select, allowing the host to service higher priority

interrupts.

The 25AA1024 is available in standard packages

including 8-lead PDIP and SOIJ, and advanced 8-lead

DFN package. All devices are Pb-free.
