Description:

• 20 MHz max. Clock Speed

• Byte and Page-level Write Operations:

- 256 byte page

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.

- 6 ms max. write cycle time

- No page or sector erase required

• Low-Power CMOS Technology:

- Max. Write current: 5 mA at 5.5V, 20 MHz

- Read current: 7 mA at 5.5V, 20 MHz

- Standby current: 1A at 2.5V

(Deep power-down)

• Electronic Signature for Device ID

• Self-Timed Erase and Write Cycles:

- Page Erase (6 ms max.)

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.

- Sector Erase (10 ms max.)

- Chip Erase (10 ms max.)

• Sector Write Protection (32K byte/sector):

- Protect none, 1/4, 1/2 or all of array

The 25AA1024 is available in standard packages

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

DFN package. All devices are Pb-free.

• Built-In Write Protection:

- Power-on/off data protection circuitry

- Write enable latch

- Write-protect pin

• High Reliability:

Package Types (not to scale)

- Endurance: 1M erase/write cycles

- Data Retention: >200 years

- ESD Protection: 4000V
