The Microchip Technology Inc. 25AA1024/25LC1024

(25XX1024^*) is a 1024 Kbit serial EEPROM memory

with byte-level and page-level serial EEPROM func-

tions. It also features Page, Sector and Chip erase

functions typically associated with Flash-based prod-

ucts. 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: 1μA 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 25XX1024 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:

- Endurance: 1M erase/write cycles
