Features:

Description:

• Max. Clock 10 MHz

The Microchip Technology Inc. 25XX040A* is a 4 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.

• Low-Power CMOS Technology:

- Max. Write Current: 5 mA at 5.5V, 10 MHz

- Read Current: 5 mA at 5.5V, 10 MHz

- Standby Current: 5 μA at 5.5V

• 512 x 8-Bit Organization

• Write Page mode (up to 16 bytes)

• Sequential Read

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.

• Self-timed Erase and Write Cycles (5 ms max.)

• Block Write Protection:

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

• Built-in Write Protection:

The 25XX040A is available in standard packages

including 8-lead PDIP and SOIC, and advanced

packages including 8-lead MSOP, 8-lead TSSOP

and rotated TSSOP, 8-lead 2x3 DFN, and 6-lead

SOT-23.

- Power-on/off data protection circuitry

- Write enable latch

- Write-protect pin

• High Reliability:

- Endurance: 1,000,000 Erase/Write cycles

- Data retention: > 200 years

- ESD protection: > 4000V
