Description:

• Max. Clock 10 MHz

The Microchip Technology Inc. 25AA640A/25LC640A

(25XX640A^*) are 64 kbit Serial Electrically Erasable

PROMs. The memory is accessed via a simple Serial

Peripheral Interface (SPI) compatible serial bus. The

bus signals required are a clock input (SCK) plus sep-

arate 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: 1 μA at 5.5V

• 8192 x 8-bit Organization

• 32 Byte Page

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 25XX640A is available in standard packages

including 8-lead PDIP and SOIC, and advanced

packaging including 8-lead MSOP, 8-lead TSSOP, DFN

and TDFN.

- Power-on/off data protection circuitry

- Write enable latch

- Write-protect pin

• Sequential Read

• High Reliability

Package Types (not to scale)

- Endurance: 1,000,000 erase/write cycles

- Data retention: > 200 years

- ESD protection: > 4000V

• Temperature Ranges Supported:
