Description:

The Microchip Technology Inc. 25AA080/25LC080/

25C080 (25XX080

) are 8 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 separate data in (SI) and data out (SO)

lines. Access to the device is controlled through 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.

Features:

• Low-power CMOS technology:

- Write current: 3 mA maximum

- Read current: 500

A

typical

- Standby current: 500 nA typical

• 1024 x 8-bit organization

• 16 byte page

• Write cycle time: 5 ms max.

• Self-timed erase and write cycles

• Block write protection:

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

• Built-in write protection:

- Power-on/off data protection circuitry

- Write enable latch

- Write-protect pin

• Sequential read

• High reliability:

- Endurance: 1 M cycles

- Data retention: > 200 years

- ESD protection: > 4000V

• 8-pin PDIP and SOIC (150 mil)

• Temperature ranges supported:

- Industrial (I):

-40C to +85C

- Automotive (E) (25C080):

-40°C to +125°C
