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?) compati-
ble 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
Features:
? Low-power CMOS technology:
- Write current: 3 mA maximum
- Read current: 500 μ A typical
- Standby current: 500 nA typical
? 1024 x 8-bit organization
? 16 byte page
? Write cycle time: 5 ms max.
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.
Package Types
PDIP/SOIC
? 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
