The Microchip Technology Inc. 25AA320/25LC320/
25C320 (25XX320 * ) are 32 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
Features:
? Low-Power CMOS Technology:
- Write current: 3 mA maximum
- Read current: 500 μ A, typical
- Standby current: 500 nA, typical
? 4096 x 8 Bit Organization
? 32 Byte Page
Select (CS) input.
Communication to the device can be paused via the
hold pin (HOLD). While the device is paused,
transitions on its inputs will be ignored, with the
exception of Chip Select, allowing the host to service
higher priority interrupts.
