Description:
The Microchip Technology Inc. 25AA320A/25LC320A
(25XX320A * ) 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 sep-
arate 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.
The 25XX320A is available in standard packages
including 8-lead PDIP and SOIC, and advanced
packaging including 8-lead MSOP, TSSOP and 2x3
TDFN.
Package Types (not to scale)
- Data retention: > 200 years
- ESD protection: > 4000V
