Description:
The Microchip Technology Inc. 25AA128/25LC128
(25XX128 * ) are 128k-bit 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,
transitions on its inputs will be ignored, with the
exception of Chip Select, allowing the host to service
higher priority interrupts.
The 25XX128 is available in standard packages
including 8-lead PDIP, SOIJ and SOIC, and
advanced packaging including 8-lead DFN and 8-
lead TSSOP.
