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 and SOIC, and advanced

packaging including 8-lead DFN and 8-lead TSSOP.

Pb-free (Pure Sn) finish is also available.
