Description:

The Microchip Technology Inc. 25AA256/25LC256 (25XX256) are 256 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,

transitions on its inputs will be ignored, with the exception of Chip Select, allowing the host to service

higher priority interrupts.

The 25XX256 is available in standard packages including 8-lead PDIP and SOIC, and advanced

packaging including 8-lead DFN and 8-lead TSSOP
