Pin Function Table

Description:

The Microchip Technology Inc. 25XX040A* is a 4 Kbit

Serial Electrically Erasable Programmable Read-Only

Memory (EEPROM). 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

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 25XX040A is available in standard packages

including 8-lead PDIP and SOIC, and advanced

packages including 8-lead MSOP, 8-lead TSSOP

and rotated TSSOP, 8-lead 2x3 DFN, and 6-lead

SOT-23.
