The Microchip Technology Inc. 25XX020A* is a 2 KbitSerial Electrically Erasable Programmable Read-OnlyMemory (EEPROM). The memory is accessed via asimple Serial Peripheral Interface (SPI) compaTIbleserial 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 ChipSelect (CS) input.CommunicaTIon to the device can be paused via thehold pin (HOLD). While the device is paused, transiTIonson its inputs will be ignored, with the excepTIon ofChip Select, allowing the host to service higher priorityinterrupts.The 25XX020A is available in standard packagesincluding 8-lead PDIP and SOIC, and advancedpackages including 8-lead MSOP, 8-lead TSSOP androtated TSSOP, 8-lead 2x3 DFN, and 6-lead SOT-23.
