The Microchip Technology Inc. 25AA080C is an 8 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 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, transitions on its inputs will be ignored, with the exception of Chip Select, allowing the host to service higher priority interrupts. The 25AA080C is available in standard packages including 8-lead PDIP and SOIC, and advanced packaging including 8-lead MSOP, TSSOP, and 2x3 TDFN. All packages are Pb-free and RoHS compliant.
