128K SPI Bus Serial EEPROM 8K-256K SPI Serial EEPROM High Temp Family Data Sheet 25LC128I-SN

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 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 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 alo available.
