Microchip | 25AA160B-I/SN

Note: Not Recommended for new designs.

The 25AA160A/B (25XX160A/B*) series of 16 Kbit Serial Electrically Erasable PROMs 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 25XX160A/B is available in standard Pb-free packages including 8-lead PDIP and SOIC, and advanced packaging including 8-lead MSOP, and 8-lead TSSOP
