DESCRIPTION

Temp Ranges I I,E The Microchip Technology Inc. 25C160 (25XX160*) are 16 Kbit Serial Electrically Erasable PROMs. The memory is accessed via a simple Serial Peripheral InterfaceTM (SPITM) 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.

FEATURES

Low power CMOS technology - Write current: 3 mA maximum - Read current: 500 A typical - Standby current: 500 nA typical x 8-bit organization 16 byte page Write cycle time: 5 ms max. Self-timed ERASE and WRITE cycles Block write protection - Protect none, 1/2 or all of array Built-in write protection - Power on/off data protection circuitry - Write enable latch - Write protect pin Sequential read High reliability - Endurance: 1 M cycles - Data retention: > 200 years - ESD protection: 4000V 8-pin PDIP and SOIC packages Temperature ranges supported: - Industrial (I): - Automotive (E) to +125C

*25XX160 is used in this document as a generic part number for the 25AA160/25LC160/25C160 devices. SPITM is a trademark of Motorola Inc.
