1 / 22 page  2004 Microchip Technology Inc. DS21231D-page 1 25AA160/25LC160/25C160 Device Selection Table Features: • Low-power CMOS technology: - Write current: 3 mA maximum - Read current: 500 µA typical - Standby current: 500 nA typical • 2048 x 8-bit organization • 16 byte page • Write cycle time: 5 ms max. • Self-timed erase and write cycles • Block write protection: - Protect none, 1/4, 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: Description: The Microchip Technology Inc. 25AA160/25LC160/ 25C160 (25XX160*) are 16 Kbit Serial Electrically Erasable PROMs. The memory is accessed via a simple Serial Peripheral Interface™ (SPI™) compati- ble 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, transi- tions on its inputs will be ignored, with the exception of chip select, allowing the host to service higher priority interrupts.
