The 25LC160 is a 16K bit Serial Electrically Erasable PROM with memory 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. The 25LC160 is capable of operation across a wide voltage range (2.5V to 5.5V) and a broad temperature range (-40°C to + 85°C). The 25LC160 is available in 8-pin PDIP, and SOIC (150 mil) packages.
