The 25AA640 is a 64K-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 25AA640 is capable of operation across a wide voltage range (1.8V to 5.5V) and commercial temperature range (0°C to + 70°C). The 25AA640 is available in 8-pin PDIP, SOIC and TSSOP packages.
