CAT25040

The CAT25010/20/40 is a 1K/2K/4K Bit SPI Serial CMOS EEPROM internally organized as 128x8/256x8/ 512x8 bits. Catalyst's advanced CMOS Technology substantially reduces device power requirements. The CAT25010/20/40 features a 16-byte page write buffer.The device operates via the SPI bus serial terface and is enabled though a Chip Select (CS). In addition to the Chip Select, the clock input (SCK), data in (SI) and data out (SO) are required to access the device. The HOLD pin may be used to suspend any serial communication without resetting the serial sequence. The CAT25010/ 20/40 is designed with software and hardware write protection features including Block Write protection. The device is available in 8-pin DIP, 8-pin SOIC, 8-pin MSOP and 8-pin TSSOP packages.
