CAT25C64S-TE13

64Kbit SPI Serial CMOS EEPROM

DESCRIPTION

The CAT25C64 is a 64K-Bit SPI Serial CMOS EEPROM internally organized as 8Kx8 bits. ’s advanced CMOS Technology substantially reduces device power requirements. The CAT25C64 features a 64-byte page write buffer. The device operates via the SPI bus serial interface 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 HOLDpin may be used to suspend any serial communication without resetting the serial se quence. The CAT25C64 is designed with software and hardware write protection features including Block write protection. The device is available in 8-pin DIP and SOIC packages.
