H EE GEN FR ALO CAT25C32/64 32K/64K-Bit SPI Serial CMOS EEPROM LE FEATURES A D F R E ETM ■ 1,000,000 program/erase cycles ■ 10 MHz SPI compatible ■ 100 year data tetention ■ 1.8 to 6.0 volt operation ■ Self-timed write cycle ■ Hardware and software protection ■ 8-pin DIP/SOIC, 14-pin TSSOP and 20-pin ■ Low power CMOS technology TSSOP ■ SPI modes (0,0 &1,1) ■ 64-Byte page write buffer ■ Commercial, industrial and automotive ■ Block write protection temperature ranges – Protect 1/4, 1/2 or all of EEPROM array DESCRIPTION The CAT25C32/64 is a 32K/64K-Bit SPI Serial CMOS EEPROM internally organized as 4Kx8/8Kx8 bits. Catalyst’s advanced CMOS Technology substantially reduces device power requirements. The CAT25C32/ 64 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 HOLD pin may be used to suspend any serial communication without resetting the serial sequence. The CAT25C32/64 is designed with software and hardware write protection features including Block write protection. The device is available in 8-pin DIP, 8-pin SOIC, 14-pin TSSOP and 20-pin TSSOP packages.
