CAT25320: 32-Kb SPI Serial CMOS EEPROM Memory

The CAT25320 is a 32-kb Serial CMOS EEPROM device internally organized as 4096x8 bits. This features a 32-byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS). In addition, the required bus signals are clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial communication with the CAT25320 device. The device features software and hardware write protection, including partial as well as full array protection.

Features
  • 10 MHz SPI compatible
  • 1.8 V to 5.5 V supply voltage range
  • SPI modes (0,0) & (1,1)
  • 32-Byte page write buffer
  • Self-timed write cycle
  • Hardware and software protection
  • 1,000,000 program/erase cycles
  • 100 year data retention
  • Industrial and Extended temperature range
  • Block write protection - Protect 1/4, 1/2 or all of EEPROM array
  • Low power CMOS technology
  • RoHS-compliant PDIP, SOIC, TSSOP 8-lead, TDFN and UDFN 8-pad packages
