CAT25C33 - 32K/64K-Bit SPI Serial CMOS EEPROM

Download the CAT25C33 datasheet PDF. This datasheet also covers the CAT25C65 variant, as both devices belong to the same 32k/64k-bit spi serial cmos eeprom family and are provided as variant models within a single manufacturer datasheet.

Description

The CAT25C33/65 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.

Features

  • s 10 MHz SPI compatible s 1.8 to 6.0 volt operation s Hardware and software protection s Low power CMOS technology s SPI modes (0,0 &1,1) s Commercial, industrial, automotive and extended s 1,000,000 program/erase cycles s 100 year data tetention s Self-timed write cycle s 8-pin DIP/SOIC and 14-pin TSSOP s 64-byte page write buffer s Block write protection temperature ranges.
  • Protect first page, last page, any 1/4 or lower 1/2 of EEPROM array.
