CAT25040 - 1K/2K/4K SPI Serial CMOS EEPROM

Download the CAT25040 datasheet PDF. This datasheet also covers the CAT25010 variant, as both devices belong to the same 1k/2k/4k spi serial cmos eeprom family and are provided as variant models within a single manufacturer datasheet.

General Description

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.
