DESCRIPTION
The CAT25CXXX is a single chip solution to three popular functions of EEPROM Memory, precision reset controller and watchdog timer. The EEPROM Memory is a 2K/4K/8K/16K/32K-Bit SPI Serial CMOS E2PROM internally organized as 256x8/512x8/1024x8/2048x8/ 4096x8 bits. Catalystâs advanced CMOS Technology substantially reduces device power requirements. The 2K/4K devices feature a 16-byte page write buffer.
