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 E

PROM

internally organized as 256x8/512x8/1024x8/2048x8/

4096x8 bits. Catalyst’s advanced CMOS Technology

substantially reduces device power requirements. The

2K/4K devices feature a 16-byte page write buffer. The

8K/16K/32K devices feature a 32-byte page write

buffer.The device operates via the SPI bus serial inter-

face 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 reset function of the 25CXXX protects the

system during brown out and power up/down condtions.

During system failure the watchdog timer feature pro-

tects the microcontroller with a reset signal. The

CAT25CXXX is designed with software and hardware

write protection features including Block Lock protec-

tion. The device is available in 8-pin DIP, 8-pin SOIC, 16-

pin SOIC and 14-pin TSSOP packages.
