CAT25320

32-Kb SPI Serial CMOS EEPROM

FEATURES

DESCRIPTION

10 MHz SPI compatible

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

1.8V to 5.5V supply voltage range

SPI modes (0,0) & (1,1)

¯¯

32-byte page write buffer

is enabled through a Chip Select (CS) input. In

addition, the required bus signals are clock input

(SCK), data input (SI) and data output (SO) lines. The

Self-timed write cycle

Hardware and software protection

Block write protection

¯¯¯¯¯

HOLD input may be used to pause any serial

communication with the CAT25320 device. The

device features software and hardware write protec–

tion, including partial as well as full array protection.

– Protect 1/4, 1/2 or entire EEPROM array

Low power CMOS technology

1,000,000 program/erase cycles

100 year data retention

Industrial temperature range

RoHS-compliant 8 lead PDIP, SOIC, TSSOP and

8-pad TDFN packages
