1K/2K/4K SPI Serial CMOS EEPROM
DESCRIPTION
The CAT25C01/02/04 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. The
CAT25C01/02/04 features a 16-byte page write buffer.
The device operates via the SPI bus serial interface 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
HOLD
pin may be used to suspend any serial communication
without resetting the serial sequence. The CAT25C01/
02/04 is designed with software and hardware write
protection features including Block Write protection. The
device is available in 8-pin DIP, 8-pin SOIC and 8-pin
TSSOP packages.
