DESCRIPTION
The CAT25C128/256 is a 128K/256K-Bit SPI Serial
CMOS E2PROM internally organized as 16Kx8/32Kx8
bits. Catalyst’s advanced CMOS Technology substan-
tially reduces device power requirements. The
CAT25C128/256 features a 64-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 CAT25C128/
256 is designed with software and hardware write pro-
tection features including Block Lock protection. The
device is available in 8-pin DIP, 8-pin SOIC, 16-pin
SOIC, 14-pin TSSOP and 20-pin TSSOP packages.
