DESCRIPTION
The CAT25C03/05/09/17/33 is a 2K/4K/8K/16K/32K-Bit
SPI Serial CMOS E2PROM internally organized as
256x8/512x8/1024x8/2048x8/4096x8
bits. Catalyst’s
advanced CMOS Technology substantially reduces de-
vice power requirements. The CAT25C03/05 features a
16-byte page write buffer. The 25C09/17/33 features a
32-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 CAT25C03/05/09/17/33 is de-
signed with software and hardware write protection
features. The device is available in 8-pin DIP, 8-pin
SOIC, 16-pin SOIC, 8-pin TSSOP and 14-pin TSSOP
packages.
