DESCRIPTION
The CAT25C01/02/04/08/16 is a 1K/2K/4K/8K/16K Bit
SPI Serial CMOS E
2
PROM internally organized as
128x8/256x8/512x8/1024x8/2048x8 bits. Catalyst’s ad-
vanced CMOS Technology substantially reduces de-
vice power requirements. The CAT25C01/02/04 fea-
tures a 16-byte page write buffer. The 25C08/16 fea-
tures 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 CAT25C01/02/04/08/16 is de-
signed with software and hardware write protection
features including Block Write protection. The device is
available in 8-pin DIP, 8-pin SOIC, 8-pin MSOP and 8/
14-pin TSSOP packages.
