DESCRIPTION
The CAT25C08/16 is a 8K/16K Bit SPI Serial CMOS
EEPROM internally organized as 1024x8/2048x8 bits.
Catalyst’s advanced CMOS Technology substantially
reduces device power requirements. The CAT25C08/
16 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 CAT25C08/16 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.
