DESCRIPTION
The CAT25C33/65 is a 32K/64K-Bit SPI Serial CMOS
EEPROM internally organized as 4Kx8/8Kx8 bits.
Catalyst’s advanced CMOS Technology substantially
reduces device power requirements. The CAT25C33/
65 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 CAT25C32/64 is
designed with software and hardware write protection
features including Block write protection. The device is
available in 8-pin DIP, 8-pin SOIC, 14-pin TSSOP and
20-pin TSSOP packages.
