DESCRIPTION
The CAT25C64 is a 64K-Bit SPI Serial CMOS EEPROM
internally organized as 8Kx8 bits. Catalyst’s advanced
CMOS Technology substantially reduces device power
requirements. The CAT25C64 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 se-
quence. The CAT25C64 is designed with software and
hardware write protection features including Block write
protection. The device is available in 8-pin DIP and
SOIC packages.
