DESCRIPTION  
The CAT25C128/256 is a 128K/256K-Bit SPI Serial  
CMOS EEPROM internally organized as 16Kx8/32Kx8  
bits. Catalyst’s advanced CMOS Technology  
substantially reduces device power requirements. The  
CAT25C128/256 features a 64-byte page write buffer.  
The device operates via the SPI bus serial interface  
and is enabled through 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 CAT25C128/256 is designed with software and  
hardware write protection features including Block Lock  
protection. The device is available in 8-pin DIP, 8-pin  
SOIC, 14-pin TSSOP and 20-pin TSSOP packages.
