DESCRIPTION  
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.  
The CAT25C32/64 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 CAT25C32/  
64 features a 64-byte page write buffer. The device  
operates via the SPI bus serial interface and is enabled  
thoughaChipSelect(CS). InadditiontotheChipSelect,
