DESCRIPTION  
required to access the device. The HOLD pin may be  
used to suspend any serial communication without  
resetting the serial sequence. The CAT25C64/128 is  
designed with software and hardware write protection  
features including Block write protection. The device is  
available in 8-pin DIP, 8-pin SOIC, 16-pin SOIC and 20-  
pin TSSOP packages.  
TheCAT25C64/128isa64K/128K-BitSPISerialCMOS  
E2PROM internally organized as 8Kx8/16Kx8 bits.  
Catalyst’s advanced CMOS Technology substantially  
reduces device power requirements. The CAT25C64/  
128 features a 64-byte page write buffer. The device  
operates via the SPI bus serial interface and is enabled  
thoughaChipSelect(CS). InadditiontotheChipSelect,
