DESCRIPTION  
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 CAT25C01/02/04/08/16 is de-  
signed with software and hardware write protection  
features including Block Write protection. The device is  
available in 8-pin DIP, 8-pin SOIC, 8-pin MSOP and 8/  
14-pin TSSOP packages.  
The CAT25C01/02/04/08/16 is a 1K/2K/4K/8K/16K Bit  
SPI Serial CMOS E2PROM internally organized as  
128x8/256x8/512x8/1024x8/2048x8 bits.Catalyst’sad-  
vanced CMOS Technology substantially reduces de-  
vice power requirements. The CAT25C01/02/04 fea-  
tures a 16-byte page write buffer. The 25C08/16 fea-  
tures a 32-byte page write buffer.The device operates  
via the SPI bus serial interface and is enabled though a  
ChipSelect(CS).InadditiontotheChipSelect,theclock
