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  
serialsequence.TheCAT25C11/03/05/09/17isdesigned  
with software and hardware write protection features  
including Block Write protection. The device is available  
in 8-pin DIP, 8-pin SOIC, 8/14-pin TSSOP and 8-pin  
MSOP packages.  
The CAT25C11/03/05/09/17 is a 1K/2K/4K/8K/16K-Bit  
SPI Serial CMOS EEPROM internally organized as  
128x8/256x8/512x8/1024x8/2048x8 bits. Catalyst’s  
advanced CMOS Technology substantially reduces  
device power requirements. The CAT25C11/03/05  
features a 16-byte page write buffer. The 25C09/17  
featuresa32-bytepagewritebuffer.Thedeviceoperates  
via the SPI bus serial interface and is enabled though a  
ChipSelect(CS).InadditiontotheChipSelect,theclock
