DESCRIPTION  
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 CAT25010/  
20/40 is designed with software and hardware write  
protectionfeaturesincludingBlockWriteprotection.The  
deviceisavailablein8-pinDIP, 8-pinSOIC, 8-pinMSOP  
and 8-pin TSSOP packages.  
The CAT25010/20/40 is a 1K/2K/4K Bit SPI Serial  
CMOS EEPROM internally organized as 128x8/256x8/  
512x8 bits. Catalyst’s advanced CMOS Technology  
substantially reduces device power requirements. The  
CAT25010/20/40 features a 16-byte page write buffer.  
The device operates via the SPI bus serial interface and  
is enabled though a Chip Select (CS). In addition to the
