CAT25010, CAT25020, CAT25040  
1K/2K/4K SPI Serial CMOS EEPROM  
FEATURES  
DESCRIPTION  
I 10 MHz SPI compatible  
I 1.8 to 5.5 volt operation  
I SPI modes (00 & 11)  
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). 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  
protection features including Block Write protection.  
I 16-byte page write buffer  
I Self-timed write cycle  
I Hardware and software protection  
I Block write protection  
– Protect 1/4, 1/2 or all of EEPROM array  
I Low power CMOS technology  
I 1,000,000 program/erase cycles  
I 100 year data retention  
I Industrial temperature range  
I RoHS-compliant 8-lead PDIP, SOIC, TSSOP  
and 8-pad TDFN packages.
