1 / 18 page © Semiconductor Components Industries, LLC, 2012 January, 2012 − Rev. 23 1 Publication Order Number: CAT25010/D CAT25010, CAT25020, CAT25040 1-Kb, 2-Kb and 4-Kb SPI Serial CMOS EEPROM Description The CAT25010/20/40 are 1−Kb/2−Kb/4−Kb Serial CMOS EEPROM devices internally organized as 128x8/256x8/512x8 bits. They feature a 16−byte page write buffer and support the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In addition, the required bus signals are a clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial communication with the CAT25010/20/40 device. These devices feature software and hardware write protection, including partial as well as full array protection. Features • 20 MHz (5 V) SPI Compatible • 1.8 V to 5.5 V Supply Voltage Range • SPI Modes (0,0) & (1,1) • 16−byte Page Write Buffer • Self−timed Write Cycle • Hardware and Software Protection • Block Write Protection − Protect 1/4, 1/2 or Entire EEPROM Array • Low Power CMOS Technology • 1,000,000 Program/Erase Cycles • 100 Year Data Retention • Industrial and Extended Temperature Range • PDIP, SOIC, TSSOP 8−Lead and TDFN, UDFN 8−Pad Packages • These Devices are Pb−Free, Halogen Free/BFR Free, and RoHS Compliant SI SO CAT25010 CAT25020 CAT25040 SCK VSS VCC CS WP HOLD Figure 1.
