CAT25080

EEPROM Serial 8/16-Kb SPI CAT25080, CAT25160 Description The CAT25080/25160 are a EEPROM Serial 8/16−Kb SPI devices internally organized as 1024x8/2048x8 bits. They feature a 32−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 CAT25080/25160 device. These devices feature software and hardware write protection, including partial as well as full array protection. Features 20 MHz SPI (5 V) Compatible 1.8 V to 5.5 V Supply Voltage Range SPI Modes (0,0) & (1,1) 32−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 8−lead SOIC, TSSOP and 8−pad, UDFN Packages These Devices are Pb−Free, Halogen Free/BFR Free, and RoHS Compliant VCC SI CS CAT25080 WP CAT25160 SO HOLD SCK VSS Figure 1.
