CAT25128

CAT25128 EEPROM Serial 128-Kb SPI Description The CAT25128 is a 128−Kb Serial CMOS EEPROM device internally organized as 16Kx8 bits. This features a 64−byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In addition, the required bus signals are clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial communication with the CAT25128 device. The device features software and hardware write protection, including partial as well as full array protection. On−Chip ECC (Error Correction Code) makes the device suitable for high reliability applications.* Features 20 MHz SPI Compatible 1.8 V to 5.5 V Supply Voltage Range SPI Modes (0,0) & (1,1) 64−byte Page Write Buffer Additional Identification Page with Permanent Write Protection 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 This Device is Pb−Free, Halogen Free/BFR Free, and RoHS Compliant VCC SI CS WP HOLD SCK CAT25128 SO VSS Figure 1.
