CAT24C128

EEPROM Serial 128-Kb I2C CAT24C128 Description The CAT24C128 is a EEPROM Serial 128−Kb I2C internally organized as 16,384 words of 8 bits each. It features a 64−byte page write buffer and supports both the Standard (100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I2C protocol. Write operations can be inhibited by taking the WP pin High (this protects the entire memory). On−Chip ECC (Error Correction Code) makes the device suitable for high reliability applications.* Features Supports Standard, Fast and Fast−Plus I2C Protocol 1.8 V to 5.5 V Supply Voltage Range 64−Byte Page Write Buffer Hardware Write Protection for Entire Memory Schmitt Triggers and Noise Suppression Filters on I2C Bus Inputs (SCL and SDA) Low Power CMOS Technology 1,000,000 Program/Erase Cycles 100 Year Data Retention Industrial and Extended Temperature Range This Device is Pb−Free, Halogen Free/BFR Free and RoHS Compliant** VCC SCL A2, A1, A0 WP CAT24C128 SDA VSS Figure 1.
