CAT24M01

EEPROM Serial 1-Mb I2C CAT24M01 Description The CAT24M01 is a EEPROM Serial 1−Mb I2C, internally organized as 131,072 words of 8 bits each. It features a 256−byte page write buffer and supports 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). External address pins make it possible to address up to four CAT24M01 devices on the same bus. 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 256−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 8−pin, SOIC, TSSOP and 8−pad UDFN Packages These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant VCC SCL A2, A1 WP CAT24M01 SDA VSS Figure 1.
