CAT24C256

EEPROM Serial 256-Kb I2C CAT24C256 Description The CAT24C256 is a EEPROM Serial 256−Kb I2C, internally organized as 32,768 words of 8 bits each. It features a 64−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 eight CAT24C256 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 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 SOIC, TSSOP and UDFN 8−Pad Packages This Device is Pb−Free, Halogen Free/BFR Free, and RoHS Compliant VCC SCL A2, A1, A0 WP CAT24C256 SDA DATA SHEET www.onsemi.com TSSOP−8 Y SUFFIX CASE 948AL SOIC−8 W SUFFIX CASE 751BD UDFN−8 HU4 SUFFIX CASE 517AZ PIN CONFIGURATION A0 1 A1 VCC WP A2 SCL VSS SDA SOIC (W, X), TSSOP (Y), UDFN (HU4) For the location of Pin 1, please consult the corresponding package drawing.
