NV24C256MUW

EEPROM Serial 256-Kb I2C - Automotive Grade 1 in Wettable Flank UDFN Package NV24C256MUW Description The NV24C256 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 NV24C256 devices on the same bus. On−Chip ECC (Error Correction Code) makes the device suitable for high reliability applications. Features Automotive AEC−Q100 Grade 1 (−40°C to +125°C) Qualified Supports Standard, Fast and Fast−Plus I2C Protocol 2.5 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 UDFN−8 Wettable Flank Package This Device is Pb−Free, Halogen Free/BFR Free, and RoHS Compliant VCC SCL A2, A1, A0 WP NV24C256 SDA VSS Figure 1.
