Onsemi 64 Kb I2C CMOS Serial EEPROM, Part #N24S64B | EEPROM | DEX is a 64 Kb Serial CMOS EEPROM, internally organized as 8,192 words of 8 bits each. They feature a 32-byte page write buffer and support both the Standard (100 kHz), Fast (400 kHz) and Fast-Plus (1 MHz) I2C protocol. The devices also feature a 128-bit factory-set read-only Unique ID, a 32-byte Secure Data Page that can be permanently locked against future changes, and Software Write Protection of the entire array. A Device Configuration Register enables the user to specify the last 3 bits of the Device Address, allowing up to eight N24S64B devices to be addressed on the same bus.

Features: • Supports Standard, Fast and Fast-Plus I2C Protocol • 1.7 V to 5.5 V Supply Voltage Range • 32-byte Page Write Buffer • Lockable Secure Data Page • User Programmable Write Protection • User Programmable Device Address • 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 Temperature Range: −40°C to +85°C • Ultra-thin 4-ball WLCSP Package • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant
