24AA128-I/SN MICROCHIP EEPROM

The 24AA128-I/SN is a 128Kbit I²C-compatible serial EEPROM from Microchip Technology, organized as 16K x 8 bits in an 8-pin SOIC package. For selection, verify the supply voltage range of 1.7V to 5.5V, ensure the I²C bus supports up to 400kHz clock frequency (note that at VCC < 2.5V, the maximum frequency is 100kHz), confirm the industrial temperature range of -40°C to +85°C, and note the 5ms page write cycle time. Key features include a 64-byte page write buffer, hardware write-protect pin, cascadable up to eight devices (supporting up to 1Mbit address space via address pins A0/A1/A2), typical standby current of 100nA, and >200 years of data retention. Ideal applications include personal communication devices, data acquisition systems, portable medical instruments, industrial control modules, smart meters, consumer electronics, and battery-powered devices requiring reliable non‑volatile memory.
