Overview

The 25LC128-I/SN is a 128 Kbit Serial Electrically Erasable PROM (EEPROM) that interfaces via the Serial Peripheral Interface (SPI) bus. Organized as 16K x 8 bits, it supports a wide voltage range of 2.5V to 5.5V and operates at clock speeds up to 10 MHz.

Why Choose This Part

This EEPROM offers a low standby current of only 5 uA and a maximum operating current of 5 mA at 5.5V. The 10 MHz SPI interface provides faster data throughput compared to I2C-based alternatives while maintaining a small 8-pin SOIC footprint.

Applications

Firmware Configuration Storage
Ideal for storing calibration data, device settings, and user preferences in embedded systems.
Data Logging
Serves as non-volatile storage for sensor readings and event logs in industrial monitoring equipment.
Parameter Backup
Used in consumer electronics to retain state information during power cycles without requiring a battery.

Getting Started

To integrate this part, connect the SPI pins (CS, SCK, SI, SO) to a microcontroller and ensure a 0.1uF bypass capacitor is placed near the VDD pin. Microchip provides the MPLAB XC8 compiler and standard SPI libraries that support the common 25-series instruction set.

Also Consider

25LC256-I/SN MCHPMicrochip Technology - Provides double the memory capacity (256 Kbit) in the same 8-SOIC footprint and pinout.
