Description and Introduction

2K-Bit Standard 2-Wire Bus The **NM24C03M8** is a serial Electrically Erasable Programmable Read-Only Memory (EEPROM) integrated circuit designed for non-volatile data storage in a variety of electronic applications. With a storage capacity of **3 Kbits (384 x 8 bits)**, this device is well-suited for storing configuration settings, calibration data, and other critical system parameters that must be retained when power is removed.  

Operating on a **single 2.5V to 5.5V supply**, the NM24C03M8 supports **I²C (Inter-Integrated Circuit) communication**, ensuring compatibility with a wide range of microcontrollers and digital systems. Its **low-power consumption** makes it ideal for battery-powered devices, while its **endurance rating of 1 million write cycles** ensures reliable performance over extended use.  

The NM24C03M8 features a **16-byte page write buffer**, enabling efficient data updates, and includes built-in **write protection** to prevent accidental data corruption. Available in an **8-pin SOIC package**, it offers a compact footprint suitable for space-constrained designs.  

Common applications include **consumer electronics, industrial control systems, automotive modules, and IoT devices**, where reliable, low-power non-volatile memory is essential. Its robust design and industry-standard interface make it a versatile choice for engineers seeking dependable EEPROM functionality.

Application Scenarios & Design Considerations

2K-Bit Standard 2-Wire Bus

Alternative Part Number

  • AT24C03-10PC --: Pin-compatible 2-wire serial EEPROM with the same 2K-bit density and DIP-8 package, widely available and a common drop-in replacement.
  • 24LC02B-I/P --: I2C serial EEPROM in DIP-8 with comparable 2K-bit organization and voltage range, suitable for most NM24C03 applications.
  • CAT24C02LI --: Low-power I2C EEPROM in DIP-8 with similar 2K-bit capacity and interface, offering a cost-effective alternative from a major supplier.
  • AT24C02-10PU-2.7 --: Pin-compatible 2K-bit I2C serial EEPROM in 8-pin DIP, widely available and functionally equivalent to the NM24C03 for most designs.
  • CAT24C02LI-G --: 2K-bit I2C serial EEPROM in 8-pin package with compatible protocol and timing, suitable as an alternative source.
