As one of the most popular 8051 microcontrollers, the N76E003 from Nuvoton Technology is now complemented by the N76S003, allowing for a seamless replacement.

Both models utilize the 1T 8051 core, operate at a frequency of 16 MHz, support a wide operating voltage range of 2.4V to 5.5V, and feature high anti-interference capabilities with 7 kV ESD and 4 kV EFT ratings. They are also suitable for industrial control environments with an operating temperature range of -40°C to 105°C.

With the same 20-pin package, the N76S003 offers up to 18 I/O pins and is designed to be fully pin-to-pin compatible with the N76E003. This allows users to not only directly replace the hardware but also achieve a "Code to Code" design, enabling a painless transition of existing code to the new IC. Additionally, users can continue to use all existing Nuvoton tools without needing to learn new ones.

The features of N76S003 series:

The main difference is that the new N76S003 provides more memory within the same package, enhancing processing efficiency. The Flash/SRAM capacity has been increased from 18KB/256+768 Bytes in the N76E003 to 18KB/256+1K Bytes in the N76S003.
