We'll need an integrated development environment and a compiler to program the Nuvoton N76E003AT20 microcontroller. These 8051 base microcontrollers can be programmed using a variety of software and compilers available on the market. However, Keil Vision is the most extensively used IDE for programming 8051-based microcontrollers because it includes a C51 compiler.
N76E00AT20 can be programmed through:
IDE: Keil u-vision
Compiler: C51
