N76E003 USB ICP Programmer

Description

Overview

The N76E003 USB ICP Programmer is a compact USB-based in-circuit programmer designed for the Nuvoton N76E003 microcontroller family. It connects directly to the target board through the ICPDA, ICPCK, VCC, and GND pins, providing a convenient way to program and manage the MCU without removing it from the target PCB.

The programmer is enumerated as a USB CDC virtual COM port, so it does not require a dedicated USB driver on the PC. It supports programming the user application into APROM, programming a bootloader into LDROM, and managing configuration and erase operations.

Key Features

• Designed for Nuvoton N76E003 microcontrollers
• USB In-Circuit Programming (ICP) interface
• USB CDC virtual COM port — no special USB driver required
• Programs user firmware into APROM
• Programs bootloader firmware into LDROM
• Supports reading and writing Configuration Bits
• Supports Full Erase and Partial Erase
• Connects to the target using only:
  • ICPDA
  • ICPCK
  • VCC
  • GND
• Compact design for convenient development and production use
• Useful for both development boards and custom N76E003-based PCBs

Programming Interface

Connect the programmer to the target N76E003 board as follows:

No additional programming components are required on the target board when the appropriate ICP connections are available.

Programming Functions

The programmer can be used for:

• APROM Programming — download the user’s application firmware.
• LDROM Programming — program a bootloader into the MCU’s LDROM area.
• Configuration Bits — read and write MCU configuration settings.
• Full Erase — erase the MCU memory.
• Partial Erase — erase selected memory areas as supported by the programming software.

USB Interface

The programmer uses a USB interface and appears to the computer as a CDC COM port. This makes it convenient for custom programming software and avoids the need for a dedicated USB-to-ICP driver.

Applications

• N76E003 development
• Firmware development and debugging
• Bootloader programming
• DIY N76E003 projects

Notes

• Designed specifically around the N76E003 ICP programming interface.
• The target board must provide access to ICPDA, ICPCK, VCC, and GND.
• Target voltage and wiring should be compatible with the N76E003 and programmer.
• USB cable and target N76E003 board are not included unless specified separately.
