Introduction

In the world of microcontrollers, programming and updating the firmware can be a complex and time-consuming process. However, with the introduction of In-System Programming (ISP), users can now update the program memory of their microcontrollers without having to remove them from the actual end product. In this article, we will delve into the world of NuMicro ISP programming tools and explore their features, benefits, and applications.

What is ISP?

ISP, or In-System Programming, is a technology that allows users to update the program memory of their microcontrollers without having to remove them from the actual end product. This is made possible through the use of a host PC's USB or COM port, which connects to the microcontroller via a programming cable. The ISP solution provided by Nuvoton enables users to update the MCU's APROM and DataFlash, as well as the configuration bits.

How Does ISP Work?

The ISP process involves several steps:

Programming: The user programs the Nuvoton standard ISP code into the LDROM (Low-Density ROM) of the microcontroller.
Configuration: The user configures the configuration bit "CBS" as Boot from LDROM.
ISP Connection: The user connects the microcontroller to the host PC via a programming cable.
ISP Programming: The user uses the ISP programming tool to update the MCU's APROM and DataFlash, as well as the configuration bits.
