Nuvoton Technology Provides the ISP Programmer for Flash-based 8051 MCU

Hsinchu, Taiwan – Nov/9/2009 – Nuvoton Technology Corp. launches a new low-cost ISP(In-System Programming) tool, 8051 ISP Programmer, for the Flash-based 8051 MCU products. Nuvoton Flash-based 8051 MCU has the built-in advanced ISP (In-System Programming) function. Through the ISP interface, users can re-program the MCU’s program memory without removing the mounted MCU chip from the fabricated product. It will be more easy for users updating the MCU’s firmware.

Nuvoton (formerly known as the logic product business group of Winbond) had dedicated 15 years to the development of 8051 MCU, and provides customers a great diversity of 8051 MCU products. Its quality, reliability and stability have been greatly appreciated and obtained an excellent reputation. Today Nuvoton has become one of the largest suppliers of 8051 MCU products in the Greater China area.

The new 8051 ISP Programmer has two operation modes: on -line mode and off-line Mode. Under on-line mode, users can plug it into PC’s USB port and directly update the program memory of the 8051 MCU. In addition, owing to its built-in non-volatile storage, users can also download the code data into the ISP Programmer for the usage under off-line mode. Under off-line mode, since the code data were previously downloaded, users can also directly update the program memory of the 8051 MCU without PC’s intervention.

The on-line mode is suitable for engineering development stage while the off-line mode is especially for production stage or the circumstances without a PC. Using several ISP Programmers previously downloaded with different code data, the product engineer can integrate testing and final programming into the production process. Thus the flexibility in testing and production is greatly improved.

With the new 8051 ISP Programmer, users don’t need more complex and expensive universal programmers to program Nuvoton’s 8051 MCU products. More information about 8051 MCU and the ISP Programmer, please visit or contact our sales.
