NU-LINK-GANG USER MANUAL
1 GENERAL DESCRIPTION
The Nu-Link-Gang programmer is the new generation four-chip gang programmer, supports all
Nuvoton NuMicro®Family and 8051 1T series and packages. The Nu-Link-Gang provides flexible
programming setting, which is designed especially for mass-production. It supports four different chips
with individual firmware image file programming functionality, 3 options of programming voltage, and
off-line programming four chips simultaneously or individually. The Nu-Link-Gang can also be
connected to a automatic IC programming system. Overall, the Nu-Link-Gang offers more flexibility
and high efficiency than what usual programmers offer for mass-production.
The Nu-Link-Gang programmer is easy to use. User first loads the programming firmware image file
through ICP programming tool on PC into the programmer, then use only one botton to start the off-
line programming process. The LCD display on the Nu-Link-Gang shows the detail of IC’s part
number, programming times, programming voltage, error message, and etc. User can connect the Nu-
Link-Gang programmer and target chips by using a automatic IC programming system, Nuvoton ICP
Gang Adapters or customize adapter boards. Different ICs or different packages use different Nuvoton
ICP Gang Adapters.
