High Speed J-Link JLINK V8 Stm32 J-Link V9 USB JTAG Emulator Debugger J-Link V8 Emulator

Differences between JLink V9 and Jlink v8:

Speeds: V8 supports up to 10M (JTAG debugging mode)/4M (SDW debugging mode), while Jlink V9 supports up to 20M (JTAG debugging mode)/15M (SDW debugging mode).

Stability: V9's drive IC has the ability of voltage adaptation, which can automatically adapt to the cpu voltage of the target board when the wiring is correct. Both 1.8-5.5V CPUs can be debugged, while V8 can only debug 3.3V CPUs, and the stability of debugging 5v cpu is poor.

Jlink V8 is easy to lose its firmware. Many V8s have hung up, and need to rewrite the firmware. Ordinary users can only let it be, while V9 does not.

V8 no longer support some of the latest CPU , while V9 supports almost all ARM CPU.

Features of JLINK V9:

The main control chip is STM32F205, without losing the firmware, and the hardware has been upgraded to the latest version of V9.2

It can provide 3.3V voltage 0.8A current for the development board (The second pin)

Support standard JTAG interface and 2-wire SWD debugging interface. The speed can reach 20M (JTAG)/15M (SWD) per second.

It supports debugging of all ARM chips, MDK or IAR, and compilation environment IDE supported by other standard JLinks.

Original firmware, full automatic firmware upgrade.
