Interface description:

SWD interface four wires, VCC(=3.3V),GND,SWDIO(=TMS=DIO),SWCLK(=TCK=CLK)

Product introduction

It is usually designed to be placed on the evaluation board (" on-board ") of major companies, which is why the suffix is "OB". This set of simulation download debugging device named "ARM-OB" has USB communication function, can communicate with PC, the other end through SWD /JTAG way to communicate with supported devices, to complete the debugging simulation download debugging task. Compared with the original OB debugger, our ARM OB simulation debugger lacks JTAG interface and only retains SWD interface, so as to debug and download the MCU of many companies using ARM kernel.

Supported kernels

All with SWD interface ARM7911, Cortex-M0M1M2M3M4A5A8A9 and other embedded MCU series.

Support MCU producer

ST(Stmicroelectronics), Freecale(Freescale), Nuvoton (New Tang), NXP(NXP), TI(Texas Instruments)

Cypress, Atmel, Analog, Fujitsu, Toshiba

Energy Micro, etc.

The connection method

SWD mode

Function and performance

Programming function: can burn FLASH ROM, EEPROM, AFR, etc.

Simulation function: Support full speed running single step debugging, breakpoint debugging and other debugging methods, can view IO status, variable data, etc.

Programming performance: USB2.0 interface, SWD download, download speed!

Simulation performance: USB2.0 interface for simulation debugging, single step debugging, breakpoint debugging, fast response speed!

Product characteristics

1, simplified interface, using 4-wire SWD interface: vcc, swdio, swclk, gnd, can download simulation at high speed.

2, compatible with the traditional V8 emulator, the function is completely consistent.

3, the use of universal micro USB interface, easy to use (common Android phone interface).

4, support 3.3V output, large output 300MAcurrent, convenient for users to debug and download the target board.

5, the new on-board self-recovery fuse, effective short circuit protection, debugging more safe.

6, ESD protection device, more stable.

7, transparent heat shrink tube packaging.

8, the firmware is stable, can be automatically upgraded, there will be no firmware damage(full-function v8 has firmware problems).

9, U disk size, convenient project is carried on business trips.
