Product Info

This BDM pod supports most HC12 and S12 chips, and is compatible with both 6-pin and 10-pin target BDM connectors. It requires no external power, as it receives power from your target board. It is compatible with 5V targets.

Features:

  • low-cost BDM pod for all HC12 and S12 targets (not including S12X)
  • works only with 5-Volt targets
  • use D-Bug12 commands to interact with target MCU
  • supports hardware and software breakpoints in target
  • RS232 interface to PC (or any platform with terminal emulation capability)
  • 10-pin ribbon cable (superset of standard 6-pin BDM pinout), compatible with all Adapt12 and Adapt9S12 boards, as well as most other vendors' boards
  • no power supply required-- draws power from target board
  • housed in a robust plastic enclosure for maximum reliability
  • includes power and activity indicator LEDs
  • based on a 9S12DG128 MCU running D-Bug12 version 4.0
  • supports baud rates up to 115K (default is 9600 baud)
  • compatible with NoICE12 debugger
  • requires standard 9-pin serial extension cable (not included)

Chips supported:

68HC812A4, 68HC912B32, 68HC912BC32, 68HC912D60/A, 68HC912DA128/A, 68HC912DG128/A, 68HC912DT128/A, and all 9S12 derivatives except X and Z. Can communicate with 9S12X chips, but does not support Flash erase/program nor the XGATE co-processor. Our USBDMLT pod is the recommended alternative for working with 9S12X and S12Z MCUs.

NOTE: if you need USB connectivity, you may wish to consider MicroBDM12LXU5 instead

Product Details

Here's how to use MicroBDM12LX5:

Just connect the supplied ribbon cable to the target board's "BDM IN" connector. The target board could be any Adapt12-family board, or any other 'HC12 or 9S12 board that has a 6- or 10-pin BDM interface connector. Just be sure to line up the pin 1 indicator with pin 1 on the BDM connector. The host for the BDM Pod can be any type of computer running a terminal program. The BDM pod will receive its 5V operating power from the target board through the ribbon cable. A couple of suggested Windows terminal programs: TeraTermPro, MiniIDE, Hyperterminal. For details on using other terminal programs with D-Bug12, refer to the D-Bug12 Manual.

The big advantage of using a BDM pod is that it frees up all of the target board's memory for your application, while still offering you debugging capability. You can examine memory and registers, disassemble a memory range, set breakpoints, and do tracing in the target board's on-chip memory, among other things.

What's inside the box:

MicroBDM12LX5 is a minimal 9S12 board, running D-Bug12 v4.0. It consists of the MCU, a crystal, an RS232 interface circuit, and a few miscellaneous components, all mounted on a small board less than 2 inches square. A 10-pin ribbon cable is attached to one edge, and a 9-pin D-sub connector is on the opposite edge, and the whole assembly is housed in a small plastic box. Any 9-pin serial extension cable can be used to connect to the host serial port.

Firmware Updates:

If D-Bug12 ever needs to be updated, it can be done using another BDM pod. By opening the box, applying a DC voltage (5 to 9V, nominal) to the power connector on the circuit board, and moving two jumpers to make the ribbon cable function as BDM IN, the board becomes a target, and Flash can be erased and re-programmed as needed.
