HCS12 T-Board

Hands-on HCS12!

Freescale's amazing HCS12 Controller Family is an upgrade from the existing 16-bit product line HC12. Compared to the HC12, the new types are faster and more flexible, while the programming model and the instruction set remain the same.

HCS12 Microcontrollers are manufactured with a state-of-the-art 0.25µm process. With this advanced technology, larger memory areas and a rich set of peripheral modules fit on smaller die sizes.

The MCU MC9S12DP512 is the current flag ship of the HCS12 fleet. Special highlights are: 25MHz bus clock rate, 512KB on-chip Flash memory, 14KB RAM and five CAN-Modules. For additional features see the overview on the right.

HCS12 T-Board as EVB

On the HCS12 T-Board there are four header connectors placed around the MCU. All MCU signals are accessible here. Pin-out and mechanical arrangement are compatible to the DP256EVB (Barracuda Evaluation Board) from Freescale (formerly: Motorola).

HCS12 T-Board as Training Board

The compact HCS12 T-Board is equipped with a large number of peripheral functions, which make it easy to do hands-on training and perform real-life tests with the MC9S12DP512 microcontroller. Therefore, the HCS12 T-Board is ideally suited for Evaluation, Training and Education!

TwinPEEKs Monitor Program

Each HCS12 T-Board is equipped with a special version of our TwinPEEKs monitor software, which allows easy download and programming of Flash Memory and EEPROM - without needing additional hardware tools!

The monitor code resides in a write-protected Flash boot block (only 4KB). It can not be erased unintentionally.

The assembly language source code of TwinPEEKs is available on request.

S12X T-Board

S12X is the name of the latest top-branch of Freescale's 16-bit microcontroller family. Derived from the current HCS12-line (which will be continued and offered in parallel by Freescale), the S12X delivers additional performance for demanding applications, e.g. for the automotive area. Higher clock frequency, optimized instruction set, more memory and the new DMA co-processor XGATE are key components of the new S12X technology.

Please note: the S12X board version is currently offered as a hardware item solely, i.e. delivery is without any additional software!
