Dimmer with MC68HC908QT4CP

hajsenberg22 — Sun, 24 Aug 2025 19:37:53 GMT

Hi all,

Following this article AN2839: Implementing a Lamp Dimmer with an HC908Q Family MCU

I got MC68HC908QT4CP.

I am looking for programmator and application to support it, I got the code from the nxp article above.

Looking at this forum, I could use CodeWarrior Dev Studio v11 or CodeWarrior Classic 6.3?

What else I would need to get that code into chip: USBMULTILINK08, M68CPA08P40B56, anything else? I have ALL-07 but don't think it supports it.

Thanks
hajsenberg

Hi @hajsenberg22,

For HC08QT4, we recommend using CodeWarrior 6.3 as IDE.

CodeWarrior® for Microcontrollers-Classic IDE | NXP Semiconductors

For programmer you can take a look to PEmicro Cyclone FX programmer which still support HC08 devices.

HI Pablo, thank you for the message.

Today is relatively hard to find HC908 & programmer, and I was wondering is there any other microchip from NXP which could work in a same way & with same code from that datasheet -> with some other more popular programmer & new versions of CodeWarrior?

Thanks
Leon

Hi @hajsenberg22,

I apologize for the inconvenience this may cause you, but the MC68HC908QT4CP does not have a direct replacement.

If you want to stay within the 8-bit family, I recommend exploring the S08 MCU portfolio, however, they are not software compatible with the MC68HC908QT4CP. Specifically, the S08PB series is a good starting point, as it offers evaluation and development boards.

8-Bit S08 MCUs | NXP Semiconductors

S08PB16 and S08PLS Evaluation Kit | NXP Semiconductors

The S08 MCUs use CodeWarrior 11.1 as the development IDE. You can program them using various tools such as:

Universal Multilink Development Interface | NXP Semiconductors

PEmicro Cyclone FX programmer | NXP Semiconductors

Universal Multilink FX High-Speed Development Interface | NXP Semiconductors

PEmicro Cyclone programmer | NXP Semiconductors

If you use the Evaluation Kit, it comes with OSBDM, which allows you to flash and debug the MCU without needing an external debug tool.

Best Regards,

Pablo
