In this product card write, that MC3PHACVDWE are 8BIT MCU, 8K FLASH OTP. In datasheet i dont found any informations or schematic about MCU. Can you any post schematic or diagram? Or send link with information about MCU include in this part? Very thanks
已解决! 转到解答。
The MC3PHACVDWE is no longer manufactured. and the internal 8 bit device never was sold as a simple MCU.
Now if you need an 8 bit device for motor control please check the MC9S08MP family

Dear Worfvx,
Sorry for my late answer, the MC3PHAC is really a preprogrammed HC908MR8 device, I´ve got the CW complete project that assembles (yep, .ASM) flawlessly in CW 6.3 running on my WIN10 64-bit (Tks Rod!). There are lots of information on this like An2202, An2988, DRM006 DRM019. Motorola/Freescale really provided excellent documentation.

Maybe you could still use this code - or parts of it - with the newer S08.
