How does one figure out what mask set goes with what part number??? We use A256 and require at least the 2K79X mask because of comm port issues. We put a...

Hi Rod, The 3L91N or 4L91N mask-sets should be good for you, as a replacement for the discontinued 2K79X mask-set. I believe these mask-sets fix all the...

Hello, I'm trying to drive a led with the HC12, but the output current of the led is only 10microA, and i did not find a led that can work with such a small...
Use the pins that are specified LED drive capable, typically 20mA or so on the LED pins. Unfortunately, in the interest of low power consumption, Freescale...
Jeff, We have hundreds of HCS12 full-emulators, plus even a larger number of HCS12 BDMs used by customers - all with other HC12 compilers. As far as I am...

Add a driver. Around here, the prefered driver is an MOSFET. With an NMOS FET, the gate runs to the HC12, the source to ground, and the drain to the LED and ...
