I'm using the A version of this part because it accepts a crystal from 1 to 8Mhz, whereasa the "non A" accepts a 32KHz crystal. I'm having a problem where the 8 MHz crystal is not oscillationg (I'm using 20 pF on each leg to ground). I build 6-boards. the first two I put together (using samples from freescale) work. The other 4-boards (micros were purchased) only 1 boards is oscillationg. The other 3, the circuit is not working. I am not using the phase lock loop. I also tried a 4 and an 8 Mhz resonator.
I replaced the micro on one of the boards and still the crystal is not oscillating. The boards work find if I used an external oscillator. This should be the simplest part of the total design. Could the parts be mismarked and I actually received the "Non A" device.
Any suggestion would be greatly appreciated.
