silly question 2. "HIGH voltage for 9s12dg128" - toma...@hotmail.com - Nov 21 7:09:21 2008
Im sorry to ask this, what is the voltage range for Logic 1 and Logic 0 for this device.
Is it;
1 = 2.2V to 5V
0 = 0V to 0.8V

Re: silly question 2. "HIGH voltage for 9s12dg128" - Edward Karpicz - Nov 21 7:30:29 2008
No, from MC9S12DT128 Device User Guide, Table A-6 5V I/O characteristics:
Input High Voltage VIH min = 0.65*VDD5
Input Low Voltage VIL max = 0.35*VDD5
VDD5 is 5V, so guaranteed '0' is <=1.75V, guaranteed '1' is >=3.25V
1 = 3.25V to 5V
0 = 0V to 1.75V
