MC68HC08JT8
NOTES:
1. VDD = 2.0 to 3.6 Vdc, VSS = 0 Vdc, TA = TL to TH, unless otherwise noted.
2. Typical values reflect average measurements at 3V, 25 °C only.
3. In LDD mode, the specified IOL is achieved when the external pullup voltage is equal to or higher than the voltage:
VOL + voltage dropped across LED.
4. Run (operating) IDD measured using external square wave clock source (fXCLK = 6 MHz). All inputs 0.2 V from rail. No dc
loads. Less than 100 pF on all outputs. CL = 20 pF on OSC2. All ports configured as inputs. OSC2 capacitance linearly
affects run IDD. Measured with all modules enabled.
5. Wait IDD measured using external square wave clock source (fXCLK = 6 MHz). All inputs 0.2 V from rail. No dc loads. Less
than 100 pF on all outputs. CL = 20 pF on OSC2. All ports configured as inputs. OSC2 capacitance linearly affects wait IDD.
6. Stop IDD measured with OSC1 grounded; no port pins sourcing current.
7. Maximum is highest voltage that POR is guaranteed.
