GENERAL RELEASE SPECIFICATION
MC68HC05J5
ELECTRICAL SPECIFICATIONS
MOTOROLA
REV 1.1
10-3
NOTES:
1.
All values shown reflect average measurements.
2.
Typical values at midpoint of voltage range, 25
°C only.
3.
Wait IDD: Only timer system (MFT) active.
4.
Run (Operating) IDD, Wait IDD: Measured using external square wave clock source to OSC1 (fOSC = 2.0 MHz), all inputs 0.2 Vdc
from rail; no dc loads, less than 50pF on all outputs, CL = 20 pF on OSC2/R.
5.
Wait, Stop IDD: All ports configured as inputs, VIL = 0.2 Vdc, VIH = VDD–0.2 Vdc.
6.
Stop IDD measured with OSC1 = VSS.
7.
Wait IDD is affected linearly by the OSC2/R capacitance.
8.
TA = 0°C to +40°C.
9.
Minimum and maximum values of both VT+ and VT– will be determined after enough characterization has been done. Input voltage
level on PA6 or PA7 higher than 2.4V is guaranteed to be recognized as a logical one and as a logic zero if lower than 0.8V.
10. PA6 and PA7 pull-up resistor values are specified under the condition that pin voltage ranges from 0V to 2.4V.
10.4
CONTROL TIMING
(VDD = 5.0 Vdc ±10%, VSS = 0 VDC, TA = –40°C to +85°C, unless otherwise noted)
NOTES:
1.
The minimum period tILIL or tIHIH should not be less than the number of cycles it takes to execute the interrupt service routine plus
19 tCYC.
2.
Effects of processing, temperature, and supply voltage (excluding tolerances of external R and C).
3.
RC oscillator: Typical center frequency is 4.0 MHz. For the specified range of the operating center frequency from 3.8MHz (min)
to 4.2 MHz (max), the frequency tolerance is guaranteed to be no more than
±15% under the conditions that V
DD = 5.0 VDC ±10%,
TA = 0°C to +40°C and the tolerance of the external R is at most ±1%.
