10.2 RECOMMENDED OPERATING CONDITIONS
10.3 DC ELECTRICAL CHARACTERISTICS
Recommended operating conditions with TA=-40 to +125
oC, V
DD-VSS=5V unless otherwise specified.
10.4 GENERAL TIMING CHARACTERISTICS
Notes:
1) Unless otherwise specified, typical data is based on TA=25°C and VDD-VSS=5V. This data is provided only as design
guidelines and is not tested.
2) Fixed frequencies required to obtain 4MHz for the motor control peripheral.
3) CPU running with memory access, all I/O pins in input mode with a static value at VDD or VSS, all peripherals switched
off; clock input (OSC2) driven by external square wave.
4) All I/O pins in input mode with a static value at VDD or VSS, all peripherals switched off; clock input (OSC2) driven by
external square wave.
5) All I/O pins in input mode with a static value at VDD or VSS.
6) Data based on characterization results, not tested in production.
7)
t
INST is the number of tCPU to finish the current instruction execution.
