R8C/LA3A Group, R8C/LA5A Group, R8C/LA6A Group, R8C/LA8A Group 5. Electrical Characteristics
5.2.2 Recommended Operating Conditions
Notes:
1. The average output current indicates the average value of current measured during 100 ms.
2. This applies when the drive capacity of the output transistor is set to High by registers P7DRR and P8DRR. When the drive capacity
is set to Low, the value of any other pin applies.
3. fOCO20M can be used as the count source for timer RC in the range of VCC = 2.7 V to 5.5V.
Table 5.31 Recommended Operating Conditions
(VCC = 1.8 to 5.5 V and Topr = −20 to 85°C (N version)/ −40 to 85°C (D version), unless
otherwise specified.)
