Table 20 Recommended operating conditions (5) (VCC = 2.2 to 5.5 V, Ta = –20 to 85°C, unless otherwise noted)
Notes1: When the oscillation frequency has a duty cycle of 50%.
2: When using the microcomputer in low-speed mode, make sure that the sub-clock input oscillation frequency on condition that f(X
CIN) < f(XIN)/3.
