 Low power consumption (V
DD = 5.0 V)
 Internal high-speed oscillator operation mode: 350
 A (TYP.) (fCPU = 1 MHz operation)
 STOP mode: 0.58  A (TYP.) (fIL = 30 kHz operation)
 Clock
 High-speed system clock … Selected from the following four sources
- Ceramic/crystal oscillator: 1 to 10 MHz
Note
- External clock: 1 to 10 MHz
Note
- Internal high-speed oscillator: 4 MHz ± 2 % (–20 to +70C)
Note
, or 8 MHz ± 3 %(–40 to +85C)
- Clock for 16-bit timers X0 and X1: 40 MHz (TYP.) (when using PLL)
 Internal low-speed oscillator 30 kHz ± 10 % … Watchdog timer, timer clock in intermittent operation
Note When using a 4 MHz clock, operation at 20 MHz is possible by using PLL.
 Timer
 16-bit timer X … PWM output (40 MHz (MAX.) clock operation), operation in conjunction with an
external signal, synchronous output of up to four channels, A/D conversion trigger
generation
 16-bit timer/event counter … PPG output, capture input, external event counter input
 8-bit timer H1 … PWM output, operable with low-speed internal oscillation clock
 8-bit timer/event counter 51 … External event counter input
 Watchdog timer … Operable with low-speed internal oscillation clock
