Low power consumption (V
• Internal high-speed oscillation mode:
• STOP mode:
• Subsystem clock and HALT mode:
Clock
• High-speed system clock … Selected from the following three sources
• Low-speed system oscillator
• Subsystem clock:
Power-on-clear (POC) circuit
Low-voltage detector (LVI) (An interrupt/reset (selectable) is generated when the detection voltage is reached))
• Detection voltage: Selectable from sixteen levels between 1.91 and 4.22 V
Single-power-supply flash memory
• Flash self programming enabled
• Software protection function: Protected from outside party copying (no flash reading command)
Safety function
• Watchdog timer operated by clock independent from CPU
• Supply voltage drop detectable by LVI
• Equipped with option byte function
- Ceramic/crystal oscillator:
- External clock:
- Internal high-speed oscillator: 4 MHz ± 2 % (–20 to +70°C), or 8 MHz ± 3 %(–40 to +85°C)
… A hang-up can be detected even if the system clock stops
… Appropriate processing can be executed before the supply voltage drops below the operation voltage
… Important system operation settings set in hardware
