O Clock
High-speed system clock … Selected from the following three sources
- Ceramic/crystal resonator:
2 to 10 MHz (Standard product, (A) grade product)
2 to 8 MHz ((A2) grade product)
- External clock:
2 to 10 MHz (Standard product, (A) grade product)
2 to 8 MHz ((A2) grade product)
- High-speed internal oscillator:
8 MHz
±3% (10 to +70°C),
8 MHz
±5% (Standard product, (A) grade product: 40 to +85°C, (A2)
grade product:
40 to +125°C)
Low-speed internal oscillator 240 kHz (TYP.) … Watchdog timer, timer clock in intermittent operation
O I/O ports: 14 (CMOS I/O: 13, CMOS input: 1)
O Timer: 3 channels
16-bit timer/event counter: 1 channel … Timer output × 1, capture input × 2
8-bit timer:
1 channel … PWM output
× 1
Watchdog timer:
1 channel … Operable with low-speed internal oscillation clock
O On-chip power-on-clear (POC) circuit (A reset is automatically generated when the voltage drops to 2.1 V (TYP.)
or below)
O 10-bit resolution A/D converter (
μPD78F921x only): 4 channels
O On-chip low voltage detector (LVI) circuit (An interrupt/reset (selectable) is generated when the detection voltage
is reached)
Detection voltage: Selectable from ten levels between 2.35 and 4.3 V
O Single-power-supply flash memory
Flash self programming enabled
Software protection function: Protected from outside party copying (no flash reading command)
Time required for writing by dedicated flash memory programmer: Approximately 3 seconds (4 KB)
Flash programming on mass production lines supported
O Safety function
Watchdog timer operated by clock independent from CPU
… A hang-up can be detected even if the system clock stops
Supply voltage drop detectable by LVI
… Appropriate processing can be executed before the supply voltage drops below the operation voltage
Equipped with option byte function
… Important system operation settings set in hardware
O Assembler and C language supported
