Description
The µPD78F071x are products of a series developed for motor applications performing 2-chip control and which specializes in motor control. They incorporate a 10-bit inverter control timer that enables PWM output with dead time and a Hi-Z output controller that controls the high impedance (Hi-Z) of 6- phase PWM for fail-safe.
- Minimum instruction execution time can be changed from high speed (0.1 µs: @ 20 MHz operation with) X1 input clock) to low-speed (8.33 µs: @ 240 kHz operation with internal low-speed oscillation clock)
- On-chip internal high-speed oscillator (8 MHz (TYP.))
- General-purpose register: 8 bits × 32 registers (8 bits × 8 registers × 4 banks)
- On-chip multiplier/divider
- 16 bits × 16 bits = 32 bits (multiplication)
- 32 bits ÷ 16 bits = 32 bits, 16 bits remainder (division)
- On-chip single-power-supply flash memory
- Self-programming
- On-chip debug function
- On-chip power-on-clear (POC) circuit and low-voltage detector (LVI)
- Short startup is possible via the CPU default start using the internal low-speed oscillator
- On-chip watchdog timer (operable with internal low-speed oscillation clock)
- On-chip real-time output ports
- I/O ports: 15
- Timer: 5 channels
- Serial interface: 1 channel (UART: 1 channel)
- 10-bit resolution A/D converter: 4 channels
- Supply voltage: VDD = 4.0 to 5.5 V
- Operating ambient temperature: TA = -40 to +85°C
