UPD78F071x

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.

 

Main Solutions

Key Features:

  • Operating voltage: VDD = 4.0 to 5.5 V
  • Max. frequency: 5 MHz
  • ROM capacities: 8 to 32 KB flash mmeory
  • RAM capacities: 768 to 1024 bytes
  • Package:
    • 30-pin plastic SSOP (7.62 mm (300)) : μPD78F0711, 78F0712
