The MC56F82xxx DSP MCU family offers outstanding power consumption at runtime with exceptional performance, precision, and control.

  • Targets high-efficiency digital power conversion (MC56F827xx) and advanced motor control (MC56F826xx) applications
  • Delivers half the power with twice the performance for energy-efficient applications
  • Reduces costs through higher switching frequencies
  • Increases system safety by restricting user code from accessing key memory locations and peripherals reserved for supervisor access
  • Enables compact PCB design for space-constrained applications while still providing the precision and control needed

Features

  • Low-power operation enables higher system efficiency due to lower power losses
  • 5 mm x 5 mm package option enables compact PCB design for space-constrained applications while still providing the precision and control needed
  • 50/100 MHz 32-bit core provides math capabilities needed for advanced power efficiency and motor control applications
  • Single-cycle math computations, fractional arithmetic support, and parallel moves improve performance, driving tighter and faster control loops
  • High-resolution PWM with 312 pico-second resolution enables higher switching frequencies, reducing cost and increasing efficiency
  • Two 12-bit high-speed (HS) ADCs with up to 1.25 MSPS resolution improves system accuracy by reducing jitter on input values
  • 32 KB to 64 KB flash memory provides scalability needed for key digital power and motor control applications
  • Pin-to-pin compatible with the MC56F84xxx and MC56F824x/5x families for performance and peripheral scalability
  • 5 volt-tolerant I/O provides design flexibility and system cost reduction
  • Direct memory access (DMA) controller reduces core interruption, increasing performance
  • Four analog comparators with integrated 6-bit DACs speed system event identification and emergency shutdown of the PWM outputs
  • Memory protection capability increases system safety by restricting user code from accessing key memory locations and peripherals reserved for supervisor access
