Features

KV4x

  • 168 MHz Cortex-M4 core with DSP, floating point unit – improves performance in math-intensive applications (e.g., processing of sensorless FOC (field oriented control) algorithms)
  • 128-bit wide flash interface with a cache to minimize the number of wait states while executing fast control loops
  • 2x 12-bit, 16-channel ADCs with PGAs – 4.1 MSPS ideal for digital power conversion or for motor control applications
  • Up to 12 channel eFlexPWM – up to 312ps resolution for demanding digital power conversion applications
  • Up to 2 x 8-channel and 1 x 2-channel programmable FlexTimers – high-accuracy PWM generation with integrated power factor correction or speed sensor decoder (incremental decoder/hall sensor)
  • Quadrature encoder/decoder
