TDK Corporation has added the Micronas embedded motor controller with the HVC 4420F to its portfolio. It has an extended flash memory to 64 KB and SRAM to 4 KB, conducive for small brush-type, stepper, or brushless motor drives and meets the latest demands of the automotive industry.

The HVC 4420F runs on a 32-bit CPU core (ARM Cortex-M3) with 64 kB flash memory and includes:

• timers/counters
• interrupt controllers
• multichannel ADC
• SPI
• enhanced PWMs with diagnosis functions

The HVC 4420F’s high processing power operates complex motor control algorithms including Space Vector Modulation (SVM) for everlasting magnet synchronous motors (PMSM), six-step commutation with sensor feedback or sensorless control, in addition to various stepper configurations.

The HVC 4420F grants the option to include production-ready and highly flexible, parameterizable firmware with advanced communication, monitoring and power management functions (ASIL A ready) and a configuration tool.
