Kinetis V series microcontrollers (MCUs) combine the performance and precision needed for real-time control applications, such as motor control and power conversion, with the ease-of-use of ARM Cortex -M processor combined with the performance, peripheral set, enablement, and scalability of the Kinetis 32-bit MCU portfolio. The Kinetis KV5x family of MCUs is a highperformance solution offering exceptional precision, sensing, and control for some of the most demanding applications in motor control and power conversion. Built upon the ARM Cortex-M7 core running at 240 MHz with single precision floating point unit, it features advanced high-speed and high-accuracy peripherals such as high-resolution pulse width modulation (PWM) with 312-picosecond resolution, four 12-bit analog-to-digital converters (ADCs) sampling at 5 mega samples per second (MSPS), a total of 44 PWM channels for support of multi-motor systems with PFC, three FlexCAN modules and optional Ethernet communications. The KV5x is supported by a comprehensive enablement suite from Freescale and third-party resources including reference designs, software libraries, and motor configuration tools.
- High-performance 240 MHz ARM Cortex-M7 core with a high level of analog and digital integration targeted at real-time control applications.
- Utilizes the ARM Cortex-M7, which is ideally suited for real-time control applications.
- Up to 1 MB of Flash and 256 KB of RAM, 16 KB of instruction cache and 8 KB of data cache. 256 KB of RAM includes 64 KB of ITCM RAM, ensuring maximum CPU performance of fast control loops with minimal latency.
- Wide Flash interface supports secure and fast access to safety-critical control parameters, minimizing CPU wait states.
- The four ADC blocks, two banks of two, sampling at 5 MSPS with dual sample and hold circuitry, can capture current and voltage for two motors simultaneously, giving true independent dual motor control, or provide the ability to read all three currents / voltages simultaneously, providing the most accurate results.
- Ethernet option with true random number generator and cryptographic unit provide a low-cost integrated connectivity solution.
- The multiple instantiations of timer blocks provide a vast array of timers (44 channels), simplifying the complex task of advanced motor control.
- The two eFlexPWM blocks provide four independent time bases per module with a highly flexible configuration that easily supports motor-control and power-control topologies.
- A single eFlexPWM block featuring 12 channels with nano-edge capability, providing up to 312- picosecond resolution on pulse width and frequency modulation.
- An inter-peripheral cross bar, with And or Invert logic, provides a highly-flexible connection fabric between peripherals that supports simplified control topology implementation.
