Virtual serial port
A serial port connection is available between the OpenSDA MCU and pins PTB16/UART0_RX and
PTB17/UART0_TX. A voltage level translator is on-board to ensure signal integrity in case the KV11
MCU and the OpenSDA MCU are at different voltage levels. To determine which COM port number
Figure 9. Determining COM number in Windows Device Manager
Open the Device Manager by right-mouse clicking on Computer and select Manage. Then select Device
Manager and open the Ports (COM & LPT) drop-down.
4. Microcontroller
The Kinetis KV1x family of microcontrollers is a cost optimized solution specifically designed for
motor control applications. Built upon the ARM® Cortex®-M0+ core running at 75 MHz, it is the
fastest ARM Cortex-M0+ MCU in the market. With hardware square root and divide capability, it
delivers a 27% increase in performance in math intensive applications versus comparable MCUs,
allowing it to target BLDC as well as more computationally demanding PMSM motors. Additional
features include:
• 128 KB of flash memory and optional CAN
• dual 16-bit analog-to-digital controllers with 835 ns conversion time in 12-bit mode
• Programmable delay block
Kinetis KV1x MCUs are offered in 64 LQFP, 48 LQFP, 32 LQFP and 32 QFN packages and comes
with a comprehensive enablement suite from NXP and third-parties that include reference designs,
software solutions and tools making motor control simple.
