Virtual serial port
A serial port connection is available between the OpenSDA MCU and pins PTA1 and PTA2 of the
KV31 MCU.
4. Microcontroller
The FRDM-KV31F features the MKV31F512VLL12 MCU. The KV31 MCU family is a highly scalable
member of the Kinetis V series and provides a high-performance, cost-competitive motor control
solution. Built on the ARM Cortex-M4 core running at 120 MHz, combined with floating point and DSP
capability, this is implemented in the 100-pin LQFP package. The following table describes some of the
features of the MKV31F512VLL12 MCU.
