User's Guide

1. Introduction

The Freedom development board is a set of software
and hardware tools for evaluation and development. It is
ideal for rapid prototyping of microcontroller-based
applications. The Freedom KV11 hardware,
FRDMKV11Z, is a simple, yet sophisticated design
featuring a Kinetis V series microcontroller, built on the
ARM Cortex -M0+ core, and a perfect solution for
® ®
BLDC and PMSM motor control applications. FRDM-
KV11Z can be used to evaluate the KV1x Kinetis V
series devices. It is based on the MKV11Z128VLF7
microcontroller, running up to 75MHz with hardware
square root and divide capability and featuring dual 16-
bit analog-to-digital controllers (ADCs) sampling at up
to 1.2 mega samples per second (MS/s) in 12-bit mode,
multiple motor control timers, 128KB of flash and
16KB of RAM memories and CAN interface. It is
supported by a comprehensive enablement suite from
NXP and its third-party resources including reference
designs, software libraries, and motor configuration
tools. The FRDM-KV10Z hardware is form-factor
compatible with the Arduino® R3 pin layout, providing
a broad range of expansion board options. Board
embeds a 6-axis digital sensor, combining
accelerometer and magnetometer, an analog thermistor,
a RGB LED and two user push-buttons. The
FRDMKV11Z platform includes the OpenSDA, the
NXP open-source hardware for embedded serial and
debug adapter, programmed with an open-source
bootloader. This circuit offers several options for serial
communication, flash programming, and run-control
