FRDM-K64F Freedom Module User ’ s Guide

1 Introduction

The Freescale Freedom development platform is
a set of software and hardware tools for
evaluation and development. It is ideal for rapid
prototyping of microcontroller-based
applications. The Freescale Freedom K64
hardware, FRDM-K64F, is a simple, yet
sophisticated design featuring a Kinetis K series
microcontroller, built on the ARM®
Cortex®-M4 core.

FRDM-K64F can be used to evaluate the K64,
K63, and K24 Kinetis K series devices. It
features the MK64FN1M0VLL12 MCU, which
boast the maximum operation frequency of 120
MHz, 1 MB of flash, 256 KB RAM, a full-speed
USB controller, Ethernet controller, secure
digital host controller, and analog and digital
peripherals. The FRDM-K64F hardware is
form-factor compatible with the ArduinoTM R3
pin layout, providing a broad range of expansion
board options. The onboard interface includes a
six-axis digital accelerometer & magnetometer,
RGB LED, SDHC, add-on Bluetooth module,
add-on RF module, and Ethernet.

2 FRDM-K64F hardware overview

The features of the FRDM-K64F hardware are as follows:

• MK64FN1M0VLL12 MCU (120 MHz, 1 MB flash memory, 256 KB RAM, low-power, crystal-

less USB, and 100 LQFP)

• Dual role USB interface with micro-B USB connector

• RGB LED

• FXOS8700CQ – accelerometer and magnetometer

• Two user push buttons

• Flexible power supply option – OpenSDAv2 USB, K64 USB, and external source

• Easy access to MCU input/output through Arduino R3TM compatible I/O connectors

• Programmable OpenSDAv2 debug circuit supporting the CMSIS-DAP Interface software that

provides:

o Mass storage device (MSD) flash programming interface
o CMSIS-DAP debug interface over a driver-less USB HID connection providing run-

control debugging and compatibility with IDE tools

o Virtual serial port interface
o Open-source CMSIS-DAP software project: github.com/mbedmicro/CMSIS-DAP.

• Ethernet

• SDHC

• Add-on RF module: nRF24L01+ Nordic 2.4GHz Radio

• Add-on Bluetooth module: JY-MCU BT board V1.05 BT

Figure 1 shows the block diagram of the FRDM-K64F design. The primary components and their

placement on the hardware assembly are explained in Figure 2.
