FRDM-KE02Z40M User’s Guide

1 Overview

The Freescale Freedom Development Platform

is an evaluation and development tool ideal for

rapid prototyping of microcontroller-based

applications. The hardware design is form-factor

compatible with popular third-party hardware

designed to work with Arduino™ and Arduino-

compatible boards.

The Freescale KE02Z Freedom Board (FRDM-

KE02Z40M) is a simple, yet sophisticated

design featuring the Kinetis E Series

microcontroller KE02Z64VQH4, the industry’s

first 5 V microcontroller built on the ARM

Cortex

-M0+ core.

The Kinetis E series is the most scalable

portfolio of low-power, high-robustness, mixed

signal 32-bit ARM Cortex-M0+ MCUs running

up to 48 MHz in the industry. It supports power

supply voltage range from 2.7–5.5 V, ambient

operating temperature range from –40 °C to

105 °C and includes up to 64 KB flash memory.

Main supply rail for the board Can be sourced from P3V3_VREG, or directly from the I/O headers (J9 pin 8), or from P3V3_MOTOR. KE02Z MCU power supply Header J3 provides a convenient means for KE02Z energy consumption measurements. P3V3_SDA OpenSDA circuit power supply Header J4 provides a convenient means for K20 energy consumption measurements.

to-USB converter run in parallel to provide a virtual COM communication interface while allowing code debugging via OpenSDA with just single USB connection. These two applications are provided in a single code package. See to the OpenSDA User’s Guide, available on freescale.com, for more details. Figure 3. OpenSDA block diagram OpenSDA is managed by a Kinetis K20 MCU built on the ARM Cortex-M4 core. The OpenSDA circuit includes a status LED (D4) and a RESET pushbutton (SW1).

4.10 Input/Output headers The KE02Z64 microcontroller is packaged in a 64-pin QFP package. Some pins are utilized in onboard circuitry, but many are directly connected to one of four I/O headers (J1, J2, J9 and J10). Headers J1 and J2 also function as motor control headers to provide access to a motor control board such as simple BLDC motor driving board APMOTOR56F8000E. Figure 10. I/O headers 4.
