FRDM-KE06 hardware description Figure 1. FRDM-KE06 block diagram The FRDM-KE06 features two microcontrollers, the target MCU and a serial and debug adapter (OpenSDA) MCU. The target MCU is a Kinetis E series KE06 family device. The OpenSDA MCU is a Kinetis K series K20 family device, the K20DX128VFM5. 2 2.1 FRDM-KE06 hardware description Power supply The FRDM-KE06 offers a design with multiple power supply options. It can be powered from the USB connector, the VIN pin on the I/O header, an off-board 1.

Serial and Debug Adapter (OpenSDA) 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). The pushbutton asserts the reset signal to the KE06 target MCU. It can also be used to place the OpenSDA circuit into Bootloader mode by holding down the reset pushbutton while plugging the USB cable to USB connector J6.

Serial and Debug Adapter (OpenSDA) Figure 4. SWD debug connector to KE06 3.2 Virtual serial port A serial port connection is available between the OpenSDA MCU and UART1 pin PTC7 (TXD1) and PTC6 (RXD1) of KE06. Several of the default OpenSDA applications provided by Freescale, including the MSD Flash Programmer and the P&E Debug Application, provide a USB Communications Device Class (CDC) interface that bridges serial communications between the USB host and this serial interface on the KE06. 3.3 3.3.

Serial and Debug Adapter (OpenSDA) 3.3.4 Debug The sole debug interface on all Kinetis E Series devices is a Serial Wire Debug (SWD) port. The primary controller of this interface on the FRDM-KE06 is the onboard OpenSDA circuit. However, a 2x5-pin (0.05”) Cortex Debug connector, J7, provides access to the SWD signals for the KE06 MCU. The following table shows SWD connector signals description for KE06: Table 3. ARM JTAG/SWD mini connector description Pin 3.4 Function Connection to KE06 1 VTref 3.

Serial and Debug Adapter (OpenSDA) Figure 10. CAN 3.10 Input/Output headers The KE06 microcontroller is packaged in an 80-pin LQFP. Some pins are utilized in on-board circuitry, but many are directly connected to one of four I/O headers (J1, J2, J3, J4 and J5). 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.

I/O headers 3.11 Arduino compatibility The I/O headers on the FRDM-KE06 are arranged to allow compatibility with peripheral boards (known as shields) that connect to Arduino and Arduino-compatible microcontroller boards. The pins on the headers share the same mechanical spacing and placement as the I/O headers on the Arduino Uno Revision 3 board design. See Figure 11 for compatible signals.
