Board Overview
1.1 MC9S08MP16 Controller Daughter Board for BLDC/PMSM Motor Control
Drive Outline
Freescale’s MC9S08MP16 Controller Daughter Board for BLDC/PMSM Motor Control Drive together
with a 3-Phase BLDC/PMSM Motor Control Drive board create a single unit for developing
BLDC/PMSM motor-control applications.
The daughter board is connected via two connectors to the 3-Phase BLDC/PMSM Motor Control Drive
board. All necessary signals are available to allow a variety of algorithms to control the 3-Phase PMSM
and BLDC motors.
Figure 1-1 is an illustration of the controller daughter board.

Setup Guide
1.3 Setup Guide
Setup and connections for the MC9S08MP16 Controller Daughter Board for BLDC/PMSM Motor
Control Drive are straightforward. The controller daughter board plugs into the main board via two 20-pin
daughter board connectors. The system can be powered by a 12 to 24 V DC power supply. For safety
reasons, and ease of making measurements, use a regulated DC supply. Limit power supply to under five
amps.
Place jumpers to route the required signals to the controller. For jumper settings, visit chapter 2.2.4 ADC
Configuration Header JP1.
A step-by-step setup procedure for the main board is available in the 3-Phase BLDC/PMSM Motor Control
Drive Users Manual LVMCDBLDCPMSMUG.
WARNING
Check the power supply voltage before plugging in the Controller
Daughter Board. If an input voltage higher than 24 V is applied, the
controller daughter board can be damaged.
1.4 Board Description
The Controller Daughter Board is populated with an MC9S08MP16 8-bit HCS08 controller. All the
necessary signals are available on two 20-pin Rib-cage connectors, J1 and J2. BDM header J3 is used for
program upload onto the controller. Headers J4 and JP1 are configuration headers and are used for board
configuration. For more details, look into 2.2.3 Configuration Header J4 and 2.2.4 ADC Configuration
Header JP1.
Board schematic is available in Appendix A. MC9S08MP16 Controller Daughter Board for BLDC/PMSM
Motor Control Drive Schematics.

Pin Description
2.1 Introduction
Inputs and outputs are located on seven connectors and headers available on the board:
• Two 20-pin daughter board connectors J1, J2
• BDM header J3
• Configuration header J4
• ADC configuration header JP1
Pin descriptions for each connector and header are identified in the following information.
Figure 2-1 shows the pin assignments for the daughter board connectors J1 and J2.
Table 2-1 and Table 2-2 show the signal descriptions. JP1 configuration header is used to share AD
converter inputs for BEMF voltages and phase currents.
2.2 Signal Descriptions
Pin descriptions are identified in this subsection.
2.2.1 Daughter Board Connectors J1 and J2
Signal inputs and outputs for interconnection with the 3-Phase BLDC/PMSM LV Motor Control Drive are
situated on two 20-pin connectors, located on the board’s bottom-side. Figure 2-1 shows the pin
assignments. This figure shows the physical layout of the connectors, assuming that the board is oriented
upside down (bottom is up).
Table 2-1 and Table 2-2 contain the lists of signal descriptions for connectors
J1 and J2.
