Introduction

Chapter 1 Introduction

This user manual introduces the S12ZVML-MINIBRD board, which represents the MC9S12ZVML128

small footprint board design.

The MC9S12ZVML128 [3.] integrates a 16-bit microcontroller, an automotive voltage regulator, a LIN

interface and a gate driver unit, in order to drive six external MOSFETs.

The S12ZVML-MINIBRD board is designed for a 3-phase BLDC and PMSM sensorless motor control

application. The board can be used for other applications requiring load switching and load current

monitoring as well. An application can be controlled using LIN and FreeMASTER [4.].

For more information on BLDC sensorless applications, see AN4704 [7.].



Introduction

1.1 Board Features

The board was designed to demonstrate the minimal hardware configuration needed for a 3-phase BLDC

and PMSM sensorless motor control application to achieve minimum board size. The board features are

as follows, see Figure 1-1 and Figure 1-2:

• MC9S12ZVML128 MCU

• power supply voltage in the range of -25 V to +25 V, nominal +12 V

• reverse battery protection

• load current in range of -10 A to +10 A

• load current monitoring

• boost circuitry designed to allow driving Vgs = 10 V MOSFETs from a +3.5 V power supply

• on-board charge pumps to allow driving the high side MOSFETs

• analog and digital inputs for target application control and monitoring

• FreeMASTER enabled

• LIN enabled

• BDM enabled

• OSBDM enabled:

— download and debug MCU code

— virtual serial line (USB to SCI)

• board size of 5 cm x 9 cm:

— MC9S12ZVML128 related part size of 5 cm x 5 cm

— OSBDM related part size of 5 cm x 4 cm

The on-board OSBDM module allows the user to download and debug code using the CW10.5 tool [5.]

without the need of a P&E Micro USB Multilink.

The FreeMASTER tool allows the user to control the on-board application via the PC USB line.

Introduction



Board Interface Description

Chapter 2 Board Interface Description

This chapter summarizes the on-board connectors and header pin-outs, signal meanings, and MCU pins

assignments.

2.1 J1 LIN Connector

The board is supplied using the LIN connector J1, see Table 2-1 for the connector pin-outs. The MCU is

configured as a LIN Slave node.

The J1 LIN connector opposite uses MOLEX 39-01-2040 with pins MOLEX 39-00-0039.

2.2 J9 USB Connector

The USB line is used for on-board OSBDM module communication with the PC. The OSBDM module is

used for MCU code download and debug using the CW 10.5 tool, as well as a virtual serial port when using

the FreeMASTER tool to control the user application.

The interface uses a USB 2.0 B type connector, see Table 2-2.

port availability depends on the J6 and J8 configuration, see Table 1-1.

2.6 JP1, JP2, JP3 Motor Terminal Pins

Design Consideration

Chapter 3 Design Consideration

The S12ZVML-MINIBRD board schematic can be found in Chapter 8, “S12ZVML-MINIBRD

Schematic".

3.1 Power Supply

The board is supplied using the J1 LIN connector, see Table 1-1 for the connector pin-outs. The board

nominal power supply voltage equals +12 V. The board sustains negative voltages up to -25 V due to M1

reverse battery protection.

The power supply line is decoupled by C5. The value of the capacitor is dependent on the required power

supply voltage ripple, when board load, for example BLDC / PMSM motor, is PWM driven. The goal is

to achieve minimum power supply voltage ripple to reduce board electromagnetic emissions.

An on-board boost circuit, L1, D1, C1, C2 allows controlling the Vgs = 10 V MOSFETs starting from a

+3.5V power supply voltage. The boost circuitry is turned ON and controlled by the MCU GDU boost

controller module when the power supply voltage drops below +10 V. The boost circuitry is optimized for

operation at 520 kHz with the MCU GDU boost controller duty cycle set to 75% and the L1 inductor

current limit at 750 mA. The boost snubber circuitry R3 and C6 is included to dump the oscillations

appearing when the boost transistor is switched.

The on-board D7 +2.47 V voltage reference sets the ADC voltage, when the load current equals 0 A, see

Table 3-1.

3.2 MCU Related Circuity

The MCU is supplied with VSUP pin. The MCU on-chip +5 V voltage regulator generates the voltage for

the MCU digital and analog circuitry. The decoupling capacitors C7, C8, C9 reduce noise on the power

supply lines. The MCU analog power supply line noise is reduced using the ferrite bead L2 and capacitor

C12.

The GDU drives the Q1, Q2, Q3, Q4, Q5, Q6 MOSFETs configured in a 3-phase bridge unit with phase

outputs JP1, JP2, JP3. The GDU is supplied by the on-chip +11 V VLS regulator decoupled by C13, C14,

C18 and C19. Whenever the power supply voltage drops below +10 V, the boost circuitry starts to operate

and the VSUP voltage is maintained at +10 V. The boost circuitry allows driving the Vgs = 10 V MOSFETs

starting from a +3.5 V power supply voltage.

The J2 digital PT1 pin signal and J4 analog PAD3 signal can be used for an application monitoring and

control.

The PP0 pin controls the D8 LED. The PP0 shares the MCU clock output ECLK as well.

The J7 allows to connect board external device using the MCU SCI module. The availability depends on

J6 and J8 jumper header settings, see Table 1-1.

3.3 Charge Pumps

There are four charge pumps to supply the GDU HSDs modules.



Design Consideration

The D4, C15, D5, C16, D6, C17 charge pumps are driven by the phase voltages. They supply the GDU

HSDs when the PWM duty cycle is within minimal and maximal limits.

The D2, D3, C3, C4 charge pump is driven by the MCU VCP pin. This is used to supply the GDU HSDs

when the PWM duty cycle is either 0% or 100%.

3.4 Load Current Sense

The load current sense circuitry is designed to measure load current in both directions. This is useful when

the attached motor is controlled in dynamo mode as well.

The load current is sensed by R20 and amplified by the on-chip amplifier AMP0. The R19, R22, and C20

reduce the sense line noise. The R28 and C23 shape the AMP0 signal.

The load current conversion slope theoretically equals 0.125 V/ 1 A, see Table 3-1.

Table 3-1. Load current sense

3.5 BDM Interface

The on-board J3 BDM connector allows a download and debug of the code in the MCU using CodeWarrior

10.5 and P&E Micro USB Multilink.

The BDM interface can be used for application control using FreeMASTER as well.

3.6 OSBDM Interface

The on-board OSBDM interface allows a download and debug of the code in the MCU without any

additional debugging hardware. The P&E Micro USB Multilink is not needed.

The OSBDM interface can be used as a board virtual serial port for FreeMASTER based application

control.
