JTAG Interface

JTAG access to the CPLD of CR00140 is possible via the CRUVI high speed connector J9 and the pinheader J10, which is a base for TEI004 JTAG programmer. The JTAGEN signal is pulled up and available on J9 only. If JTAGEN is pulled low, the four signals can be used as user I/Os.

Sensor Interface

The pin headers J1, J2 and J3 constitute the sensor interface. It can be e.g. used with Encoders or Hall sensors. J3 is the selector between differential sensor interface (J2) or single ended sensors (J1). Connecting sensors is only allowed to one of the two pinheaders (J1/J2), the other one has to stay unconnected. In the figure below the jumper configuration of J3 to enable one or the other type of sensor interface is depicted.

CR00140 Jumpers

The pinheaders for connection of the sensors are further described in the following table. For differential configuration 100 Ohm parallel termination is used.

On-board LEDs


There are three isolating AD7403-8 ADCs for continous measurement oft phase A current (U3), phase B current (U5) and the DC_LINK voltage (U7) on board. The currents are measured through the shunt resistors R22, R28 for phase A and B respectively. The ADC clock is routed to the CPLD. For Currents the clock has the signal lable SCLK_A and for the voltage SCLK_V_A. The data signals are also routed to the CPLD. See CPLD Firmware for further description.


Back EMF zero crossing signals for sensor-less motor control are implemented for Phase A, B and C. They are routed via a triple channel Digital isolator (U15) to the CPLD. See CPLD Firmware for further description.

Half bridge drivers

Four ADuM7223 isolated half bridge drivers (U8, U9, U10, U11) are used for driving the four phases.


On the Motor side are two DCDCs on board. LTM8053 (U1) is utilized for the generation of the 15V transistor control voltage from VIN and can be measured on Testpoint TP1. A LTM8074 DCDC (U2) generates 5V from VIN for miscellaneous signals on the motor side of the PCB and can be measured on TP2.

Two isolated DCDCs ADUM5028 (U4, U6) are used for the generation two seperate clean 5V for the supply of the current measurement ADCs U3 and U5.

Power and Power-On Sequence


The 2K Microchip 24AA02E48 EEPROM with pre-programmed unique 48bit address is connected to the CRUVI HS (Signals: SMB_SDA, SMB_SCL) connector and can e.g. be used for identifiction purposes.

Power Supply

The motor driving stage is supplied via connector J7 with maximum of 40V DC. Polarity of the powersupply is noted on the PCB.  

Check powersupply for correct polarity. Inversion of polarity will damage the module. At least Transistor T11 may be harmed. Furthermore make sure that under any circumstances the absolute maximum voltage does not exceed 42V.

Power Consumption

The power consumption on the motor stage side (J7) is dominated by the connected motor and the corresponding driving algorithm. The idle consumption is given below.
