Hardware​

Hardware functional description

This section provides a detailed explanation of the individual hardware blocks used in this kit.

PSOC™ Control C3M5 motor control card

The control card is designed for the PSOC™ Control C3M5 microcontroller in an E-LQFP-80 package. The onboard isolated J-Link debugger is implemented using the XMC4200 microcontroller. All the I/Os from the PSOC™ Control C3M5 MCU are routed out to the 100-pin high-density (HD) connector, which can be inserted into a mating connector on the included adapter board. The adapter board, in turn, provides connectivity to the motor control power boards using MADK M1/M3, M5, and Samtec connectors.

PSOC™ Control C3M5 MCU

Figure 12.

PSOC™ Control C3M5 MCU block diagram



The PSC3M5xD devices are based on the Arm® Cortex®-M33 microcontroller, running at up to 180 MHz with DSP and FPU capabilities. In addition to the CPU subsystem, the devices contain advanced real-time control peripherals, such as a high-performance programmable analog subsystem, comparators, advanced timers with high-resolution capability, up to six serial communication blocks (SCBs), and two CAN FDs for communication. The devices support one Active mode and five low-power modes for managing and reducing power consumption depending on application requirements.

Figure 13.

PSOC™ Control C3 MCU pin connections



PSOC™ Control C3M5 MCU power supply system

The PSOC™ C3M5 MCU operates using a single regulated VDDD supply within the range of 1.71 V to 3.6 V. Additionally, there is an optional VBACKUP supply, which has a range of 1.4 V to 3.6 V. A linear regulator powers the core logic at four voltage levels: 0.9 V, 1.0 V, 1.1 V, and 1.2 V. Voltage level switching is implemented by writing to the power control registers. The voltage for the core logic can be set based on the application's performance and power requirements.

Typically, the backup domain requires an input voltage of 1.4 V to 3.6 V, which can be provided by connecting a backup battery or a supercapacitor to the VBACKUP pin. The internal backup switch automatically selects between VDDD and VBACKUP (when VDDD is no longer available) for powering the backup domain peripherals like the RTC, WCO, ILO, and backup registers. Some I/O cells are powered from the VBACKUP supply before the internal backup switch. If the application does not require a dedicated backup source, VBACKUP can be connected to VDDD externally to ensure that the I/O cells powered by VBACKUP are functional.

Figure 14.

PSOC™ Control C3 MCU power supply scheme



The PSOC™ Control C3 MCU operates at 3.3 V, while the rest of the board requires both 3.3 V and 5 V supplies. The VDD3.3, used to power the MCU, is generated using the U2 low-dropout regulator. The VDD5 rail, which powers this regulator as well as the rest of the circuits running on 3 V or 5 V, can be sourced from any of the following options:

  1. Isolated USB supply

    : The USB 5 V supply is used to power a 5 V to 7 V DC-DC isolated converter, which in turn generates a 5 V supply, VDCDC5, using U14. This supply can be used to power the board when the X20 jumper is set to the 1-2 position

  2. 5 V or 24 V supply from the power board

    : When the X20 jumper is set to the 2-3 position, the board can be powered by any of the following sources:

    1. High-density HD connector (X15)

      : Either a 24 V supply on pin B41, converted to 5 V using U16, or a 5 V supply on pins B5/B10 of the 100-pin high-density connector

    2. MADK5 power board header (X19)

      : A 5 V supply on pin 2 of the X19 header can be used to power the board

Multiple 5 V sources, which come from the power stage (either direct 5 V or 24 V regulated to 5 V), are ORed using low-drop rectifiers based on the Q3, Q4, and Q6 MOSFETs.

MADK M5 header (X19)

: The MADK M5 header provides the same pinout available in the MADK M5 connector on the drive adapter card, using a 16x2 male header with a standard 2.54 mm pitch. This header can be used for hardware debugging or probing signals.

ADC input buffers

Figure 17.

ADC signal input buffers and scaling circuit



The analog signals coming from power stages, such as phase currents or back electromotive force (BEMF) voltages, DC link current, bus voltage, etc., are buffered using a unity gain amplifier followed by a potential divider to make 5 V analog signals compatible with the 3.3 V analog-to-digital converter (ADC) in the PSOC™ Control C3 MCU. When using a power stage with 3.3 V compatible analog signals, the divider network can be disabled by removing the 1.96 kΩ low-side resistors: R105, R117, R118, P119, R123, R124, R125, R136, R137, R138, R139, R147, and R149.

Digital isolators and CAN interface

Figure 20.

Digital isolators and CAN interface



Isolation for the SWD and UART lines is achieved using a digital isolator (U10). The CAN signal uses a dedicated isolator (U4), while the USB power supply is isolated from the target side using an isolated DC-DC converter (U20). An isolated CAN interface is available on the X14 header. Additionally, by mounting the X28 jumper, a 120 Ω termination resistor can be enabled on the CAN_P and CAN_N lines.

PSOC™ Control C3M5 MCU clock architecture

Figure 21.

PSOC™ Control C3 MCU clock architecture



Figure 21

shows the MCU clocking scheme. A 16 MHz ECO is used as a source for the FLL, while a 48 MHz IHO is used as a source for DPLL0 and DPLL1. The FLL is configured to 100 MHz and supplies the clock to CLK_HF2 (CAN, SCB). DPLL0 is configured to 180 MHz and supplies the clock to CLK_HF0 (CPU, Crypto) and CLK_HF1 (IOSS, SMARTIO, LPCOMP). DPLL1 is configured to 240 MHz and supplies the clock to CLK_HF3 (TCPWM, MCPASS) and CLK_HF4 (SCB5). Other clocks are optional.

PSOC™ Control C3M5 MCU external programming or debugging headers

Figure 22.

External debugger connections



The board features a 10-pin Cortex® header (X12) and a 20-pin ETM header (X1). It also includes a proprietary 12-pin header (X11) with SWD, UART, and SPI interfaces. All the headers have a 1.27 mm pitch.

The selection between the onboard debugger or the Cortex® 10-pin header (X12) and the proprietary 12-pin header (X11) is managed using the SW3 DIP switches.

Note:

The external debugger or serial interfaces are not isolated.

XMC4200 as an onboard programmer/debugger

Figure 23.

XMC4200-based J-Link lite programmer/debugger



The XMC4200 (U7)-based onboard J-Link Lite programmer/debugger provides the SWD interface as well as the UART interface over USB for the target MCU. XMC4200 is powered using the 5 V USB supply, which is converted to 3.3 V using the U8 voltage regulator. The debug LED (D5) is ON when the USB interface is connected to the PC. The aux LED (D4) blinks during active communication between the debugger and the target MCU.

Hall sensor and encoder interface

Figure 24.

Hall sensor and encoder interface



The Hall sensors (X3 and X7) and encoder interfaces (X2 and X4) allow users to connect motors with Hall sensors or incremental encoders for sensor-based motor control applications. The board supports both differential and single-ended ABZ encoders. When using single-ended encoders, the input signal is connected to the ENCx_A_P, ENCx_B_P, and ENCx_Z_P pins of the X2 and X4 connectors, while the corresponding N lines are connected to GND.

For motor 1, the selection between the Hall sensor or encoder is done using the M1_ENENC_M signal connected to P4.7 of the MCU. When this pin is set to logic low, the Hall 1 inputs (X3) are enabled. When set to logic high, the encoder 1 inputs (X2) are enabled. For motor 2, this selection is done using the jumper JP1. When JP1 is open, the Hall 2 inputs (X7) are enabled. When JP1 is closed, the encoder 2 inputs (X4) are enabled.
