With its fast interrupt response and context switching, the C166 family is ideally suited for automotive, industrial, mass storage and wired as well as wireless communications applications. Compared with the XC166, XE166 delivers more performance, more Flash memory, more RAM, strongly enhanced peripherals and a complete DSP library. MCU and DSP in a core Infineon Technologies Real Time Signal Controller combines the traditional strengths of a Microcontroller Unit (MCU) to control peripherals with the computing power of Digital Signal Processors (DSP). All in one enhanced XE166 core. Together, the Microcontroller's real-time capability and ease of use and the DSP's mathematical performance and data throughput form a powerful singe-chip solution ideal for many embedded applications. For detailed technical information about the different derivatives please refer to the XE166 family web pages on the Infineon Internet. http://www.infineon.com/XE166 Application Note 5 V1.0, 2009-03 AP16160 XE164 DriveCard Hardware Description Board REV.2008/14 2 Overview The XE164 DriveCard was designed to be used in motor control systems. It provides all signals necessary to drive a power inverter including feedback signals.

These configurations are accomplished by latching the logic levels at a number of pins at the end of the internal reset sequence. Jumper 8 is used to configure the startup setting of the XE166 during RESET. The default System Startup Configuration is shown in Table 1 below. All Jumper positions are OFF. The XE166 executes a standard start from internal Flash. Table 1 Name in schematic Startup configuration Default configuration Description Startup configuration: Standard start from internal Flash (Default) JP8 1 2 3 Startup configuration: Standard UART Bootloader mode JP8 1 2 Note: For details about the UART Bootloader refer to the User Manual System Units. 3 Startup configuration: CAN Bootloader mode JP8 1 2 Note: For details about the CAN Bootloader refer to the User Manual System Units. 3 Note: For debugging purposes (OCDS) the standard start from internal Flash configuration must be used. Application Note 7 V1.0, 2009-03 AP16160 XE164 DriveCard Hardware Description Board REV.2008/14 3 Hardware Description 3.1 Power Supply The XE164 DriveCard is supplied by two power supply domains. The main supply (VCC) is fed from the inverter board connector (see Chapter 3.5) and is connected to the MCU and all associated blocks. A second supply domain (VCCIO) exists for the digital isolation and the CAN transceiver. This can be provided via the CAN or the JTAG connector. Please refer to Chapter 3.4 for details. Two LEDs indicate the presence of these supply voltages. 3.2 XE164 The XE164 microcontroller is directly connected to dedicated interfaces. Next to the integrated current trimmed oscillator, an external resonator with 8 Mhz is available. A software download can be performed via JTAG, UART or CAN. For a UART or CAN download, the dedicated BSL (Boot Strap Loader) has to be set (see Chapter 2.1). For normal operation, the Jumper must be 'off'. A reset button is available to trigger a hardware reset. Figure 2 XE164 Application Note 8 V1.0, 2009-03 AP16160 XE164 DriveCard Hardware Description Board REV.2008/14 3.3 User Interface There is a user interface available through a poti and a GPIO LED. The poti is connected to ADC0 channel 13, the LED is connected to port 0.2. A test pad is connected to this port as well in order to measure fast signals at an oscilloscope. Figure 3 User Interface: POTi and LED 3.4 Digitally Isolated Debug Interface (JTAG, UART and CAN) The XE164 DriveCard is equipped with a digital isolation for JTAG, UART and the CAN interface. The 5 kV digital isolation securely disconnects any debug, UART and CAN devices from the high voltage levels. As there is a separate power domain for the PC part of the XE164 DriveCard, a 5 V power supply must be provided separately at VCCIO and GNDIO. LED1 indicates the availability of this supply domain. There is a DriveMonitor USB Stick available from Infineon Technologies that provides JTAG and CAN as well as the 5 V power supply in one device. Please refer to application note AP08071 for details. Figure 4 JTAG, UART and CAN: Debugger and Real Time Monitoring Interface Note: When a standard JTAG box is used, the VCCIO power supply must be provided at the CAN connector. Application Note 9 V1.0, 2009-03 AP16160 XE164 DriveCard Hardware Description Board REV.2008/14 3.5 Inverter Board Connection The standard 32-pin connector (DIN 41612, B/2) provides all signals needed for control of two 3-phase power inverter. The lowside (_L) and highside (_H) switches of the three power stages U, V and W are to be connected to the signals U_L, U_H, V_L, V_H, W_L and W_H. They are connected to the MCU’s CAPCOM6E peripherals CCU60 and CCU62, flexible and powerful PWM units very well suited for motor control. A low signal at the CTRAP pins of the CAPCOM6E immediately switches all power stages in passive state and acts as an emergency shutdown for the inverter. All CAPCOM6E signals, including COUT63, are available at pin header JP1 for CCU60 and JP5 for CCU62. An enable signal for the power stages can be provided via signal ENABLE Signals which are connected to the MCU’s GPIO port 0.0 and 0.1. Figure 5 Power Board Connector A 5 V power supply is expected at pins A1 and B1 of the inverter board connector in order to supply the MCU and peripheral components. Application Note 10 V1.0, 2009-03 AP16160 XE164 DriveCard Hardware Description Board REV.2008/14 3.6 Hall Sensor Interfaces The MCU provides two HALL sensor interfaces which can be accessed via JP2 and JP6. Next to the HALL signals that are pulled up to VCC = 5 V, the VCC and GND signals are available as well. Figure 6 Hall Sensor Interfaces 3.7 USIC Interface The USIC1 Channel1 signals from the MCU are provided at JP3. This interface is connected directly to the MCU , and is therefore not isolated form the hot ground of the power inverter. The Interface can be used as ASC or SSC. The signals of JP3 can be mapped to GPIOs of the XE164 as well. Figure 7 USIC Interface (SSC, ASC) Application Note 11 V1.0, 2009-03 AP16160 XE164 DriveCard Hardware Description Board REV.2008/14 3.8 Encoder Interface The Encodeer Signals ENC_A and ENC_B are conected to the Timer 2 input. T2 operates in incremental interface mode automatically providing information on the sensor’s current position. In incremental interface mode, the two inputs associated with core timer T2 (T2IN, T2EUD) are used to interface to an incremental encoder. T2 is clocked by each transition on one or both of the external input pins to provide 2fold or 4-fold resolution of the encoder input. The Encoder_Top signal is connected to pin 2.2. With the ERU unit this pin can act like an external Interrupt request pin.
