2 Pin Configuration

The following tables show the pin configurations for each individual device from the IMC300 series in the available packages. The pin type is specified as follows:  P – power and ground pins  I - digital input  O - digital output  IO – digital input or output  AIN - analog input  AO – analog output Each of the IMC300 cores has control over a different set of pins. The MCE core pins are labeled by system function which can be a single fixed function or multiple function options that are selected according to the MCE software configuration. The MCE functions and configuration options are described in the MCE software reference manual. The user application core (MCU) pins are labeled by port number (Pn.m) and have peripheral I/O functions selected according to the user software. The peripheral I/O function selection and configuration options are described in the IMC30xA hardware reference manual. Pins that do not have any signal assigned are reserved for future use. These pins should be left unconnected and neither be connected to ground nor to the positive supply. Note: The reference voltage for motor current trip protection is generated by an internal DAC, therefore pins like REFU, REFV, and REFW only require a blocking capacitor.

3 Functional Description

The IMC300 architecture is based on the combination of the Motion Control Engine (MCE) for Hall sensor based or sensorless motor control and PFC regulation and an additional microcontroller (MCU) based on an Arm® Cortex®-M0 core. The MCE contains an embedded motor control algorithm with fast angle sensing at startup and enables low and ultra-high speed operation, and offers either single shunt current sensing or leg shunt current sensing. PFC control supports two topologies, namely a single stage boost mode PFC and a totem-pole PFC with 50 kHz fast switching application to minimize the inductor size. Users can configure the motor and PFC parameters for each specific motors and store into the onboard Flash memory. The MCE also contains the UL 607310-1 software safety certified library and modules. The MCU is based on an Arm® Cortex®-M0 core and provides 128 Kbyte of flash and 16 Kbyte of RAM memory. The peripheral set is targeting communicaton and system application tasks. Both units – MCE and MCU – run largely independantly up to the fact that the MCU can be debuged while the motor is still running. Communication between the two units is using a fast serial interface called JCOM. Figure 6 shows the application schematics diagram for a single motor control system with single shunt current sensing configuration.

4 Electrical characteristics and parameters

4.1.1 Parameter Interpretation

The parameters listed in this section represent partly the characteristics of the IMC300 and partly its requirements on the system. To aid interpreting the parameters easily when evaluating them for a design, they are indicated by the abbreviations in the “Symbol” column:

  • CC Such parameters indicate Controller Characteristics, which are distinctive feature of the IMC300 and must be regarded for a system design.
  • SR Such parameters indicate System Requirements, which must be provided by the application system in which the IMC300 is designed in.

4.1.2 Absolute Maximum Ratings

Stresses above the values listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions may affect device reliability. Table 2 Absolute Maximum Rating Parameters Parameter Symbol Values Unit Note or Test Condition Min. Typ. Max.

4.1.3 Pin Reliability in Overload

When receiving signals from higher voltage devices, low-voltage devices experience overload currents and voltages that go beyond their own IO power supplies specification. Table 3 defines overload conditions that will not cause any negative reliability impact if all the following conditions are met:

  • full operation life-time is not exceeded
  • Operating Conditions are met for - pad supply levels (VDDP) - temperature If a pin current is outside of the Operating Conditions but within the overload conditions, then the parameters of this pin as stated in the Operating Conditions can no longer be guaranteed. Operation is still possible in most cases but with relaxed parameters. Note: An overload condition on one or more pins does not require a reset. Note: A series resistor at the pin to limit the current to the maximum permitted overload current is sufficient to handle failure situations like short to battery.

4.2.2 Power-Up and Supply Threshold Characteristics

This chapter provides the characteristics of the supply threshold in IMC300. The guard band between the lowest valid operating voltage and the brownout reset threshold provides a margin for noise immunity and hysteresis. The electrical parameters may be violated while VDDP is outside its operating range. The brownout detection triggers a reset within the defined range. The prewarning detection can be used to trigger an early warning and issue corrective and/or fail-safe actions in case of a critical supply voltage drop.

Device and Package Specification Thermal Characteristics Table 28 Package Thermal Characteristics Note: For electrical reasons, it is required to connect the exposed pad to the board ground VSSP, independent of EMC and thermal requirements. When operating the IMC300 in a system, the total heat generated in the chip must be dissipated to the ambient environment to prevent overheating and the resulting thermal damage. The maximum heat that can be dissipated depends on the package and its integration into the target board. The “Thermal resistance RΘJA” quantifies these parameters. The power dissipation must be limited so that the average junction temperature does not exceed 115° C. The difference between junction temperature and ambient temperature is determined by ΔT = (PINT + PIOSTAT + PIODYN) × RΘJA The internal power consumption is defined as PINT = VDD × IDDP (switching current and leakage current). The static external power consumption caused by the output drivers is defined as PIOSTAT = Σ((VDD - VOH) × IOH) + Σ(VOL × IOL) The dynamic external power consumption caused by the output drivers (PIODYN) depends on the capacitive load connected to the respective pins and their switching frequencies. If the total power dissipation for a given system configuration exceeds the defined limit, countermeasures must be taken to ensure proper system operation:  Reduce VDD, if possible in the system  Reduce the system frequency  Reduce the number of output pins  Reduce the load on active output drivers
