Table 3-13 lists the peripherals and pins of F28002x or F28003x used by this reference design. It is not allowed to use these peripherals for any other purposes, but the user can modify the pins assignment according to their hardware design.
Module | Purpose | Notes |
---|---|---|
EPWM1, EPWM3, EPWM5 | Motor 1 3-phase PWM | Total 6 PWM channels |
EPWM2, EPWM4, EPWM6 | Motor 2 3-phase PWM | Total 6 PWM channels |
EPWM7 | PFC 2-phase PWM | Total 2PWM channels |
ADCA, ADCC | Motor 1 and 2 currents | 3 ADC channels for current sensing each motor |
ADCA, ADCC | Motor 1 and 2 voltages | Only need for InstaSPIN-FOC, 3 ADC channels for voltage sensing each motor |
ADCA (F28002x, F280013x), ADCB(F28003x) | PFC current, AC input voltage and DC output voltage | |
CMPSS1, CMPSS3, CMPSS4 | Motor 1 and 2 3-phase overcurrent fault | Three-phase current over current fault protection each motor |
CMPSS2 | PFC overcurrent and DC bus overvoltage faults | |
X-Bar | CPIO and output of CMPSS to PWM trip | |
SCIA | Communication with indoor control | The other UART or LIN interface can be assigned for this also. |
CPU Timer 0 | Virtual timer for motor and system control in background loop | CPU timer 1 or 2 can be assigned for this also. |
