DC bus voltage input: There
are three DC bus voltage input interfaces. Each interface receives
the DC bus voltage from a driver board. The voltage is then sampled
and transmitted to the ADC pins of the MCU for motor control
applications. Moreover, the voltage from the mandatory driver board
is exploited by the DC/DC converter as the input to generate DC 12V,
5V, and 3.3V voltage sources.
Phase current sample inputs:
There are three phase current sample input interfaces. Each
interface receives two phase current samples from a driver board.
The samples are then regulated and optionally transmitted to the ADC
pins of the MCU for motor control applications.
DC bus current sample input:
There are three DC bus current sample input interfaces. Each
interface receives the lower-side DC bus current sample from a
driver board. The sample is then regulated and optionally
transmitted to the ADC pins of the MCU for motor control
applications. The above-mentioned phase current samples share the
same ADC pins with the DC bus current sample. The user can select
one and only one kind of sample for the ADC either the phase current
or the DC bus current.
HALL signal inputs and Quadrature
encoding (QE) signal inputs: There are three HALL signal
input interfaces and three QE signal input interfaces. The HALL
signal input interfaces are independent from the QE signal input
interfaces. The HALL signals are then transmitted to the GPIO pins
of the MCU. These GPIO pins can work as the pins for the Input
Capture peripherals. The QE signals are then transmitted to the QEI
peripherals of the MCU. Both types of signals are useful for
sensored motor control applications.
PWM output: There are three
PWM output interfaces. Each interface transmits six PWM signals for
one driver board.
DC 12V output: There are three
DC 12V output interfaces. Each interface provides a DC 12V voltage
source to one driver board as the power supply for the driver
circuit.
UART: There are two UART
interfaces: one is dedicated and the other shares pins with the CAN
interface.
CAN: There is one CAN
interface, which shares pins with one UART interface.
SPI: There is one SPI
interface.
ICSP: There is one ICSP
interface to program or debug the MCU. The interface supports an
in-circuit debugger, such as ICD-4 or PICkit-4.
5V/3.3V/12V outputs: There are
three 5V output interfaces, three 3.3V output interfaces, and three
12V output interfaces.
