VERVIEW
Active-Semi’s PAC5222EVK1 development platform is a complete hardware solution enabling users not only
to evaluate the PAC5222 device, but also develop power applications revolving around this powerful and
versatile ARM
®
Cortex
®
-M0 based microcontroller. The module contains a PAC5222 Power Application
Controller
®
(MCU) and all the necessary circuitry to properly energize the MCU and its internal peripherals
once power is applied.
To aid in the application development the PAC5222EVK1 offers access to each and every one of the
PAC5222 device’s signals by means of a series of male header connectors.
The PAC5222EVK1 also contains access to an external USB to UART module enabling users to connect the
evaluation module to a PC computer through a conventional Virtual Comm Port which can then be used in the
communication efforts by taking advantage of the PAC5222’s UART interface. Graphical User Interface (GUI)
software suites can be employed to externally control particular application’s features.
Finally, the PAC5222EVK1 module gives access to the PAC5222’s SWD port allowing users to both program
the application into the device’s FLASH memory, as well as debug the application in real time. The provided 4
pin connector is compatible with a decent variety of SWD based debugger/programmer modules, widely
available.
Active-Semi’s PAC5222EVK1 evaluation kit consists of the following:

Power Input
Power to the PAC5222EVK1 evaluation module can be applied to the VIN and GND spade connectors.
Power to the PAC5222EVK1 evaluation module should not exceed 40V (Abs Max).
The PAC5222EVK1 is optimized to operate with voltages ranging from 14V to 24V Nominal (40V Abs Max).
When the VIN input voltage goes above 8V, the system exits UVLO protection and all subsystems, including
voltage regulators, analog front end and microcontroller, are enabled.
LED’s
When an operational voltage is applied, LED D16 will light up. This is the LED which notifies VSYS (5V) rail is
up and running. VP (12V gate drive), 3.3V (for analog circuitry) and 1.2V (for CPU core) regulators will also be
operating at this point in time. Module is ready for use.
The following table shows the available LEDs and their associated diagnostic function.

Hall Sensor / DAC Interface
Terminal Block J10 offers access to the PAC5222 resources on PORTD utilized for hall sensor based
commutation. These resources can be alternatively utilized as PWM DAC outputs for in real time debugging.
Jumpers JMP1/2/3 are used to select the preferred function.
NOTE: 2 pin shunts must be placed on the JMP1/2/3 in order for the respective PORTC resources to be
made available.

ETUP
The setup for the PAC5222EVK1 evaluation module requires up to four simple connections.
1. Connect the VIN power source via spade tab connectors VIN and GND. As VIN power is applied, the
LED D7 will light up. Once VIN voltage goes above 8V, the PAC5222’s Multi Mode Power Manager
will be engaged and the VSYS (5V) regulator will be enabled. This event will result in LED D16
lighting up.
2. Connect the 3 Phase BLDC/PMSM motor via space tab connectors PHASE U, PHASE V and PHASE
W.
3. If Serial Communications are desired, connect the USB to UART module 4 pin connection to J7.
4. For debugging/programming, connect a suitable USB SWD module to J1 by using a standard 4 wire
cable.
