•
Connectivity – The controlCARD contains connectors that allow the user to experiment with USB, a
microSD card, and isolated UART/SCI with the F2837x MCU. A hi-density connector is also provided
to experiment with external memory.
•
Key Signal Breakout – Most GPIO, ADC and other key signals routed to hard gold connector fingers.
•
Robust Power Supply Filtering – Single 5 V input supply powers an on-CARD 3.3 V LDO. All MCU
inputs are then decoupled using LC filters near the device.
•
ADC Clamping – ADC inputs are clamped by protection diodes.
•
Anti-Aliasing Filters – Noise filters (small RC filters) can be easily added on several ADC input pins.

Assumed Operating Conditions
This kit is assumed to run at standard room conditions. The EVM should run at approximately standard
ambient temperature and pressure (SATP) with moderate-to-low humidity.
3.3
Using the controlCARD
In order for the controlCARD to work, the controlCARD’s MCU must be powered. This is most often done
by inputting 5 V through the HSEC connector via an accompanying baseboard. For example, if using a
docking station baseboard, 5VDC should be input into the docking station’s J1 or J17. Then, SW1 needs
to be toggled to the appropriate position.
Optionally, the MCU could also be powered via the micro-USB connector on the controlCARD.
Based on the way the controlCARD will be used, additional hardware settings are necessary, see

For users new to C2000’s F28x7x series of devices and CCS, TI’s Technical Training Organization
provides several workshops (online and in person) that may be helpful:

The following PDF documents are provided to describe where each of the F2837x MCU’s pins will appear
on the controlCARD connector/docking station:
