Warnings, Notes, and Errata
Notes for all controlCARDs:
•
The F280049C Experimenter’s Kit ships with a USB cable and is designed to be powered through
USB. However, when external components are added to the docking station for experimentation, the
board or controlCARD may require more power than the 5 V @ 500 mA that a computer’s USB port
can provide. This is especially true when additional circuitry has been added to the docking station. In
such cases, TI recommends using an external 5-V power supply (2.5-mm inner diameter × 5.5-mm
outer diameter), and plug it into J1. A compatible supply could be the: Phihong PSAC05R-050(P)-R-C2
+ Phihong RPBAG
•
The MCU by default expects GPIO24 and GPIO32 to be the IO pins responsible for determining the
boot mode of the device at power up. These GPIOs may be edited by programming the OTP in the
device, if desired. Refer to the Boot ROM section of the specific device’s Technical Reference Manual
(TRM) for more information.

F280049C controlCARD Features
•
Piccolo F280049C Microcontroller
– High performance C2000 microcontroller is located on the
controlCARD.
•
120pin HSEC8 Edge Card Interface
– Allows for compatibility with all of C2000’s 120- or 180-pin
controlCARD-based application kits and controlCARDs. Compatibility with 100-pin DIMM
controlCARDs can be accomplished using the TMDSADAP180TO100 adapter card (sold separately).
•
Built-in Isolated JTAG Emulation
– An xds100v2 emulator provides a convenient interface to Code
Composer Studio without additional hardware. Flipping a switch allows an external JTAG emulator to
be used. This external emulator may use standard 4-pin JTAG or 2-pin cJTAG.
•
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.
3.4
Using the controlCARD
For the controlCARD to work, the controlCARD MCU must be powered. This is usually done by inputting 5
V through the HSEC connector through an accompanying baseboard. For example, if using a docking
station baseboard, 5 VDC should be input into the docking station’s J1 or J17, then SW1 must be toggled
to the appropriate position.
