Getting Familiar with the controlCARD
4 Getting Familiar with the controlCARD
4.1 F28P65X controlCARD Features
•
F28P65X Microcontroller – High performance C2000 microcontroller is located on the controlCARD.
•
180-pin HSEC8 Edge Card Interface – Allows for compatibility with all of C2000 180-pin controlCARD-
based application kits and controlCARDs. Compatibility with 100-pin controlCARDs can be accomplished
using the TMDSADAP180TO100 adapter card (sold separately).
•
Built-in Isolated JTAG Emulation – An XDS110 emulator provides a convenient interface to Code
Composer Studio
™
IDE without additional hardware. Flipping a switch allows an external JTAG emulator
to be used.
•
Built-in Isolated Power Supply - Passes the 5-V supply from the USB-C connector through an isolation
barrier. Allows for the controlCARD to be completed powered and operated from the USB-C connector. The
F28P65X is fully isolated from the USB port.
•
Automatic Power Supply Switch - The controlCARD automatically switches to external 5-V power when
present. No additional configuration is required.
•
Connectivity – The controlCARD contains connectors that allow the user to experiment with isolated
universal asynchronous receiver/transmitter (UART)/SCI with the F28P65x MCU.
•
Key Signal Breakout – Most GPIO, analog-to-digital converter (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 ADC input pins.
The controlCARD uses DP83826 10/100M Ethernet PHY for EtherCAT communication. This PHY has reduced
and more deterministic round trip (TX+RX) latency of < 210 ns ± 2 ns. In addition the XI to TX_CLK clock phase
delay is ± 2 ns. These features, along with robust EMI/EMC performance, make DP83826E/I an excellent choice
for real time applications. For more details, see

4.2 Assumed Operating Conditions
This kit is assumed to run at standard room conditions. Standard ambient temperature and pressure (SATP) with
moderate-to-low humidity is assumed.
4.2.1 External Power Supply or Accessory Requirements
Nominal Output Voltage: 5 VDC
Maximum Output Current: 3 A
Efficiency Level V
TI recommends using an external power supply or power accessory that complies with applicable
regional safety standards such as (by example) UL, CSA, VDE, CCC, PSE.
