2.2 Warnings About Specific controlCARD Revisions

Warnings about R1.0a revision F28377D controlCARDs:

  • Among many other changes made, the pinout of the R1.1 F28377D controlCARD is different from the pinout of the pre-release R1.0a controlCARDs. When porting code, see the kit documentation and schematics in the C2000Ware install on your computer in the /boards/controlCARDs subdirectory.

Warnings about R1.1 and earlier F28377D controlCARDs:

  • The F28377D MCU is not 5 V tolerant. Because of this, some additional protection is needed between the USB port J8 and the MCU. In particular, resistor R72 should change from 0R0 to 100K and resistor R74 should change from 0R0 to 10K. This effectively limits the voltage/current received by the MCU pin. This issue was fixed in R1.1a and later revision controlCARDs.
  • If used, the crystal X1 should be acceptable in most applications. However, it can fail under some worst case conditions. To assure proper operation, see the TMS320F2837xD Real-Time Dual-Core MCUs Silicon Errata. This issue was fixed in R1.1a and later revision controlCARDs.
  • Several name changes were made to pins on the device and are now reflected in R1.1a controlCARD documentation. No functionality was affected.

Warnings about R1.1a and earlier F28377D controlCARDs:

  • The circuitry used to drive the C2000 MCU’s voltage references is not ideal. Instead, it is recommended that users use the voltage reference driving circuitry found in the R1.3 controlCARD.

Warnings about R1.3 of F28379D controlCARD:

  • R51-R54 were mistakenly populated with 100 MΩ resistors instead of 100 mΩ resistors. With 100 MΩ resistors used, the voltage references for the analog-to-digital converters (ADCs) may not be held adequately constant and the accuracy/precision of ADC results may be affected during sampling/conversion. It is recommended that customers replace R51-R54 with 100 mΩ, 0603, 5% tolerance (or better) resistors. For evaluation of the controlCARD in a lab environment, it is also acceptable to short R51-R54 using 0 Ω resistors or solder bridges, however, populating with 100 mΩ is preferred.
