Delfino™ TMS320F28379D controlCARD R1.3
–
Change the boot mode to Get Mode and configure the OTP such that SCIBoot IOOption2 is called.
This is really only an option if you always want to boot from SCI or Parallel GPIO, because you will
be overwriting your ability to boot from Flash.
–
With an emulator connected (TRSTn = 1), registers can be set such that SCIBoot’s IOOption2 boot
mode is called.
For more information, see the device-specific TRM.
•
R83 on the controlCARD is populated to allow a customer to evaluate the controlCARD without a
baseboard if desired. Because R83 is populated, the controlCARD putd more capacitance on the USB
5V supply than the USB specification allows. R83 should be removed in order to meet the
specification.

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 Dual-Core Delfino™
. 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 M
Ω
resistors instead of 100 m
Ω
resistors. With 100 M
Ω
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 m
Ω
, 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 m
Ω
is
preferred. For more information, see the following E2E post:

Getting Familiar With the controlCARD
3.1
F28379D controlCARD Features
•
Delfino F28379D Microcontroller – High performance C2000 microcontroller is located on the
controlCARD.
•
180-pin HSEC8 Edge Card Interface – Allows for compatibility with all of C2000’s 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 xds100v2 emulator provides a convenient interface to Code
Composer Studio™ without additional hardware. Flipping a switch allows an external JTAG emulator to
be used.
