4.1 F28388D controlCARD Features

• F28388D 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. Setting a switch allows an external JTAG emulator to be used.
• Connectivity – The controlCARD contains connectors that allow you to experiment with USB, a microSD card, and isolated universal asynchronous receiver/transmitter (UART)/SCI with the F2838x 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 the ADC input pins.

The controlCARD uses DP83822 10/100M Ethernet PHY for EtherCAT communication. This PHY has low round trip (TX+RX) latency of 242 ns and robust EMI/EMC performance. DP83826E/I is an alternative 10/100M Ethernet PHY and is also recommended for use with F2838x devices. DP83826E has a reduced and more deterministic latency of < 216 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 suitable for real time applications.
