F280049 controlCARD Installed on TMDSHSECDOCK The Piccolo F280049 controlCARD from Texas Instruments (TI) provides a great way to learn and experiment with the F28004x device family within TI’s C2000 family of microcontrollers (MCUs). This controlCARD uses the 120HSEC connector (compatible with the TMDSHSECDOCK docking station) and is intended to provide a well-filtered robust design capable of working in most environments. This document describes the hardware details of the F280049 controlCARD and explains the functions, locations of jumpers, and connectors present on the board. The Hardware Developer’s Kit, which is a full set of files necessary to evaluate and develop with the F280049 device, can be found in C2000Ware and includes: • • • • Schematics – designed in Altium Bill of materials (BOM) Layout PCB files – designed in Altium Gerber files NOTE: This kit is designed to explore the functionality of the F28004x microcontroller family. The controlCARD can be treated as a good reference design, but it is not intended to be a complete customer design. Full compliance to safety, EMI/EMC, and other regulations are left to the designer of the final customer system. 2 Piccolo F280049 controlCARD Information Guide Copyright © 2017–2018, Texas Instruments Incorporated SPRUIC4B – July 2017 – Revised July 2018 Submit Documentation Feedback Errata www.ti.com This controlCARD can be obtained by ordering one of the products from Table 1. Table 1. F280049 controlCARD Part Numbers 2 Part Number Status Description TMDXDOCK280049M Experimental XF280049M controlCARD and HSEC docking station bundle TMDSDOCK280049C Qualified F280049C controlCARD and HSEC docking station bundle TMDSCNCD280049C Qualified F280049C controlCARD Errata Current revision of controlCARD as of June, 2018: PCB rev - B, ASSY rev - none. 2.1 Warnings, Notes, and Errata Notes for all controlCARDs: • The docking station is capable of drawing power through the included USB cable. However, when external components are added to the docking station for experimentation, the system may require more power than a standard USB port can provide (5-V and 500-mA). This is especially true when additional circuitry has been added to the docking station. In such cases, an external 5-VDC power supply (2.5-mm inner diameter × 5.5-mm outer diameter) plugged into J1 is recommended. A compatible supply could be the: Phihong PSAC05R-050(P)-R-C2 + Phihong RPBAG. • The F28004x by default expects GPIO24 and GPIO32 to be the input pins responsible for determining the device boot mode at power up; the external pull directions for GPIO24 and GPIO32 are configured with S1 (see Table 4). If desired, the GPIO pins used for boot mode selection can be modified by programming the OTP in the device. Refer to the Boot ROM section of the specific device’s Technical Reference Manual (TRM) for more information. • The controlCARD included with TMDXDOCK280049M uses prototype silicon XF280049M. XF280049M is a prototype variant only, and is not offered in production. It has the same functionality and configuration as the qualified variant F280049C. 3 Getting Familiar With the controlCARD 3.1 F280049 controlCARD Features • • • • • • • 3.2 Piccolo F280049 Microcontroller – High performance C2000 microcontroller 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 TMDSHSECDOCK. 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-VDC supply provides power to onboard 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. F28004x Device Description For a complete description of the F28004x devices, see Section 1.3 of the TMS320F28004x Piccolo™ Microcontrollers data sheet (SPRS945).

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-VDC 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. Based on the way that the controlCARD is used, additional hardware settings may be necessary, as shown in Table 2. Table 2.

This software package includes many example projects which allow the user to experiment with the ADC, PWM, and other C2000 peripherals. Support files for both register-level and driver-level programming are included with C2000Ware: • Register programming examples are located at: \ti\c2000\C2000Ware_XXXX\device_support\f28004x\examples • Driverlib programming examples are located at: \ti\c2000\C2000Ware_XXXX\driverlib\f28004x\examples 4 Special Notes 4.1 XDS100v2 Emulator and SCI/UART Connectivity The F280049 controlCARD provides on-board emulation and USB-to-UART adapter functionality. This allows for a convenient method to debug and demo the F280049 MCU. The FTDI chip, its support circuitry, and associated isolation components are placed in Macro A, the left section of the controlCARD. Each of these components contains an additional A within the component reference designator (that is R2:A for resistor 2 in Macro A). Each F280049 controlCARD’s XDS100v2 is programmed with a fixed serial number. If a debug session must involve two or more F280049 controlCARDs, each controlCARDs must have a unique serial number, and some must be reprogrammed. See: http://processors.wiki.ti.com/index.php/XDS100#Q:_Can_I_change_the_serial_number_on_my_XDS100v2 .3F. The configuration of the switches on S1:A (shown in Figure 2) determine whether the onboard emulator is active, whether an external emulator can be used, or whether the device will boot from FLASH/peripherals. Figure 2. XDS100v2 Emulation Circuitry and Isolation Circuitry is Denoted by :A 4.2 cJTAG Usage The F280049 MCU supports the cJTAG 2-pin debugging interface, but the onboard XDS100v2 emulator does not. To experiment with cJTAG, an external emulator must be connected through the baseboard. To enable cJTAG: 1. Connect an external emulator to the controlCARD's baseboard. 2. Change S4 to the cJTAG position (switch flipped up). 3. If cJTAG is used, the F280049 MCU will have two additional GPIOs which can be used by the application. Configure S2 and S3, as desired, to control which controlCARD fingers or pins the newly available GPIOs are connected to.

Instead of shorting PGA6_OF and PGA6_IN, the PGA6_OF signal may be accessed from the HSEC connector independently of the PGA6_IN signal. NOTE: The PGA RFILTER resistor should never be enabled while the S7 switch is closed. Prolonged exposure to contention between the PGA_IN and PGA_OF pins may result in permanent damage to the internal RFILTER resistor. 6 Piccolo F280049 controlCARD Information Guide Copyright © 2017–2018, Texas Instruments Incorporated SPRUIC4B – July 2017 – Revised July 2018 Submit Documentation Feedback Special Notes www.ti.com 4.4 Evaluation of the Internal DC/DC Converter The controlCARD, by default, assumes the F280049 internal VREG will be used to generate the 1.2-V power supply required by the MCU. The controlCARD enables the user to use the internal DC/DC converter capabilities, with some soldering. To • • • • enable the internal DC/DC converter: R18 and R19 must be unpopulated. R21 and R22 must be populated with a 0-Ω resistor. C19 must be populated with a 2.2-µF X5R/X7R capacitor. C20 and C21 must each be populated with a 10-µF X5R/X7R capacitor. Functionally, the F280049 powers up the 1.2-V power rail using the internal VREG, then requires software to change from the VREG to the DC/DC. See the F28004x Technical Reference Manual for more details.

The internal DC/DC cannot be used. • R18,R19 unpopulated and R21,R22 populated with 0-Ω resistors – Internal DC/DC can be used to generate the 1.2-V VDD power rail. GPIO22 and GPIO23 are used as VFBSW and VSW, respectively. The internal DC/DC can be used. C19, C20, C21 These capacitors should be populated when the F280049’s internal DC/DC capability is used. C19 should be populated with a 2.2-µF capacitor. C20 and C21 should each be populated with a 10-µF capacitor. R24, C28 R24 and C28 create an optional snubber circuit, which can be used if the DC/DC is used. R36-R47,R49,R53, R60-R64, C41-C47, and C48-C59 Optional RC input filter for all ADC/PGA inputs C34-C40 PGA filter capacitor when PGA filtering is used R55-R59 PGA-GND configuration resistors R48,R50-R52,R54 These resistors control whether the negative input (PGAGND) for each PGA are grounded locally or whether they should be grounded through pins on the HSEC connector (for use in Kelvin grounding). By default, resistors R55-R59 are not populated and R48, R50-R52, R54 are populated. Because of this, all the PGAs are, by default, expected to be referenced to ground by the baseboard. If, for example, R55 was populated and R48 was unpopulated, then PGA1’s PGAGND would be grounded on the controlCARD.

S7 PGA Filter Configuration Switches From the left, the switches control whether PGA1-PGA7’s outputs, respectively, are filtered. The eighth switch of S7 is not used. Each switch: • In the up position – an HSEC pin is connected to the respective PGA+ input pin, and is now also tied to an additional ADC input pin. In software, PGA output filtering, for the respective PGA, functionality should NOT be used. • In the down position – an HSEC pin only goes to the PGA+ input pin. PGA output filtering, for the respective PGA, may be used. The up position for S7’s switch 6 (PGA6) is implemented differently from the other PGAs. PGA6_OF may be accessed through the HSEC connector independently of PGA6_IN, whereas the other PGAs will have their respective PGAn_OF and PGAn_IN signals shorted together.

S1:A Isolated emulation and UART communication enable switches Left (Switch 1) – JTAG Enable: • Up (on) – All signals between the XDS100v2 emulation logic and the MCU are connected. This setting is valid when the MCU is being debugged or programmed through the on-card XDS100v2 emulator. • Down (off) – The XDS100v2 emulation logic will NOT be connected to the MCU. This setting is valid when the device boots from FLASH, boots from a peripheral directly, or when an external JTAG emulator is used. Right (Switch 2) – ISO UART communication enable: • Up (on) – The C2000 MCU’s GPIO-28 (and pin76 of the 180pin controlCARD connector) are coupled to the FTDI’s USB-to-Serial adapter. This allows UART communication to a computer through the FTDI chip. However, in this position, GPIO-28 is forced high by the FTDI chip. Functionality of pin76 on the connector is limited. • Down (off) – The C2000 MCU will NOT be connected to the FTDI USB-to-Serial adapter. Pin76 of the 180pin controlCARD connector is directly connected to GPIO-28. 10 Piccolo F280049 controlCARD Information Guide Copyright © 2017–2018, Texas Instruments Incorporated SPRUIC4B – July 2017 – Revised July 2018 Submit Documentation Feedback Hardware References www.ti.com Table 4.
