NOTE

The exposed lead frame die pad of the PowerPAD™ package serves two functions: to remove heat from the die and to provide ground path for the digital ground (analog ground is provided through dedicated pins). Thus, the PowerPAD should be soldered to the ground (GND) plane of the PCB because this will provide both the digital ground path and good thermal conduction path. To make optimum use of the thermal efficiencies designed into the PowerPAD package, the PCB must be designed with this technology in mind. A thermal land is required on the surface of the PCB directly underneath the body of the PowerPAD. The thermal land should be soldered to the exposed lead frame die pad of the PowerPAD package; the thermal land should be as large as needed to dissipate the required heat. An array of thermal vias should be used to connect the thermal pad to the internal GND plane of the board. See PowerPAD™ Thermally Enhanced Package for more details on using the PowerPAD package.

NOTE

PCB footprints and schematic symbols are available for download in a vendor-neutral format, which can be exported to the leading EDA CAD/CAE design tools. See the CAD/CAE Symbols section in the product folder for each device, under the Packaging section. These footprints and symbols can also be searched for at http://webench.ti.com/cad/.

3.2 Signal Descriptions

Table 3-1 describes the signals. The GPIO function is the default at reset, unless otherwise mentioned. The peripheral signals that are listed under them are alternate functions. Some peripheral functions may not be available in all devices. All GPIO pins are I/O/Z and have an internal pullup, which can be selectively enabled or disabled on a per-pin basis. This feature only applies to the GPIO pins. The pullups are not enabled at reset.

RESET
XRS F19 124 I/OD Device Reset (in) and Watchdog Reset (out). The devices have a built-in power-on reset (POR) circuit. During a power-on condition, this pin is driven low by the device. An external circuit may also drive this pin to assert a device reset. This pin is also driven low by the MCU when a watchdog reset or NMI watchdog reset occurs. During watchdog reset, the XRS pin is driven low for the watchdog reset duration of 512 OSCCLK cycles. A resistor with a value from 2.2 kΩ to 10 kΩ should be placed between XRS and VDDIO. If a capacitor is placed between XRS and VSS for noise filtering, it should be 100 nF or smaller. These values will allow the watchdog to properly drive the XRS pin to VOL within 512 OSCCLK cycles when the watchdog reset is asserted. The output buffer of this pin is an open drain with an internal pullup. If this pin is driven by an external device, an open-drain device is recommended.
CLOCKS
X1 G19 123 I On-chip crystal-oscillator input. To use this oscillator, a quartz crystal must be connected across X1 and X2. If this pin is not used, it must be tied to GND.
This pin can also be used to feed a single-ended 3.3-V level clock. In this case, X2 is a No Connect (NC).
X2 J19 121 O On-chip crystal-oscillator output. A quartz crystal may be connected across X1 and X2. If X2 is not used, it must be left unconnected.
NO CONNECT
NC H4 — No connect. BGA ball is electrically open and not connected to the die.
JTAG
TCK V15 81 I JTAG test clock with internal pullup (see Section 4.5)
TDI W13 77 I JTAG test data input (TDI) with internal pullup. TDI is clocked into the selected register (instruction or data) on a rising edge of TCK.
TDO W15 78 O/Z JTAG scan out, test data output (TDO). The contents of the selected register (instruction or data) are shifted out of TDO on the falling edge of TCK.(3)
TMS W14 80 I JTAG test-mode select (TMS) with internal pullup. This serial control input is clocked into the TAP controller on the rising edge of TCK.
TRST V14 79 I JTAG test reset with internal pulldown. TRST, when driven high, gives the scan system control of the operations of the device. If this signal is driven low, the device operates in its functional mode, and the test reset signals are ignored. NOTE: TRST must be maintained low at all times during normal device operation. An external pulldown resistor is required on this pin. The value of this resistor should be based on drive strength of the debugger pods applicable to the design. A 2.2-kΩ or smaller resistor generally offers adequate protection. The value of the resistor is application-specific. TI recommends that each target board be validated for proper operation of the debugger and the application. This pin has an internal 50-ns (nominal) glitch filter.
INTERNAL VOLTAGE REGULATOR CONTROL

ANALOG, DIGITAL, AND I/O POWER
VDD E9 16 1.2-V digital logic power pins. TI recommends placing a decoupling capacitor near each VDD pin with a minimum total capacitance of approximately 20 uF. The exact value of the decoupling capacitance should be determined by your system voltage regulation solution.

TEST PINS
FLT1 W12 73 I/O Flash test pin 1. Reserved for TI. Must be left unconnected.
FLT2 V13 74 I/O Flash test pin 2. Reserved for TI. Must be left unconnected.
  1. I = Input, O = Output, OD = Open Drain, Z = High Impedance
  2. High-Speed SPI-enabled GPIO mux option. This pin mux option is required when using the SPI in High-Speed Mode (HS_MODE = 1 in SPICCR). This mux option is still available when not using the SPI in High-Speed Mode (HS_MODE = 0 in SPICCR).
  3. This pin has output impedance that can be as low as 22 Ω. This output could have fast edges and ringing depending on the system PCB characteristics. If this is a concern, the user should take precautions such as adding a 39 Ω (10% tolerance) series termination resistor or implement some other termination scheme. It is also recommended that a system-level signal integrity analysis be performed with the provided IBIS models. The termination is not required if this pin is used for input function.

3.3 Pins With Internal Pullup and Pulldown

Some pins on the device have internal pullups or pulldowns. Table 3-2 lists the pull direction and when it is active. The pullups on GPIO pins are disabled by default and can be enabled through software. In order to avoid any floating unbonded inputs, the Boot ROM will enable internal pullups on GPIO pins that are not bonded out in a particular package. Other pins noted in Table 3-2 with pullups and pulldowns are always on and cannot be disabled.

3.4 Pin Multiplexing

3.4.1 GPIO Muxed Pins

Table 3-3 shows the GPIO muxed pins. The default for each pin is the GPIO function, secondary functions can be selected by setting both the GPyGMUXn.GPIOz and GPyMUXn.GPIOz register bits. The GPyGMUXn register should be configured prior to the GPyMUXn to avoid transient pulses on GPIO's from alternate mux selections. Columns not shown and blank cells are reserved GPIO Mux settings.

(1) I = Input, O = Output, OD = Open Drain
(2) GPIO Index settings of 9, 10, 11, 13, and 14 are reserved.
(3) High-Speed SPI-enabled GPIO mux option. This pin mux option is required when using the SPI in High-Speed Mode (HS_MODE = 1 in SPICCR). This mux option is still available when not using the SPI in High-Speed Mode (HS_MODE = 0 in SPICCR).

3.4.2 Input X-BAR

The Input X-BAR is used to route any GPIO input to the ADC, eCAP, and ePWM peripherals as well as to external interrupts (XINT) (see Figure 3-6). Table 3-4 shows the input X-BAR destinations. For details on configuring the Input X-BAR, see the Crossbar (X-BAR) chapter of the TMS320F2837xD Dual-Core Delfino Microcontrollers Technical Reference Manual.

3.4.3 Output X-BAR and ePWM X-BAR

The Output X-BAR has eight outputs which can be selected on the GPIO mux as OUTPUTXBARx. The ePWM X-BAR has eight outputs which are connected to the TRIPx inputs of the ePWM. The sources for both the Output X-BAR and ePWM X-BAR are shown in Figure 3-7. For details on the Output X-BAR and ePWM X-BAR, see the Crossbar (X-BAR) chapter of the TMS320F2837xD Dual-Core Delfino Microcontrollers Technical Reference Manual.

3.4.4 USB Pin Muxing

Table 3-5 shows assignment of the alternate USB function mapping. These can be configured with the GPBAMSEL register.

Table 3-5 Alternate USB Function

GPIO GPBAMSEL SETTING USB FUNCTION
GPIO42 GPBAMSEL[10] = 1b USB0DM
GPIO43 GPBAMSEL[11] = 1b USB0DP

3.4.5 High-Speed SPI Pin Muxing

The SPI module on this device has a high-speed mode. To achieve the highest possible speed, a special GPIO configuration is used on a single GPIO mux option for each SPI. These GPIOs may also be used by the SPI when not in high-speed mode (HS_MODE = 0).

To select the mux options that enable the SPI high-speed mode, configure the GPyGMUX and GPyMUX registers as shown in Table 3-6.

For applications that do not need to use all functions of the device, Table 3-7 lists acceptable conditioning for any unused pins. When multiple options are listed in Table 3-7, any are acceptable. Pins not listed in Table 3-7 must be connected according to Table 3-1.
