Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GPIO29/SCITXDA/SCLA/TZ3 | bidirectional | General-purpose I/O 29 (default GPIO at reset) with alternate SCI-A transmit, I2C clock SCLA (open-drain) and trip-zone 3 input functions; inputs are not 5-V tolerant. |+| 2 | TRST | input | JTAG test reset with internal pulldown that must be kept low during normal operation, and an external pulldown resistor is required (2.2 kΩ generally offers adequate protection). |+| 3 | XRS | bidirectional | Device reset input and watchdog reset output, open-drain with internal pullup, driven low during power-on/brown-out and for 512 OSCCLK cycles on a watchdog reset; an R-C circuit is recommended for noise immunity. |+| 4 | ADCINA6/AIO6 | passive | ADC Group A channel 6 analog input, or digital analog I/O AIO6 when selected; AIO pins have no internal pullup. |+| 5 | ADCINA4/COMP2A/AIO4 | passive | ADC Group A channel 4 analog input, Comparator 2A input (48-pin device), or digital analog I/O AIO4; AIO pins have no internal pullup. |+| 6 | VSSA | power_in | Analog ground pin. |+| 7 | VSSA | power_in | Analog ground pin. |+| 8 | ADCINA1 | passive | ADC Group A channel 1 analog input. |+| 9 | ADCINA2/COMP1A/AIO2 | passive | ADC Group A channel 2 analog input, Comparator 1A input, or digital analog I/O AIO2; AIO pins have no internal pullup. |+| 10 | VREFHI | input | ADC external high reference, used only in external reference mode, and must not exceed VDDA. |+| 11 | VDDA | power_in | Analog power pin, recommended 2.97 V to 3.63 V (3.3 V nominal), tied with a 2.2-µF (typical) capacitor close to the pin and kept within approximately 0.3 V of VDDIO. |+| 12 | VSSA/VREFLO | power_in | Analog ground pin that doubles as the ADC low reference VREFLO, which is always tied to ground. |+| 13 | ADCINB1 | passive | ADC Group B channel 1 analog input. |+| 14 | ADCINB2/COMP1B/AIO10 | passive | ADC Group B channel 2 analog input, Comparator 1B input, or digital analog I/O AIO10; AIO pins have no internal pullup. |+| 15 | VSSA | power_in | Analog ground pin. |+| 16 | ADCINB4/COMP2B/AIO12 | passive | ADC Group B channel 4 analog input, Comparator 2B input (48-pin device), or digital analog I/O AIO12; AIO pins have no internal pullup. |+| 17 | ADCINB6/AIO14 | passive | ADC Group B channel 6 analog input, or digital analog I/O AIO14; AIO pins have no internal pullup. |+| 18 | VSSA | power_in | Analog ground pin. |+| 19 | GPIO34/COMP2OUT | bidirectional | General-purpose I/O 34 with direct Comparator 2 output COMP2OUT; pin may glitch during power-up when the on-chip VREG is used. |+| 20 | GPIO35 (TDI) | bidirectional | General-purpose I/O 35 with JTAG test data input TDI (internal pullup); pin may glitch during power-up when the on-chip VREG is used. |+| 21 | GPIO36 (TMS) | bidirectional | General-purpose I/O 36 with JTAG test-mode select TMS (internal pullup), clocked into the TAP controller on the rising edge of TCK; pin may glitch during power-up when the on-chip VREG is used. |+| 22 | GPIO37/TDO | bidirectional | General-purpose I/O 37 with JTAG test data output TDO, shifted out on the falling edge of TCK with 8-mA drive; pin may glitch during power-up when the on-chip VREG is used. |+| 23 | GPIO38/XCLKIN (TCK) | bidirectional | General-purpose I/O 38 with JTAG test clock TCK (internal pullup) and external oscillator input XCLKIN; do not enable the XCLKIN clock path while TCK is active during JTAG debug. |+| 24 | GPIO18/SPICLKA/SCITXDA/XCLKOUT | bidirectional | General-purpose I/O 18 with SPI-A clock, SCI-A transmit and XCLKOUT functions; XCLKOUT is SYSCLKOUT, /2 or /4 (SYSCLKOUT/4 at reset) and requires the GPIO18 mux set to XCLKOUT. |+| 25 | GPIO19/XCLKIN/SPISTEA/SCIRXDA/ECAP1 | bidirectional | General-purpose I/O 19 with SPI-A STE, SCI-A receive, ECAP1 and external oscillator input XCLKIN functions; the XCLKIN path is not gated by the pin mux, so it must not be enabled when the pin is used for other peripherals. |+| 26 | GPIO17/SPISOMIA/TZ3 | bidirectional | General-purpose I/O 17 with SPI-A slave-out/master-in and trip-zone 3 input functions. |+| 27 | GPIO16/SPISIMOA/TZ2 | bidirectional | General-purpose I/O 16 with SPI-A slave-in/master-out and trip-zone 2 input functions. |+| 28 | GPIO1/EPWM1B/COMP1OUT | bidirectional | General-purpose I/O 1 with ePWM1B output and direct Comparator 1 output COMP1OUT functions; PWM pin pullups are not enabled at reset. |+| 29 | GPIO0/EPWM1A | bidirectional | General-purpose I/O 0 with ePWM1A output function; PWM pin pullups are not enabled at reset. |+| 30 | TEST | unconnected | Test pin reserved for TI that must be left unconnected. |+| 31 | GPIO32/SDAA/EPWMSYNCI/ADCSOCAO | bidirectional | General-purpose I/O 32 with I2C data SDAA (open-drain), ePWM external sync input and ADC start-of-conversion A output functions. |+| 32 | VDD | power_in | CPU and logic digital power pin; no external supply is needed with the internal VREG, which requires a 1.2-µF minimum ceramic capacitor (10% tolerance) to ground, and 1.71 V to 1.995 V must be supplied externally if VREG is disabled. |+| 33 | VSS | power_in | Digital ground pin. |+| 34 | VREGENZ | input | Internal voltage regulator enable input; pull low to enable the internal VREG and pull high to disable it. |+| 35 | VDDIO | power_in | Digital I/O and flash power pin, 2.97 V to 3.63 V (3.3 V nominal), the single supply source when VREG is enabled, tied with a 2.2-µF (typical) capacitor close to the pin. |+| 36 | GPIO33/SCLA/EPWMSYNCO/ADCSOCBO | bidirectional | General-purpose I/O 33 with I2C clock SCLA (open-drain), ePWM external sync output and ADC start-of-conversion B output functions. |+| 37 | GPIO2/EPWM2A | bidirectional | General-purpose I/O 2 with ePWM2A output function;

a quartz crystal or ceramic resonator is connected across X1 and X2, and the pin must be tied to GND if not used. |+| 46 | X2 | output | On-chip crystal oscillator output; a quartz crystal or ceramic resonator is connected across X1 and X2, and the pin must be left unconnected if not used. |+| 47 | GPIO12/TZ1/SCITXDA | bidirectional | General-purpose I/O 12 with trip-zone 1 input and SCI-A transmit output functions. |+| 48 | GPIO28/SCIRXDA/SDAA/TZ2 | bidirectional | General-purpose I/O 28 with SCI receive data, I2C data SDAA (open-drain) and trip-zone 2 input functions. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | LQFP-48(7x7) |+| Category | Embedded Processors & Controllers |+| Pins | 48 |++## CAD (KiCad official)++- Symbol: `TMS320F280230PTT`+- Footprint: `Package_QFP:LQFP-48_7x7mm_P0.5mm`+- 3D model: LQFP-48(7x7) (KiCad packages3D, STEP)+- 3D model files: `tms320f280230ptt-etched.step` / `tms320f280230ptt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready);
