TMS320F280230PTT from Texas Instruments, in a LQFP-48(7x7). 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; PWM pin pullups are not enabled at reset.
38 GPIO3/EPWM2B/COMP2OUT bidirectional General-purpose I/O 3 with ePWM2B output and direct Comparator 2 output COMP2OUT (48-pin device) functions.
39 GPIO4/EPWM3A bidirectional General-purpose I/O 4 with ePWM3A output function.
40 GPIO5/EPWM3B/ECAP1 bidirectional General-purpose I/O 5 with ePWM3B output and enhanced capture 1 input/output (ECAP1) functions.
41 GPIO6/EPWMSYNCI/EPWMSYNCO bidirectional General-purpose I/O 6 with ePWM external sync input EPWMSYNCI and sync output EPWMSYNCO functions.
42 GPIO7/SCIRXDA bidirectional General-purpose I/O 7 with SCI-A receive data input function.
43 VDD power_in CPU and logic digital power pin, with the same 1.2-µF minimum ceramic capacitor requirement when the internal VREG is used.
44 VSS power_in Digital ground pin.
45 X1 input On-chip crystal oscillator input; 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.
