TMS320F28034RSHS from Texas Instruments, in a VQFN-56-EP(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 GPIO22/EQEP1S/LINTXA bidirectional GPIO22 (I/O/Z, default at reset) with eQEP1 strobe or LIN transmit A alternate functions.
2 GPIO23/EQEP1I/LINRXA bidirectional GPIO23 (I/O/Z, default at reset) with eQEP1 index or LIN receive A alternate functions.
3 VDD power_in CPU and logic digital supply; with the internal VREG place a 1.2uF capacitor from each VDD pin to ground.
4 VSS power_in Digital ground.
5 XRS bidirectional Device reset input and watchdog reset output (open-drain with internal pullup, driven low by POR/BOR); use a 2.2k-10k resistor to VDDIO and at most 100nF to VSS.
6 TRST input JTAG test reset with internal pulldown; active high, must be held low in normal operation and needs an external pulldown per the datasheet (typically 2.2k).
7 ADCINA7 input ADC group A channel 7 input.
8 ADCINA6/COMP3A/AIO6 bidirectional ADC group A channel 6 input, comparator 3A input, or digital AIO6.
9 ADCINA4/COMP2A/AIO4 bidirectional ADC group A channel 4 input, comparator 2A input, or digital AIO4.
10 ADCINA3 input ADC group A channel 3 input.
11 ADCINA2/COMP1A/AIO2 bidirectional ADC group A channel 2 input, comparator 1A input, or digital AIO2.
12 ADCINA1 input ADC group A channel 1 input.
13 ADCINA0/VREFHI input ADC group A channel 0 input or external reference high (VREFHI); the two share this pin and cannot be used simultaneously, and VREFHI must not exceed VDDA.
14 VDDA power_in Analog supply; connect a 2.2uF (typical) capacitor near this pin; recommended 2.97V to 3.63V.
15 VSSA/VREFLO power_in Analog ground; VREFLO is always connected to VSSA on the RSH package.
16 ADCINB1 input ADC group B channel 1 input.
17 ADCINB2/COMP1B/AIO10 bidirectional ADC group B channel 2 input, comparator 1B input, or digital AIO10.
