MSP430I2040TRHBR from Texas Instruments, in a VQFN-32-EP(5x5). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0.0+ input SD24 positive analog input channel A0.0 (differential PGA input). Short unused analog input pairs together and connect to analog ground (AVSS).
2 A0.0- input SD24 negative analog input channel A0.0 (differential PGA input).
3 A1.0+ input SD24 positive analog input channel A1.0 (differential PGA input).
4 A1.0- input SD24 negative analog input channel A1.0 (differential PGA input).
5 A2.0+ input SD24 positive analog input channel A2.0 (differential PGA input).
6 A2.0- input SD24 negative analog input channel A2.0 (differential PGA input).
7 A3.0+ input SD24 positive analog input channel A3.0 (differential PGA input).
8 A3.0- input SD24 negative analog input channel A3.0 (differential PGA input).
9 VREF passive SD24 external reference voltage input. When SD24 operates with internal reference (SD24REFS=1), leave VREF unloaded except for the recommended C_VREF decoupling capacitor to AVSS.
10 AVSS power_in Analog supply voltage negative terminal (analog ground).
11 ROSC passive External resistor pin for the DCO. In external-resistor mode, connect the recommended resistor between ROSC and AVSS; in internal-resistor mode, tie ROSC to AVSS.
12 DVSS power_in Digital supply voltage negative terminal (digital ground). TI recommends bonding the RHB package thermal pad to DVSS.
13 VCC power_in Analog and digital supply voltage positive terminal. Operating range 2.2 V to 3.6 V.
14 VCORE passive Regulated 1.8 V core supply output (internal use only, no external current loading). Connect only the recommended C_VCORE decoupling capacitor.
15 RST/NMI/SBWTDIO bidirectional Reset or non-maskable interrupt input; also Spy-Bi-Wire test data input/output for device programming and debug. Terminate with a 47 kohm pullup to VCC and 10 nF (or 2.2 nF) pulldown.
16 TEST/SBWTCK input Selects JTAG test mode on pins P1.0-P1.3 and serves as the Spy-Bi-Wire test clock input for device programming and debug. Has an internal pulldown.
17 P1.0/UCA0STE/MCLK/TCK bidirectional GPIO P1.0; alternate functions eUSCI_A0 SPI slave-transmit-enable, MCLK output, and JTAG test clock (TCK) for programming/debug.
18 P1.1/UCA0CLK/SMCLK/TMS bidirectional GPIO P1.1; alternate functions eUSCI_A0 clock, SMCLK output, and JTAG test-mode select (TMS).
19 P1.2/UCA0RXD/UCA0SOMI/ACLK/TDI/TCLK bidirectional GPIO P1.2; eUSCI_A0 UART RXD or SPI slave-out/master-in, ACLK output, and JTAG TDI / TCLK for programming/debug.
20 P1.3/UCA0TXD/UCA0SIMO/TA0CLK/TDO/TDI bidirectional GPIO P1.3; eUSCI_A0 UART TXD or SPI slave-in/master-out, Timer_A0 external clock (TACLK), and JTAG TDO / TDI programming pin.
21 P1.4/UCB0STE/TA0.0 bidirectional GPIO P1.4; eUSCI_B0 SPI slave-transmit-enable and Timer_A0 CCR0 capture (CCI0A) / compare (Out0).
22 P1.5/UCB0CLK/TA0.1 bidirectional GPIO P1.5; eUSCI_B0 clock and Timer_A0 CCR1 capture (CCI1A) / compare (Out1).
23 P1.6/UCB0SCL/UCB0SOMI/TA0.2 bidirectional GPIO P1.6; eUSCI_B0 I2C clock (SCL) or SPI slave-out/master-in, and Timer_A0 CCR2 capture (CCI2A) / compare (Out2).
24 P1.7/UCB0SDA/UCB0SIMO/TA1CLK bidirectional GPIO P1.7; eUSCI_B0 I2C data (SDA) or SPI slave-in/master-out, and Timer_A1 external clock (TACLK).
25 P2.0/TA1.0/CLKIN bidirectional GPIO P2.0; Timer_A1 CCR0 capture (CCI0A) / compare (Out0); DCO bypass clock input (CLKIN).
26 P2.1/TA1.1 bidirectional GPIO P2.1; Timer_A1 CCR1 capture (CCI1A) / compare (Out1).
27 P2.2/TA1.2 bidirectional GPIO P2.2; Timer_A1 CCR2 capture (CCI2A) / compare (Out2).
28 P2.3/VMONIN bidirectional GPIO P2.3; also voltage monitor analog input (VMONIN) for the supply voltage monitor.
29 P2.4/TA1.0 bidirectional GPIO P2.4; Timer_A1 CCR0 capture (CCI0B) / compare (Out0). Available only on the RHB package.
30 P2.5/TA0.0 bidirectional GPIO P2.5; Timer_A0 CCR0 capture (CCI0B) / compare (Out0). Available only on the RHB package.
31 P2.6/TA0.1 bidirectional GPIO P2.6; Timer_A0 CCR1 compare (Out1). Available only on the RHB package.
32 P2.7/TA0.2 bidirectional GPIO P2.7; Timer_A0 CCR2 compare (Out2). Available only on the RHB package.
33 EP power_in Exposed thermal pad on the underside of the RHB VQFN package. TI recommends connecting the thermal pad to DVSS.
