MSP430G2402IPW20R from Texas Instruments, in a TSSOP-20. 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 DVCC power_in Positive digital supply voltage, rated 1.8 V to 3.6 V for normal operation
2 P1.0/TA0CLK/ACLK/A0 bidirectional Port 1 I/O bit 0; selectable as Timer0_A clock input (TA0CLK), ACLK signal output, or ADC10 analog input A0 (MSP430G2x32 only)
3 P1.1/TA0.0/A1 bidirectional Port 1 I/O bit 1; selectable as Timer0_A capture/compare output (TA0.0) or ADC10 analog input A1 (MSP430G2x32 only)
4 P1.2/TA0.1/A2 bidirectional Port 1 I/O bit 2; selectable as Timer0_A capture/compare output (TA0.1) or ADC10 analog input A2 (MSP430G2x32 only)
5 P1.3/ADC10CLK/A3/VREF-/VEREF- bidirectional Port 1 I/O bit 3; selectable as ADC10 conversion clock output, ADC10 analog input A3, or negative reference voltage (MSP430G2x32 only)
6 P1.4/TA0.2/SMCLK/A4/VREF+/VEREF+/TCK bidirectional Port 1 I/O bit 4; selectable as Timer0_A capture/compare output (TA0.2), SMCLK signal output, ADC10 analog input A4 (MSP430G2x32 only), positive reference voltage (MSP430G2x32 only), or JTAG test clock input
7 P1.5/TA0.0/A5/SCLK/TMS bidirectional Port 1 I/O bit 5; selectable as Timer0_A output (TA0.0), ADC10 analog input A5 (MSP430G2x32 only), USI serial clock, or JTAG test mode select
8 P2.0 bidirectional Port 2 I/O bit 0 with edge-selectable interrupt capability and programmable pull-down resistor
9 P2.1 bidirectional Port 2 I/O bit 1 with edge-selectable interrupt capability and programmable pull-down resistor
10 P2.2 bidirectional Port 2 I/O bit 2 with edge-selectable interrupt capability and programmable pull-down resistor
11 P2.3 bidirectional Port 2 I/O bit 3 with edge-selectable interrupt capability and programmable pull-down resistor
12 P2.4 bidirectional Port 2 I/O bit 4 with edge-selectable interrupt capability and programmable pull-down resistor
13 P2.5 bidirectional Port 2 I/O bit 5 with edge-selectable interrupt capability and programmable pull-down resistor
