MSP430G2432IPW20R

Texas Instruments · Microcontrollers (MCU/MPU/SOC) · TSSOP-20

MSP430G2432IPW20R from Texas Instruments, in a TSSOP-20. 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 DVCC power_in Digital supply voltage input; the device operating supply range is stated as 1.8 V to 3.6 V.
2 P1.0/TA0CLK/ACLK/A0 bidirectional General-purpose digital I/O that can also serve as Timer0_A TACLK input, ACLK output, or ADC10 analog input A0 (ADC10 functions are available only on MSP430G2x32 devices).
3 P1.1/TA0.0/A1 bidirectional General-purpose digital I/O that can also serve as Timer0_A capture input CCI0A or compare output Out0, or ADC10 analog input A1.
4 P1.2/TA0.1/A2 bidirectional General-purpose digital I/O that can also serve as Timer0_A capture input CCI1A or compare output Out1, or ADC10 analog input A2.
5 P1.3/ADC10CLK/A3/VREF-/VEREF- bidirectional General-purpose digital I/O that can also serve as ADC10 conversion clock output, ADC10 analog input A3, or ADC10 negative reference voltage.
6 P1.4/TA0.2/SMCLK/A4/VREF+/VEREF+/TCK bidirectional General-purpose digital I/O that can also serve as Timer0_A capture input CCI2A or compare output Out2, SMCLK output, ADC10 analog input A4, ADC10 positive reference voltage, or JTAG test clock TCK for device programming and test.
7 P1.5/TA0.0/SCLK/A5/TMS bidirectional General-purpose digital I/O that can also serve as Timer0_A compare output Out0, USI clock input in I2C mode or clock input/output in SPI mode, ADC10 analog input A5, or JTAG test mode select TMS.
8 P2.0 bidirectional General-purpose digital I/O with Schmitt-trigger input; its pulldown resistor should be enabled by setting P2REN.0 = 1.
9 P2.1 bidirectional General-purpose digital I/O with Schmitt-trigger input; its pulldown resistor should be enabled by setting P2REN.1 = 1.
10 P2.2 bidirectional General-purpose digital I/O with Schmitt-trigger input; its pulldown resistor should be enabled by setting P2REN.2 = 1.
11 P2.3 bidirectional General-purpose digital I/O with Schmitt-trigger input; its pulldown resistor should be enabled by setting P2REN.3 = 1.
12 P2.4 bidirectional General-purpose digital I/O with Schmitt-trigger input; its pulldown resistor should be enabled by setting P2REN.4 = 1.
13 P2.5 bidirectional General-purpose digital I/O with Schmitt-trigger input; its pulldown resistor should be enabled by setting P2REN.5 = 1.
14 P1.6/TA0.1/SDO/SCL/A6/TDI/TCLK bidirectional General-purpose digital I/O that can also serve as Timer0_A compare output Out1, USI data output (SPI) or clock (I2C SCL), ADC10 analog input A6, or JTAG test data input/test clock input TDI/TCLK.
15 P1.7/SDI/SDA/A7/TDO/TDI bidirectional General-purpose digital I/O that can also serve as USI data input (SPI) or data (I2C SDA), ADC10 analog input A7, or JTAG test data output TDO / test data input TDI.
16 RST/NMI/SBWTDIO input Active-low device reset, or nonmaskable interrupt input, or Spy-Bi-Wire test data input/output during programming and test.
17 TEST/SBWTCK input Selects test mode for the JTAG pins on Port 1 (the device protection fuse is connected to TEST), and serves as Spy-Bi-Wire test clock input during programming and test.
18 XOUT/P2.7 bidirectional Output terminal of the crystal oscillator, or general-purpose digital I/O P2.7; if used as an input, excess current flows until P2SEL.7 is cleared because the oscillator output driver remains connected after reset.
19 XIN/P2.6/TA0.1 bidirectional Input terminal of the crystal oscillator, or general-purpose digital I/O P2.6 that can also serve as Timer0_A compare output Out1.
20 DVSS power_in Digital ground reference.
