Texas Instruments · Microcontrollers (MCU/MPU/SOC) · TSSOP-16

MSP430FR2311IPW16R from Texas Instruments, in a TSSOP-16. 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 P1.1/UCB0CLK/ACLK/C1/A1 bidirectional General-purpose digital I/O P1.1 (LVCMOS, powered from DVCC, high-impedance after BOR); alternate functions are eUSCI_B0 SPI clock I/O (UCB0CLK), ACLK output, eCOMP0 comparator input C1, and ADC analog input A1.
2 P1.0/UCB0STE/SMCLK/C0/A0/Veref+ bidirectional General-purpose digital I/O P1.0; alternate functions are eUSCI_B0 SPI slave transmit enable (UCB0STE), SMCLK output, eCOMP0 comparator input C0, ADC analog input A0, and ADC positive external reference input Veref+.
3 TEST/SBWTCK input Test-mode select input that enables the JTAG pin functions when driven high (internal pulldown always enabled; leave open if unused); also functions as the Spy-Bi-Wire clock input (SBWTCK) for 2-wire programming/debug.
4 RST/NMI/SBWTDIO bidirectional Active-low reset input (RST, default) that can be reconfigured as an edge-selectable non-maskable interrupt input (NMI); also serves as the bidirectional Spy-Bi-Wire data line (SBWTDIO) during 2-wire debug/programming; if unused, tie to DVCC through a 47-kΩ pullup with a 10-nF (or 1.1-nF for SBW) pulldown capacitor.
5 DVCC power_in Main digital/analog power-supply pin; recommended supply range is 1.8 V to 3.6 V with a 4.7 µF to 10 µF bulk capacitor plus a 100 nF low-ESR ceramic decoupling capacitor placed close to the pin.
6 DVSS power_in Digital and analog ground-supply pin (0 V reference for all other pin voltages).
7 P2.7/TB0CLK/XIN bidirectional General-purpose digital I/O P2.7 with pin-interrupt and LPM3.5/LPM4/LPM4.5 wake-up capability; alternate functions are Timer0_B3 external clock input (TB0CLK) and the crystal oscillator input terminal (XIN) for the LFXT/HFXT oscillator.
8 P2.6/MCLK/XOUT bidirectional General-purpose digital I/O P2.6; alternate functions are MCLK output and the crystal oscillator output terminal (XOUT) for the LFXT/HFXT oscillator.
9 P2.0/TB1.1/COUT bidirectional General-purpose digital I/O P2.0 with pin-interrupt and LPM3.5/LPM4/LPM4.5 wake-up capability; alternate functions are Timer1_B3 CCR1 capture/compare I/O (TB1.1) and the eCOMP0 comparator output (COUT).
10 P1.7/UCA0TXD/UCA0SIMO/TB0.2/TDO/TRI0+/A7/VREF+ bidirectional General-purpose digital I/O P1.7 (shared with JTAG; TI recommends disabling the pin interrupt during JTAG debug); alternate functions are eUSCI_A0 UART transmit (UCA0TXD) or SPI master-out data (UCA0SIMO), Timer0_B3 CCR2 capture/compare I/O (TB0.2), JTAG data output (TDO), TIA0 positive input (TRI0+), ADC analog input A7, and buffered 1.2-V reference voltage output (VREF+).
11 P1.6/UCA0RXD/UCA0SOMI/TB0.1/TDI/TCLK/A6 bidirectional General-purpose digital I/O P1.6 (shared with JTAG; TI recommends disabling the pin interrupt during JTAG debug); alternate functions are eUSCI_A0 UART receive (UCA0RXD) or SPI slave-out data (UCA0SOMI), Timer0_B3 CCR1 capture/compare I/O (TB0.1), JTAG data input (TDI) or test clock (TCLK), and ADC analog input A6; note the TRI0- (TIA0 negative input) function present on this pin for the PW20/RGY packages is not available on the TSSOP-16 package, which instead provides a dedicated low-leakage TRI0- pin (pin 12).
12 TRI0- input Dedicated transimpedance amplifier (TIA0) negative input, unique to the TSSOP-16 package to provide low-leakage (5 pA typical) performance separate from any GPIO function; this is a high-impedance input and should be left open if unused.
13 P1.5/UCA0CLK/TMS/TRI0O/A5 bidirectional General-purpose digital I/O P1.5 (shared with JTAG; TI recommends disabling the pin interrupt during JTAG debug); alternate functions are eUSCI_A0 SPI clock I/O (UCA0CLK), JTAG test-mode select (TMS), TIA0 output (TRI0O), and ADC analog input A5.
14 P1.4/UCA0STE/TCK/OA0+/A4 bidirectional General-purpose digital I/O P1.4 (shared with JTAG; TI recommends disabling the pin interrupt during JTAG debug); alternate functions are eUSCI_A0 SPI slave transmit enable (UCA0STE), JTAG test clock input (TCK), SAC0 operational-amplifier positive input (OA0+), and ADC analog input A4.
15 P1.3/UCB0SOMI/UCB0SCL/OA0O/A3 bidirectional General-purpose digital I/O P1.3; alternate functions are eUSCI_B0 SPI slave-out data (UCB0SOMI) or I2C clock (UCB0SCL), SAC0 operational-amplifier output (OA0O), and ADC analog input A3.
16 P1.2/UCB0SIMO/UCB0SDA/TB0TRG/OA0-/A2/Veref- bidirectional General-purpose digital I/O P1.2; alternate functions are eUSCI_B0 SPI master-out data (UCB0SIMO) or I2C data (UCB0SDA), Timer0_B3 external high-impedance trigger input (TB0TRG), SAC0 operational-amplifier negative input (OA0-), ADC analog input A2, and ADC negative external reference input Veref-.
