Product details
Overview
MSP430F167IRTDR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller with 32KB Flash, 1KB RAM, dual 12-bit DACs, 12-bit ADC with autoscan, two USARTs (UART/SPI/I²C), Timer_A3/Timer_B7, DMA, and integrated comparator - designed for battery-powered sensor nodes and portable instrumentation requiring sub-μA standby current and <6 μs wake-up.
For engineers reviewing the MSP430F167IRTDR datasheet, MSP430F167IRTDR pinout, MSP430F167IRTDR application, or MSP430F167IRTDR equivalent, key selection factors include its 64-pin QFN (RTD) package, dual USART support, 7-channel Timer_B capture/compare capability, 1.8–3.6 V supply range, and flash-based in-system programmability without external voltage.
Technical Context
The MSP430F167IRTDR implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its clock system includes digitally controlled oscillator (DCO), ACLK, SMCLK, and MCLK with XT1/XT2 crystal support.
It integrates two independent serial interfaces: USART0 supports UART, SPI, and I²C modes; USART1 supports UART and SPI only. Timer_B7 provides seven capture/compare registers with shadow registers, while Timer_A3 offers three, both supporting PWM, input capture, and interval timing with interrupt-driven operation.

FAQ
What is the maximum operating frequency of the MSP430F167IRTDR?
The MSP430F167IRTDR supports a maximum CPU clock frequency of 8 MHz via its digitally controlled oscillator (DCO), with typical operation at 1 MHz for optimal power efficiency. The DCO can be calibrated to achieve stable frequencies across voltage and temperature, and external crystals (XT1/XT2) provide higher-precision timing for communication or measurement tasks.
Does the MSP430F167IRTDR support I²C communication?
Yes, the MSP430F167IRTDR supports I²C communication exclusively through USART0, which can be configured in I²C mode using pins P3.1 (SDA) and P3.3 (SCL). USART1 does not support I²C. The hardware includes dedicated I²C interrupt flags and control bits, enabling robust slave or master operation without bit-banging overhead.
How many capture/compare registers does Timer_B have on the MSP430F167IRTDR?
The MSP430F167IRTDR features Timer_B7 with seven capture/compare registers (TBCCR0–TBCCR6), all supported by shadow registers for glitch-free PWM updates. This configuration enables complex waveform generation, multi-phase motor control, or simultaneous timing of up to seven independent events - a key differentiator from the 3-register Timer_B3 in earlier MSP430F15x devices.
Can the MSP430F167IRTDR perform in-system programming without external hardware?
Yes, the MSP430F167IRTDR includes an on-chip bootstrap loader (BSL) that enables in-system programming via UART using only the RST/NMI, TCK, and standard I/O pins (P1.1 for TX, P2.2 for RX). No external programming voltage or JTAG debugger is required - firmware updates can be delivered over existing serial links with password-protected access.
What is the function of the P5.7/TBOUTH/SVSOUT pin on the MSP430F167IRTDR?
On the MSP430F167IRTDR, P5.7 serves dual functions: as TBOUTH (Timer_B output high-impedance control) to simultaneously place all Timer_B PWM outputs in high-Z state, and as SVSOUT (supply voltage supervisor output) to signal brownout or threshold violation. This pin enables safe shutdown sequencing and fault-safe analog output disabling during power anomalies.
