Product details
Overview
MSP430F167IRTDT 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. It operates from 1.8 V to 3.6 V and supports sub-6 μs wake-up from standby mode - ideal for battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F167IRTDT datasheet, MSP430F167IRTDT pinout, MSP430F167IRTDT application, or MSP430F167IRTDT equivalent, key selection criteria include its 64-pin QFN (RTD) package, dual USART support (including I²C on USART0), 7-channel Timer_B capture/compare capability, 32KB Flash memory size, and -40°C to +85°C industrial temperature range.
Technical Context
The MSP430F167IRTDT 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 DCO, ACLK, SMCLK, and MCLK with support for external crystals (XT1/XT2) and internal resistor-controlled frequency tuning via P2.5/Rosc.
It integrates two independent serial interfaces: USART0 supports UART, SPI, and I²C modes; USART1 supports UART and SPI only. The peripheral set includes three-channel DMA, hardware multiplier (MPY/MPYS), and SVS with programmable voltage detection - all optimized for deterministic real-time control in energy-constrained systems.
