It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and portable instrumentation.
For engineers reviewing the MSP430F167IPMR datasheet, MSP430F167IPMR pinout, MSP430F167IPMR application, or MSP430F167IPMR equivalent, key selection criteria include its 64-pin QFP package, LPM4 standby current of 0.2 μA, 6 μs wake-up time, dual USART support, and integrated analog peripherals for closed-loop control and data acquisition.
Technical Context
The MSP430F167IPMR 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 and XT2 crystal oscillator inputs supporting precise timing.
It integrates two independent serial interfaces-USART0 (UART/SPI/I²C) and USART1 (UART/SPI)-with dedicated pins for STE, SIMO, SOMI, UCLK, URXD, and UTXD on Ports P3–P5. Timer_B7 provides seven capture/compare registers with shadow registers for glitch-free PWM generation in motor control or power conversion.

FAQ
What is the maximum operating frequency of the MSP430F167IPMR?
The MSP430F167IPMR supports a maximum CPU clock frequency of 8 MHz via its digitally controlled oscillator (DCO), with stable operation up to 1 MHz typical in active mode at 2.2 V. The DCO can be calibrated to achieve ±3% accuracy across voltage and temperature, and external crystals (XT1/XT2) support precise timing up to 8 MHz. This frequency headroom enables real-time signal processing in applications like ultrasonic flow measurement or digital filtering without external clock sources.
Does the MSP430F167IPMR support I²C communication?
Yes, the MSP430F167IPMR 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 and is limited to UART and SPI protocols. The I²C implementation complies with standard mode (100 kbps) and fast mode (400 kbps) specifications, with built-in start/stop detection and address recognition - enabling direct interfacing with common I²C sensors and EEPROMs without external level shifters.
How many I/O pins does the MSP430F167IPMR have, and what is their voltage tolerance?
The MSP430F167IPMR provides 48 general-purpose I/O pins across Ports P1–P6, all configurable as digital inputs/outputs with interrupt capability. These pins operate at the core supply voltage (DVCC = 1.8–3.6 V) and are not 5V-tolerant. Analog-capable pins (P6.0–P6.7) support 12-bit ADC inputs and DAC outputs, while dedicated peripheral pins (e.g., TCK, TMS, URXD0) retain dual functionality. All I/Os include programmable pull-up/down resistors and edge-selectable interrupts for robust button sensing or wake-up signaling.
What development tools are compatible with the MSP430F167IPMR?
The MSP430F167IPMR is fully supported by Texas Instruments' MSP-FET430UIF (USB JTAG emulator), MSP-TS430PM64 (target board for 64-pin QFP), and Code Composer Studio IDE. It also works with open-source tools like naken_asm and mspdebug via Spy-Bi-Wire or JTAG. The onboard Embedded Emulation Module (EEM) enables real-time debugging, flash programming, and breakpoint execution - critical for validating low-power modes and peripheral timing in battery-constrained designs.
Is the MSP430F167IPMR RoHS compliant and qualified for industrial temperature range?
Yes, the MSP430F167IPMR is RoHS compliant and rated for operation from −40°C to +85°C, meeting industrial-grade reliability standards. Its qualification includes HTOL (high-temperature operating life), ESD (±2 kV HBM), and latch-up immunity per JEDEC JESD78. The PM package uses lead-free matte tin plating and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3, ensuring robustness in automated SMT assembly and harsh environmental deployments.
