Overview
MSP430F167IPM from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 32KB+256B flash memory, 1KB RAM, dual 12-bit DACs, a 12-bit ADC with internal reference and autoscan, two USARTs (UART/SPI/I²C), three-channel DMA, and Timer_B with seven capture/compare registers - deployed in portable sensor systems and battery-powered industrial meters.
For engineers reviewing the MSP430F167IPM datasheet, MSP430F167IPM pinout, MSP430F167IPM application, or MSP430F167IPM equivalent, key selection criteria include its 64-pin QFP package, −40°C to 85°C operating range, dual USART support, 1.8–3.6 V supply, and LPM4 standby current of 0.2 μA with RAM retention.
Technical Context
The MSP430F167IPM 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 integrates DCO, ACLK, SMCLK, and MCLK with programmable dividers and external crystal support (XT1/XT2).
It features two independent serial interfaces: USART0 supports UART, SPI, and I²C modes; USART1 supports UART and SPI only. Timer_B includes seven capture/compare registers with shadow registers for glitch-free PWM, while Timer_A provides three capture/compare registers and asynchronous event handling.

FAQ
What is the maximum operating frequency of the MSP430F167IPM?
The MSP430F167IPM supports a maximum CPU clock frequency of 8 MHz using the internal DCO or external XT2 oscillator. Its 125-ns instruction cycle time enables deterministic real-time response for time-critical sensor sampling and control loops. The device maintains full functionality across its 1.8–3.6 V supply range at this speed, and the DCO can be calibrated to achieve ±1% accuracy over temperature and voltage.
Does the MSP430F167IPM support I²C communication?
Yes, the MSP430F167IPM supports I²C communication exclusively through USART0, which operates in I²C mode using P3.1 (SDA) and P3.3 (SCL). USART1 does not support I²C. The hardware I²C module includes clock stretching, 7-bit/10-bit addressing, and interrupt-driven transaction handling - eliminating bit-banged software implementations and reducing CPU load during sensor bus communication.
How many analog input channels does the MSP430F167IPM ADC support?
The MSP430F167IPM integrates a 12-bit ADC12 module with eight selectable analog input channels (A0–A7), accessible via P6.0 through P6.7. It supports single-channel, sequence-of-channels, and repeat-sequence conversion modes with autoscan, internal reference (2.5 V), and sample-and-hold - enabling simultaneous multi-sensor acquisition without external multiplexing circuitry.
What development tools are compatible with the MSP430F167IPM?
The MSP430F167IPM is fully supported by TI's MSP-FET430UIF (USB JTAG), MSP-FET430U64 (target board for PM package), and MSP-TS430PM64 (standalone PM socket board). Code development uses MSP430 GCC or TI's Code Generation Tools, with debugging via Embedded Emulation Module (EEM). The device also supports UART-based BSL programming using P1.1 and P2.2 pins for field firmware updates.
Is the MSP430F167IPM pin-compatible with other devices in the MSP430F16x family?
Yes, the MSP430F167IPM is pin-compatible with all 64-pin QFP (PM) variants in the MSP430F16x family, including MSP430F168IPM and MSP430F169IPM.
