Product details
Overview
MSP430F169IPM from Texas Instruments is an ultralow-power 16-bit RISC mixed-signal microcontroller with 60KB+256B flash memory, 2KB RAM, dual 12-bit DACs, 12-bit ADC with autoscan, two USARTs (UART/SPI/I²C), and seven-capture/compare Timer_B. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F169IPM datasheet, MSP430F169IPM pinout, MSP430F169IPM application, or MSP430F169IPM equivalent, key selection considerations include its 64-pin QFP package, 7-channel Timer_B, dual USART support, 60KB flash capacity, and LPM4 standby current of 0.2 μA with RAM retention.
Technical Context
The MSP430F169IPM implements a 16-bit CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its architecture integrates three-channel DMA, hardware multiplier (MPY/MAC), and programmable clock system with DCO, ACLK, SMCLK, and MCLK domains.
It features two independent USART modules: USART0 supports UART, SPI, and I²C; USART1 supports UART and SPI only. The 12-bit ADC includes internal reference, sample-and-hold, and autoscan across eight analog inputs, while dual 12-bit DACs provide synchronized voltage outputs on P6.6 and P6.7.

FAQ
What is the maximum operating frequency of the MSP430F169IPM?
The MSP430F169IPM supports a maximum CPU clock frequency of 8 MHz via its digitally controlled oscillator (DCO), with instruction cycle time of 125 ns. External crystals up to 8 MHz can be used with XT1 (watch crystal) or XT2 (standard crystal) oscillators, and the DCO can be calibrated to maintain timing accuracy across voltage and temperature variations.
Does the MSP430F169IPM support I²C communication?
Yes, the MSP430F169IPM supports I²C communication exclusively through USART0, which functions as an I²C master or slave interface on pins P3.1 (SDA) and P3.3 (SCL). USART1 does not support I²C mode and is limited to UART and SPI protocols per the device specification.
How many analog input channels does the MSP430F169IPM ADC support?
The MSP430F169IPM integrates a 12-bit ADC12 module with eight selectable analog input channels (A0–A7), accessible via P6.0 through P6.7. The autoscan feature allows automatic sequential conversion across all enabled channels without CPU intervention, reducing firmware overhead in multi-sensor systems.
What debug and programming interfaces are available on the MSP430F169IPM?
The MSP430F169IPM provides JTAG (TCK, TMS, TDI/TCLK, TDO/TDI) for full-speed emulation and flash programming, plus a UART-based bootstrap loader (BSL) accessible via P1.1 (TX) and P2.2 (RX). Both interfaces support secure code protection via fuse-based security lock and password-protected BSL access.
Is the MSP430F169IPM pin-compatible with other devices in the MSP430F16x family?
Yes, the MSP430F169IPM shares identical 64-pin QFP (PM) packaging and pin mapping with MSP430F167IPM and MSP430F168IPM, including functionally matched I/O, timer, ADC, and communication pins. This enables direct PCB-level substitution where flash and RAM requirements align with the target variant.
