Product details
Overview
MSP430F147IPM from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 32KB flash, 1KB RAM, dual USARTs, a 12-bit ADC with 8 channels and internal reference, two 16-bit timers (Timer_A3 and Timer_B7), and 48 general-purpose I/O pins in a 64-pin LQFP package. It targets battery-powered sensor systems and portable measurement devices requiring sub-6-µs wake-up and <0.1 µA off-mode current.
For engineers reviewing the MSP430F147IPM datasheet, MSP430F147IPM pinout, MSP430F147IPM application, or MSP430F147IPM equivalent, this page delivers verified specifications, validated pin functions, confirmed use cases in industrial sensing and handheld meters, and two technically documented alternative parts for design flexibility.
Technical Context
The MSP430F147IPM implements a 16-bit CPU with constant generators and hardware multiplier, enabling high code efficiency in ultra-low-power operation. Its five power-saving modes-including LPM3 with <6 µs wake-up-are optimized for extended battery life in intermittent-sensing applications.
It integrates two independent 16-bit timers: Timer_A3 with three capture/compare registers supporting PWM and input capture, and Timer_B7 with seven capture/compare registers plus shadow registers for synchronized multi-channel timing control. Both timers support clock sources including ACLK, SMCLK, and external TBCLK.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 125-ns instruction cycle and hardware multiplier for efficient math-intensive firmware. |

FAQ
What is the maximum operating frequency of the MSP430F147IPM?
The MSP430F147IPM operates up to 8 MHz using its digitally controlled oscillator (DCO) with calibration, or up to 8 MHz with external crystal (XT2). Its 125-ns instruction cycle corresponds to an effective 8-MHz CPU clock, enabling responsive real-time control without compromising ultra-low-power operation.
Does the MSP430F147IPM support in-system programming without external voltage?
Yes, the MSP430F147IPM supports serial onboard programming (BSL) with no external programming voltage required. The built-in bootloader enables firmware updates via UART or SPI using only the standard 1.8–3.6 V supply, simplifying field upgrades and eliminating dedicated programming hardware.
How many analog input channels does the MSP430F147IPM ADC support?
The MSP430F147IPM integrates a 12-bit ADC12 module supporting exactly 8 analog input channels (A0–A7), mapped to P6.0 through P6.7. These inputs accept single-ended or differential configurations and support autoscan mode for unattended sequential conversion of all enabled channels.
Is the MSP430F147IPM pin-compatible with other MSP430F14x devices?
Yes, the MSP430F147IPM is fully pin-compatible with MSP430F148IPM and MSP430F149IPM in the 64-pin LQFP (PM) package. All share identical pin numbering, signal assignments, power domains, and peripheral mappings-enabling direct substitution in existing PCB layouts.
What are the key low-power modes supported by the MSP430F147IPM?
The MSP430F147IPM supports five power modes: Active (280 µA @ 1 MHz), LPM0–LPM3 (1.6 µA to 0.1 µA), and LPM4 (0.1 µA with RAM retention). LPM3 retains RAM and register contents while disabling CPU and MCLK, with wake-up in under 6 µs via RTC, GPIO, or timer interrupt-ideal for duty-cycled sensing.
