Description and Introduction

16-Bit Ultra-Low-Power Microcontroller, 60 kB Flash, 2KB RAM, 2 USARTs, HW multiplier # Introduction to the MSP430F1491IPMG4 Microcontroller  

The MSP430F1491IPMG4 is a versatile, ultra-low-power microcontroller from Texas Instruments' MSP430 family. Designed for embedded applications requiring efficient power consumption and robust performance, this 16-bit RISC-based MCU is ideal for battery-operated devices, sensor nodes, and portable instrumentation.  

Featuring a 16-bit CPU with a wide range of peripherals, the MSP430F1491IPMG4 operates at up to 8 MHz and includes 60KB of flash memory and 2KB of RAM, providing ample storage for embedded firmware. Its integrated analog-to-digital converter (ADC), timers, and serial communication interfaces (UART, SPI, I²C) enhance its flexibility for diverse applications.  

A key advantage of this microcontroller is its ultra-low-power architecture, supporting multiple low-power modes that extend battery life in energy-sensitive designs. The MSP430F1491IPMG4 also includes a hardware multiplier, enabling efficient digital signal processing (DSP) operations.  

Housed in a 64-pin LQFP package, this MCU is well-suited for industrial, medical, and consumer electronics applications where reliability and energy efficiency are critical. Its development ecosystem, supported by TI’s Code Composer Studio and open-source tools, simplifies firmware development and debugging.  

With its balance of performance, power efficiency, and integrated features, the MSP430F1491IPMG4 is a strong choice for developers seeking a cost-effective, low-power microcontroller for embedded systems.

Application Scenarios & Design Considerations

16-Bit Ultra-Low-Power Microcontroller, 60 kB Flash, 2KB RAM, 2 USARTs, HW multiplier

Alternative Part Number

  • MSP430F149IPM --: Same MSP430F1xx family in the same 64-pin LQFP package with comparable Flash and peripherals; drop-in compatible for most designs.
  • MSP430F169IPM --: Higher-integration MSP430F1xx device in the same 64-pin LQFP package, offering more Flash/RAM and dual DACs, suitable when extra features are acceptable.
  • MSP430F5438AIPZ --: Newer MSP430F5xx generation in a 100-pin LQFP with more memory and peripherals; a good upgrade path when board layout can be revised.
