Description and Introduction

16-bit Ultra-Low-Power MCU, 16kB Flash, 512B RAM, 12-Bit ADC, Dual 12-Bit DAC, USART, I2C, DMA 64-VQFN -40 to 85 # Introduction to the MSP430F155IRTDR Microcontroller  

The MSP430F155IRTDR is a low-power, high-performance microcontroller from Texas Instruments’ MSP430 family. Designed for energy-efficient applications, this 16-bit RISC-based MCU combines robust processing capabilities with ultra-low power consumption, making it ideal for battery-operated and portable devices.  

Featuring a 16-bit CPU, the MSP430F155IRTDR operates at up to 16 MHz, delivering efficient processing while minimizing power usage. It includes 16KB of flash memory and 512B of RAM, providing sufficient storage for embedded applications. The device also integrates a 10-bit analog-to-digital converter (ADC), multiple timers, and serial communication interfaces such as UART, SPI, and I2C, enhancing its versatility for various embedded designs.  

One of the key strengths of the MSP430F155IRTDR is its ultra-low-power architecture, supporting multiple power modes to optimize energy consumption. This makes it well-suited for applications like sensor nodes, wearable devices, and IoT solutions where extended battery life is critical.  

The microcontroller comes in a compact 38-pin TSSOP (RTD) package, enabling space-efficient PCB designs. With its blend of performance, low power, and integrated peripherals, the MSP430F155IRTDR is a reliable choice for developers seeking an efficient and scalable embedded solution.  

Whether used in industrial control systems, medical devices, or consumer electronics, this microcontroller offers a balance of functionality and energy efficiency, meeting the demands of modern embedded applications.

Alternative Part Number

  • MSP430F149IPM --: Same MSP430F1xx family with larger flash and RAM, compatible 16-bit RISC core and peripherals; available in LQFP package and widely stocked as a drop-in upgrade for many designs.
  • MSP430F135IPM --: Closely related MSP430F1xx device with similar peripheral set (ADC, timers, USART) and lower cost; suitable when slightly less memory is acceptable.
  • MSP430F1611IPM --: Higher-performance MSP430F1xx variant with more memory and dual USARTs, offering a robust functional replacement when board space and pinout can be adapted.
