Description and Introduction

16-Bit Ultra-Low-Power Microcontroller, 8kB Flash, 256B RAM, USART, Comparator # Introduction to the MSP430F123IPWR Microcontroller  

The MSP430F123IPWR is a low-power, high-performance 16-bit microcontroller from Texas Instruments’ MSP430 family. Designed for embedded applications requiring efficient power consumption and robust processing capabilities, this microcontroller is well-suited for battery-operated devices, sensor interfaces, and portable instrumentation.  

Featuring a 16-bit RISC CPU, the MSP430F123IPWR operates at up to 8 MHz, delivering fast execution while maintaining ultra-low power consumption. Its advanced architecture supports multiple low-power modes, making it ideal for energy-sensitive applications. The device includes 8KB of flash memory and 256B of RAM, providing sufficient storage for embedded firmware and data processing tasks.  

Integrated peripherals enhance its versatility, including a 10-bit analog-to-digital converter (ADC), timers, serial communication interfaces (UART, SPI, I2C), and a watchdog timer for system reliability. The MSP430F123IPWR operates across a wide voltage range (1.8V to 3.6V), further optimizing power efficiency.  

Housed in a compact TSSOP-28 package, this microcontroller is suitable for space-constrained designs. Its robust feature set and low-power operation make it a preferred choice for applications such as industrial control systems, medical devices, and consumer electronics.  

With a strong development ecosystem, including software tools and reference designs, the MSP430F123IPWR simplifies implementation while ensuring performance and reliability in demanding embedded environments.

Application Scenarios & Design Considerations

16-Bit Ultra-Low-Power Microcontroller, 8kB Flash, 256B RAM, USART, Comparator

Alternative Part Number

  • MSP430F1232IPWR --: Same MSP430F1xx family with identical 20-pin TSSOP package and core, adding 2KB flash; drop-in compatible in most designs with minor firmware adjustment.
  • MSP430F1222IPWR --: Pin-compatible MSP430F1xx variant in the same TSSOP-20 package with 4KB flash, suitable when slightly less memory is acceptable.
  • MSP430G2553IPW20 --: Value-line MSP430 in the same 20-pin TSSOP footprint with comparable peripherals; a cost-effective alternative requiring code recompilation.
  • MSP430G2231IPW14 --: Value-line MSP430 in a 14-pin TSSOP with 2KB flash; different pin count requires layout change but provides a modern, low-cost substitute for simple applications.
