Description and Introduction

16-bit Ultra-Low-Power Microcontroller, 2kB Flash, 128B RAM, Comparator 20-SOIC -40 to 85 # Introduction to the MSP430F2111IDWR Microcontroller  

The MSP430F2111IDWR is a low-power, high-performance 16-bit microcontroller from Texas Instruments’ MSP430 family. Designed for energy-efficient embedded applications, it combines robust processing capabilities with ultra-low power consumption, making it ideal for battery-operated devices, sensor nodes, and portable electronics.  

This microcontroller features a 16-bit RISC CPU, 2KB of flash memory, and 128 bytes of RAM, providing sufficient resources for small-scale embedded projects. Its integrated 10-bit ADC (Analog-to-Digital Converter) enables precise analog signal processing, while multiple communication interfaces, including UART and SPI, facilitate seamless connectivity with peripherals.  

A key advantage of the MSP430F2111IDWR is its ultra-low-power operation, supporting multiple power modes to optimize energy usage. With an active mode current consumption as low as 230 µA/MHz and standby currents in the nanoampere range, it extends battery life significantly.  

Housed in a compact TSSOP-20 package, the MSP430F2111IDWR is suitable for space-constrained designs. Its wide operating voltage range (1.8V to 3.6V) enhances flexibility in various power environments. Additionally, built-in security features and a watchdog timer improve system reliability.  

Common applications include medical devices, industrial sensors, and IoT edge nodes where efficiency and reliability are critical. Developers benefit from extensive software support, including TI’s MSP430 development tools and libraries, streamlining firmware development.  

In summary, the MSP430F2111IDWR offers a balanced combination of performance, power efficiency, and integration, making it a versatile choice for embedded systems requiring long-term operation on minimal power.

Application Scenarios & Design Considerations

16-bit Ultra-Low-Power Microcontroller, 2kB Flash, 128B RAM, Comparator 20-SOIC -40 to 85

Alternative Part Number

  • MSP430G2231IPW14 --: Value Line MSP430 in the same family with similar 16-bit MCU features, low power, and comparable peripherals; different series naming makes it easy to distinguish.
  • PIC16F1824-I/SL --: 8/16-bit class low-power MCU with comparable I/O and peripherals from a different vendor and series, suitable as a functional cross-reference.
  • STM8S003F3P6 --: Low-cost 8-bit MCU with similar low-power and general-purpose features, offering a clearly different naming and series as an alternative option.
  • MSP430F2131IDWR --: Same MSP430F2xx family, same 20-pin SOIC wide package and pinout, with larger flash memory, making it a drop-in upgrade for most designs.
  • MSP430G2231IPW20 --: Value-line MSP430 with comparable low-power 16-bit core and peripherals, available in 20-pin TSSOP; requires footprint change but is a cost-effective functional substitute.
