Description and Introduction

16-bit Ultra-Low-Power Microcontroller, 4kB Flash, 256B RAM, Comparator 20-SOIC -40 to 105 # Introduction to the MSP430F2121TDWR Microcontroller  

The MSP430F2121TDWR is a low-power, high-performance 16-bit microcontroller from Texas Instruments' MSP430 family. Designed for energy-efficient embedded applications, this MCU combines ultra-low power consumption with robust processing capabilities, making it ideal for battery-operated devices, sensor nodes, and portable electronics.  

Featuring a 16-bit RISC CPU, the MSP430F2121TDWR operates at up to 16 MHz, delivering efficient performance for real-time control and data processing tasks. It includes 4KB of flash memory and 256B of RAM, providing sufficient storage for small to medium-sized firmware applications. Integrated peripherals such as a 10-bit ADC, timers, and UART/USI communication interfaces enhance its versatility in various embedded designs.  

One of the standout features of this microcontroller is its ultra-low-power architecture, supporting multiple power-saving modes that extend battery life in energy-sensitive applications. The device also includes an on-chip comparator and a watchdog timer, further reducing the need for external components.  

Housed in a compact TSSOP-20 package, the MSP430F2121TDWR is well-suited for space-constrained designs. Its combination of low power consumption, integrated peripherals, and reliable performance makes it a preferred choice for developers working on industrial, medical, and consumer electronics applications.  

With its balance of efficiency and functionality, the MSP430F2121TDWR continues to be a dependable solution for embedded systems requiring both performance and energy optimization.

Application Scenarios & Design Considerations

16-bit Ultra-Low-Power Microcontroller, 4kB Flash, 256B RAM, Comparator 20-SOIC -40 to 105

Alternative Part Number

  • MSP430G2231IPW14 --: Value Line MSP430 in the same 14-pin TSSOP package with comparable Flash/RAM and peripherals; pin-compatible enough for many designs and widely available.
  • MSP430F2131IDW --: Same MSP430F2xx family with similar 16-bit MCU core and 8KB Flash, offered in the same SOIC-20 wide-body footprint as the original DWR package.
  • MSP430F2111IDW --: Lower-density sibling in the same F2xx series and package, suitable when less Flash is acceptable and a drop-in family substitute is needed.
