Description and Introduction

16-Bit Ultra-Low-Power Microcontroller, 8kB Flash, 256B RAM, Comparator 24-VQFN -40 to 85 # Introduction to the MSP430F2131IRGER Microcontroller  

The MSP430F2131IRGER is a low-power, high-performance microcontroller from Texas Instruments’ MSP430 family. Designed for embedded applications requiring efficient power consumption and robust processing capabilities, this 16-bit MCU is ideal for battery-operated devices, sensor interfaces, and portable instrumentation.  

Featuring a RISC-based CPU with a clock speed of up to 16 MHz, the MSP430F2131IRGER delivers responsive performance while maintaining ultra-low power consumption. Its integrated peripherals include a 10-bit ADC, timers, UART, and I²C/SPI communication interfaces, making it versatile for various embedded designs.  

The device operates within a supply voltage range of 1.8V to 3.6V, supporting energy-efficient operation modes such as standby and active-low power states. With 8KB of flash memory and 512B of RAM, it provides sufficient storage for firmware and data processing in constrained environments.  

Packaged in a compact 24-pin VQFN (RGE) form factor, the MSP430F2131IRGER is well-suited for space-constrained applications. Its robust architecture and extensive development support, including TI’s MSP430 toolchain, facilitate rapid prototyping and deployment.  

Engineers favor this microcontroller for its balance of performance, power efficiency, and integration, making it a reliable choice for industrial, medical, and consumer electronics applications. Whether used in wireless sensor nodes, handheld devices, or control systems, the MSP430F2131IRGER offers a cost-effective and scalable solution.

Application Scenarios & Design Considerations

16-Bit Ultra-Low-Power Microcontroller, 8kB Flash, 256B RAM, Comparator 24-VQFN -40 to 85

Alternative Part Number

  • MSP430G2231IRHB --: Same MSP430 family, similar 16-bit MCU with comparable peripherals and low power, different package and value line series for easy drop-in redesign.
  • STM8S003F3P6 --: Pin-compatible 8-bit MCU alternative with similar GPIO, timers, and low-power operation, suitable when firmware porting is acceptable.
  • PIC16F1824-I/SL --: Comparable low-power 8-bit MCU with integrated ADC and timers, widely available alternative for cost-sensitive designs requiring similar functionality.
  • MSP430F2132IRHBR --: Same MSP430F2xx family with similar Flash/RAM and peripherals, available in a 32-pin QFN package; verify pinout and memory size before use.
  • MSP430G2553IRHB32 --: Value-line MSP430 in a 32-pin QFN with comparable low-power operation and integrated peripherals; a practical substitute when slight memory differences are acceptable.
  • MSP430F2122IRHBR --: Closely related MSP430F2xx device in QFN packaging with similar core and analog features; check Flash size and pin mapping for the target design.
