MSP430F149IRTDT Technical Specifications

MSP430F149IRTDT Key Features

• One 16?bit core delivers efficient integer and control processing with lower code size versus 32?bit alternatives.
• On?chip nonvolatile memory in the tens of kilobytes reduces external Flash, lowering board cost and improving reliability.
• Integrated analog and digital peripherals, including a 12?bit ADC and multiple timers, cuts BOM and simplifies signal chain design.
• Industrial temperature rating and a 64?pin package enable deployment in harsh environments and dense I/O?rich applications.

Typical Applications

• Industrial sensor nodes requiring low active power, reliable operation from -40 ??C to +85 ??C, and local ADC sampling to minimize external components.
• Battery?powered meters and portable instruments that need tens of kilobytes of on?chip code storage and a 16?bit arithmetic unit for signal processing.
• Motor control and power conversion monitoring where multiple 16?bit timers and precise ADC conversions provide deterministic control loops.
• Legacy and new embedded control platforms that require serial connectivity (UART/SPI/I2C) and robust, low?power operation in production appliances.

MSP430F149IRTDT Advantages vs Typical Alternatives

The MSP430F149IRTDT combines a 16?bit low?power core with integrated analog and serial peripherals to offer a smaller BOM and lower operating current than many 8? or 32?bit solutions for similar control tasks. Compared to microcontrollers with external memory needs, it provides tens of kilobytes of on?chip flash and kilobytes of RAM to store firmware and data locally. Its industrial temperature range and 64?pin package make it more suitable for harsh or I/O?dense applications where cost and energy per operation matter.
