TI’s MSP430 MCUs with EnergyTrace++ enable lowest power MCU systems

The ultra-low power FRAM microcontroller (MCU) platform from Texas Instruments includes all the necessary hardware and software tools, and support for developers to reduce energy budgets, minimize product size and enable a battery-free world. TI’s new MSP430FR59x/69x FRAM MCU families with EnergyTrace++ real-time power profiler and debugger range from 32 to 128 KB embedded FRAM. These MSP430 MCUs are ideal for smart utility metering, wearable electronics, industrial and remote sensors, energy harvesting, home automation, data acquisition systems, the Internet of Things (IoT) and many more applications that require ultra-low power consumption, flexible memory options and smart analog integration.

TI claims that its ultra-low-leakage (ULL) proprietary technology with embedded FRAM delivers the world’s lowest system power with active power of 100 µA/MHz, accurate-RTC standby power of 450 nA and industry-leading power performance across temperature range from  -40 to 85 degrees Celsius. The new FRAM MCUs include a variety of smart analog  peripherals, such as a differential input analog-to-digital converter (ADC) that consumes as little as 140 µA at 200 ksps and an enhanced scan interface for flow metering that can operate while the system is in standby, resulting in 10 times lower power. In addition, an integrated 8-mux LCD display and 256-bit Advanced Encryption Standard (AES) accelerator reduce power consumption, bill of materials and board space.

TI’s new EnergyTrace++ technology is the world’s first debug system that enables developers to analyze power consumption down to 5nA resolution in real-time for each peripheral. This allows engineers to take control of their power budget and optimize software to create the lowest energy product possible. This new technology is now available for both MSP430FR59x and MSP430FR69x MCU families and with the new low-cost MSP430FR5969 LaunchPad development kit.

MSP430FR59x MCUs are available immediately in production quantities for $3.35 USD in 1K units. The MSP430FR69x MCUs are available for sampling, with full production quantities available in 3Q 2014.
