US electronics giant Texas Instruments (TI) has released a new ultra-low power micro-controller (MCU) for use in smart meters, industrial and remote sensors, home automation and data acquisition systems, the Dallas-based company confirmed this week.

The FRAM MSP430 MCUs can also be used for Internet of Things development and other applications that require flexible memory options and smart analogue integration.

Using ultra-low-leakage technology, the new MCU claims to deliver the world’s lowest system power with active power of 100 uA/MHz, accurate-RTC standby power of 450 nA and performance across temperature range from  -40 to 85 degrees Celsius.

TI’s new products also include a variety of smart analogue peripherals, such as a differential input analogue-to-digital converter that consumes as little as 140 uA 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 accelerator reduce power consumption, bill of materials and board space.

Analyse power consumption

TI’s new EnergyTrace++ technology is a debug system that enables developers to analyse power consumption down to 5nA resolution in real-time for each peripheral, allowing them to control their power budget and optimise software to create low-energy products.

MSP430FR59x MCUs are available 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.
