Ultra-Low-Power FRAM Microcontrollers

Enabling developers to reduce power consumption, bill of materials and product size, Texas Instruments (TI) released 46 new ultra-low-power MSP430 FRAM microcontrollers (MCUs) with more memory, features and integration. TI's MSP430FR69x MCUs are scalable up to 128 KB non-volatile FRAM memory and include smart analog integration, such as an extended scan interface (ESI) and a differential input analog-to-digital converter (ADC) that consumes as little as 140 µA at 200 KSPS. Developers can also leverage the integrated 320-segment LCD controller to easily add a display to their products and a 256-bit advanced encryption standard (AES) hardware accelerator to increase security of data transmissions. This integration not only reduces overall power consumption, it minimizes product size by eliminating redundant components in systems.

TI's focus on optimizing its MSP430FR69x MCUs for ultra-low-power and high integration yields MCUs with the lowest active, standby and peripheral power in the industry. Unbeatable write speeds of MSP430FR69x FRAM MCUs and 10 billion times more write-erase cycles than flash solutions results in memory that can reduce power, increase data accuracy over time, and even extend product lifetime. FRAM offers unmatched memory flexibility, does not require pre-erasure of segments and can be accessed at the bit-level, enabling constant on-the-fly data logging and faster, simpler wireless firmware updates.

The integrated ESI module, differential ADC and LCD controller make MSP430FR69x MCUs ideal for smart flow metering designs for water, gas and heat. Adding TI's complementary SimpleLink™ Sub-1 GHz CC1120 transceiver, SimpleLink Wi-Fi CC3100 wireless network processor or Wireless M-Bus connectivity solutions can easily connect a new MSP430FR69x-based flow meter design to the grid. Power-conscious developers can also include TI's TPS61220 boost converter to optimize battery-powered systems. TI's new FlowESI GUI eases sensor setup in software and EnergyTrace++™ technology enables developers to debug power consumption at a function- and peripheral-level like never before. These resources help developers optimize their metering designs and speed time-to-market. Get flow metering designs started quicker with three comprehensive TI Designs based on MSP430FR69x MCUs that leverage the integrated extended scan interface module. These complete reference designs for water meters using inductive-capacitive (LC), giant magneto-resistive (GMR) or optical sensors include complete block diagrams, user guides, bill of materials (BOM), design files and test reports.
