TI expands ultra-low-power FRAM MCU portfolio

Texas Instruments (TI) has released 46 new ultra-low-power MSP430 FRAM (ferroelectric RAM) microcontrollers (MCUs) with more memory, features and integration. 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.

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 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 are targeted 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.

MSP430FR69x MCUs are immediately available in production quantities for USD $4.50 in 1K units. Start designing with the design kit MSP-FET430U100D for $175 on TI's eStore or from authorized distributors. The EVM430-FR6989 flow meter evaluation kit will be available in October for $300.
