Texas Instruments expands world’s lowest power microcontroller portfolio to take your metering, health and fitness and wearables designs to the next level

DALLAS (August 28, 2014) – Enabling developers to reduce power consumption, bill of materials and product size, Texas Instruments (TI) (NASDAQ: TXN) today 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. 

Leveraging MSP430FR69x FRAM MCUs for the smart grid

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 GUIeases 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) oroptical sensors include complete block diagrams, user guides, bill of materials (BOM), design files and test reports. 

Features and benefits of TI’s ultra-low-power MSP430FR69x MCUs:

  • Ease development with pin-to-pin compatibility and a scalable portfolio from 64 KB to 128 KB FRAM and more features within TI’s FRAM MCU platform.
  • Experience the security advantages, including a 256-bit AES accelerator and an IP encapsulation module to protect data transmissions and IP, on MSP430FR69x MCUs. Fast write speeds and low peak currents provide security advantages for generating new security keys and the saving state information in the event of power loss.
  • Break down the barriers associated with traditional MCU memory technologies with FRAM’s unbeatable write energy, write speed, endurance and flexibility.

Pricing and availability

MSP430FR69x MCUs are immediately available in production quantities for USD $4.50 in 1K units. Start designing with the design kitMSP-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.

Add Authentication Security to Automotive Endpoints Using the 1-Wire Interface

Sponsored by Analog Devices

By adding a single authentication IC, automotive designers can authenticate a component with only one signal between an ECU and endpoint component. This is particularly important as counterfeit and theft are increasingly problems in automotive applications. This application note describes how to implement the DS28E40 Deep Cover 1-Wire Authenticator in a system to provide authentication for optical cameras, headlamps, EV Batteries, occupancy sensors, and even steering wheels, and more.
