Texas Instruments MSP430F471xx Microcontrollers for e-Metering
Texas Instruments (TI) introduced the ultra-low power MSP430F471xx microcontroller (MCU) series. The F471xx system-on-chip metering solution features simultaneous sampling of voltage and current as well as tamper-detection for efficient and reliable energy measurement. The MSP430F471xx microcontrollers are ideal for three-phase e-metering applications. The devices are fully compatible with the $149 MSP-FET430U100A flash emulation tool and e-meter EVM. F471xx MCUs are priced between $5.75 and $7.95 for 1K units and are available now along with the $75 MSP-TS430PZ100A target board.
MSP430F471xx Three-phase E-metering MCU Features
- Integrated MCU solution with dedicated 16-bit sigma delta converters for three-phase e-metering applications
- Precise energy measurements with better than 0.1 percent accuracy
- Well suited for power-line monitoring with simultaneous sampling of all channels
- Ultra-low power consumption when LCD, real-time clock and other peripherals are in use helps maintain data when back-up battery is used during power outage
- Support of tamper detection and high-precision measurements like temperature and humidity with 7th sigma delta converter for measurement of current and voltage signals
- Flexible memory options with up to 120kB Flash and 8kB RAM
- Development made easy with code examples, evaluation module and application note that details faster calibration to jump-start design
