Focusing on metering and smart grid applications, Texas Instruments announced the MSP430AFE2xx series of metrology analog front end (AFE) low-power, 16-bit microcontrollers.
The low-cost device family offers programmable single-phase metrology devices supported with multiple communication interfaces. The microcontrollers enable system partitioning in metering applications such as electricity meters, home automation, sub-metering and energy saving systems, which allows flexible, standalone, high-quality measurement. The devices are based on a 16-bit RISC architecture with a system frequency of 12 MHz. They achieve less than 0,1% error in energy accuracy over a wide dynamic range of 2400:1, enabled by three independent 24-bit sigma-delta converters supporting anti-tamper.
The MSP430AFE2xx series is also supported by multiple tools, demos and EVMs to provide several options for developers to begin evaluation and move quickly to production. Allowing users to manage energy usage and begin saving money, the RF-capable MSP430 Energy Watchdog demo displays the electricity consumption of any plug-in appliance on an LCD display. The programmable MSP430AFE EVM can be used to test the new MSP430AFE2xx as a calibrated electricity meter. Additionally, the MSP-TS430PW24 target board and MSP-FET430U24 Flash emulation tool can be used to program and debug the MSP430AFE devices.
