MCUs for energy metering
21 March 2012, DSP, Micros & Memory
Offering developers more flexibility in electricity metering and energy monitoring applications, Texas Instruments has rolled out the MSP430F673x/F672x family of low-power 16-bit microcontrollers.
The new devices guarantee no interruption of operation through a backup capable microcontroller supporting real-time clock (RTC) operation and power management from the main power supply and up to two separate auxiliary supplies. The 24 new devices also achieve more precise measurements through an increased sampling rate and superior linearity over multiple operating conditions, such as current range and time, resulting in a stable system solution.
These devices are TI’s first 6xx series microcontrollers with integrated 24-bit sigma-deltas and a 320-segment LCD controller. As part of the MSP430 microcontroller portfolio, the F673x/F672x devices are designed for ultra-low-power modes, ensuring the LCD display is consuming as little power as possible during operation.
The devices’ powerful 24-bit sigma-delta with programmable gain amplifier and less than 0,1% accuracy across a 2400:1 dynamic range enables the F673x/F672x family to meet Class 0.1 meters and exceed IEC62053/ANSI C12.20. The sigma-delta converter offers independent channels for voltage, current and tamper detection, reducing energy measurement software development and security concerns.
The 320-segment LCD driver enables segment and blinking control and dual display memory, and can also run in 8-MUX mode to support multiple LCD devices. The MCUs offer power consumption of 1,4 μA in standby mode with fast wake-up at less than 3 μs.
TI’s free MSP430 Energy Library is available to support metrology software on the new devices, providing an easy startup for customers developing a utility meter product. Developers can test and experience accuracy results with the MSP430F6736 EVM, a single-phase electricity meter, as well as program and debug F673x/F672x devices with the MSP-TS430PZ100B target board and MSP-FET430U100B Flash emulation tool. |
