SoC MCU solution suits e-metering

15 April 2009 Analogue, Mixed Signal, LSI

Texas Instruments has developed the MSP430FE42x2 microcontroller series to suit the needs of single-phase electricity metering (e-metering) applications. The MCUs integrate metering functionality onto a single system-on-chip (SoC) and offer ultra-low power operation so that only simple voltage regulation is required for a complete solution. They come in a 64-pin LQFP package and offer up to 32 KB of in-system programmable Flash memory. They are fully compatible with the MSP-FET430U64 JTAG emulation toolkit.

A unique embedded signal processor (ESP) peripheral automates energy conversion by integrating two independent, high-resolution sigma-delta ADCs, programmable gain amplifiers, a temperature sensor, precision voltage reference, H/W multiplier and a dedicated fixed-function MSP430 CPU. The ESP provides 0,1% accurate energy measurement over a dynamic current range of 1000-to-1.

A second, fully-programmable on-chip MSP430 CPU is available for application processing and communication functions. An enhanced watchdog timer, brownout protection and a supply voltage supervisor increase system reliability. Also onboard are a 128 segment LCD driver, a three channel 16-bit pulse width modulation timer, serial communication port and a basic timer for a realtime clock function.

The device operates from a 3 V supply with the CPU and ESP active at only 2,5 mA. During a power outage, the device can operate in standby mode at 1,1 μA with the realtime clock function active. The device’s low power consumption is said to enable 10 and 20-year battery life in metering applications.
