The MSP430i20xx has some great analog integrated – it has up to four Sigma delta converters that have better than 1% error in energy accuracy rate. Designers are assured of precise measurements for low and high currents due to the wide dynamic range of 2000:1. The i20xx comes with an internal DCO, eliminating the need for an external crystal. Additionally the small packages, 28-pin TSSOP and 32-pin QFP, help reduce overall system area and cost. These MSP430 devices are functional across a wide range of temperatures from -40oC to 105oC making it suitable for industrial applications. Texas Instruments provides hardware and software tools needed to jumpstart new designs. The first is a simple target board that can be programmed to demonstrate basic functionality. There are also two i2040 EVMs, one for utility metering and the other for sub metering, that are metering reference designs which are complete metrology solutions for evaluation purposes.
