MCUs' smart analogue enables measurement accuracy

Providing accuracy and precision down to 1% in smart metering products across a 2000:1 dynamic range, the MCUs feature integrated smart analogue, including up to four integrated sigma-delta ADCs. The need for an external crystal is also removed by an internal DCO. The MSP430i204x series of MCUs are suitable for occupancy sensors, remote temperature and pressure transmitters and power monitoring.

The MSP430i204x industrial MCUs allow developers to scale their designs to include 16 or 32KB flash memory and integrated analogue such as sigma-delta AFEs. To help developers start their embedded server power metering and smart power strip designs, TI offers three comprehensive reference designs with schematics, block diagrams, BOM, design files and test reports.

To enable industrial designs to communicate with other connected devices, developers can use the company's SimpleLink WiFi CC3200 wireless MCU. TI's DAC8760 family of DACs for 4-20mA current loop industrial sensor applications can also be used to further reduce board space and lower system costs, while maintaining high accuracy in their designs.

Offered in 28-pin TSSOP and 32-pin QFP, the devices enable designers to reduce board space and lower system costs, while increasing accuracy. The MSP430i2040 MCUs with 16KB priced at $1.70 each in 1,000 unit quantities, while the MSP430i2041 MCUs with 32KB are priced at $1.75 each in 1,000 unit quantities.
