Texas Instruments has announced the MSP430AFE2xx series of metrology analogue front end (AFE) 16-bit microcontrollers.

The microcontrollers are designed to offer system partitioning in metering applications, such as electricity meters and home automation.

The 12MHz microcontroller achieves less than 0.1% error in energy accuracy over a dynamic range of 2400:1, using its three 24-bit sigma-delta converters.
 
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. 
 
The MSP430AFE2xx microcontrollers are priced from $0.80 for 1K units and are immediately available. The MSP-TS430PW24 stand alone target board is priced at $75 and can be ordered at www.ti.com/430afe-pr-es.

The MSP-FET430U24 flash emulation tool including software and target board is priced at $149 and can be ordered at www.ti.com/430afe-fet-pr-es.

The MSP430 Energy Watchdog demo and MSP430AFE EVM are available in limited quantities. Please contact local sales representative for additional details.
