Hi Sumathi, We offer many TI Designs based on MSP430 for energy metering applications, and based on your application, I've listed a few below for your reference. 1. TIDM-SINGLEPHASEMETER (supports LCD, EVM available for purchase) 2. TIDM-1PHMTR-ESD (similar to the design above, but with enhanced ESD protection) 3. TIDM-SINGLEPHASEMETER-AFE (single chip solution with LCD) 4. TIDM-METROLOGY-HOST (two chip solution with LCD, isolated energy measurement) 5. TIDM-SERVER-PWR-MON (can work in either DC or AC mode, no LCD, could be used with a host microcontroller, see Figure 3 in the User's Guide for how to measure high voltages using resistor ladder, EVM available for purchase) Regards, James MSP Customer Applications
