Microchip unveils mcus for smart metering applications
1 min read
Microchip Technology has launched an 8bit microcontroller range for single-phase, multi-function smart metering and energy monitoring applications.
Featuring a dual channel, 16/24bit analogue front end, the PIC18F87J72 mcus are designed to provide a solution for developing meters that exceed International Electrotechnical Commission (IEC) class 0.5 performance.
The range includes 64 or 128Kb Flash program memory and 4Kb RAM, as well as an integrated lcd driver, hardware real time clock/calendar and a charge - time measurement unit that enables a capacitive-touch user interface. Energy calculation firmware, a development board and a reference design are available.
"The PIC18F87J72 mcu family addresses market demands for an integrated smart energy metering and power monitoring mcu," said Mitchel Obolsky, vice president of Microchip's Advanced Microcontroller Architecture Division. "These new mcus expand Microchip's existing energy metering and power monitoring portfolio. Customers now have the option of selecting the PIC18F87J72 mcu with AFE for small size, or a separate Microchip MCP390X AFE with a standard PIC mcu for maximum flexibility."
The mcus are available in an 80pin 12 x 12 x 1mm TQFP package.
