Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced the 8-bit PIC18F87J72 microcontroller (MCU) family for single-phase, multi-function smart-metering and energy-monitoring applications. Featuring a dual-channel, high-performance 16-/24-bit Analog Front End (AFE), the new MCUs provide an accurate, reliable, easy-to-use and cost-effective solution for developing meters that exceed International Electrotechnical Commission (IEC) class 0.5 performance. The family includes 64 or 128 KB Flash program memory and 4 KB RAM, to enable time-of-use and multi-tariff functions; as well as a high level of peripheral integration, including a LCD driver, hardware Real-Time Clock/Calendar (RTCC) and a Charge-Time Measurement Unit (CTMU) that enables a capacitive-touch user interface.
“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.”
