Microchip Technology PIC18F86J72 & PIC18F87J72 High-Performance MCUs
Microchip Technology PIC18F86J72 and PIC18F87J72 High-Performance Microcontrollers (MCUs) are 8-bit devices for single-phase, multi-function smart metering and energy monitoring applications. The PIC18F86J72 and PIC18F87J72 MCUs feature a dual-channel, high-performance 16- / 24-bit Analog Front End (AFE), making these devices an accurate, reliable, easy-to-use and cost-effective solution for developing meters that exceed IEC class 0.5 performance. This Microchip Technology MCU family includes 64KB or 128KB Flash program memory and 4KB RAM to enable time-of-use and multi-tariff functions. PIC18F86J72 and PIC18F87J72 MCUs provide a high level of peripheral integration, including an LCD driver, RTCC, and Charge-Time Measurement Unit (CTMU) that enables a capacitive-touch user interface.
