MAXIM INTEGRATED PRODUCTS 78M6612-IGT/F 芯片, 特殊功能
The is a single phase, dual outlet power and energy measurement IC in 64 pin LQFP package. This monitoring system-on-chip SoC includes a 32bit compute engine CE, an MPU core, RTC and flash. This Single Converter Technology with a 22bit delta sigma ADC, 4 analogue inputs, digital temperature compensation & precision voltage reference supports a wide range of single phase, dual outlet power measurement applications with very few external components. With measurement technology leveraged from Maxim"s flagship utility metering ICs, device offers features including 32KB of flash program memory, 2KB shared RAM, 3 low power modes with internal timer or external event wake-up, 2 UARTs, I2C/MICROWIRE EEPROM I/F and an in-system programmable flash. Complete outlet measurement unit OMU and AC power monitor AC-PMON firmware is available or can be preloaded into IC. It is used in communication & computer power supplies, consumer white goods, home and commercial automat
