Rev 1; 8/05 High-Precision ADC Mixed-Signal Microcontroller General Description The MAXQ3120 microcontroller is a high-performance, 16-bit microcontroller that incorporates dual, true-differential, 16-bit sigma-delta analog-to-digital converters (ADCs), a liquid-crystal display (LCD) interface that can drive up to 112 segments, and a real-time clock (RTC) module with a dedicated battery-backup supply. The MAXQ3120 is uniquely suited for the single-phase electricity metering market, but can be used in any application that requires high-performance operation. The device can operate at a maximum of 8MHz (DVDD = 3.3V). The MAXQ3120 has 16kWords of flash memory, 256 words of RAM, three 16-bit timers, and two universal synchronous/asynchronous receiver/transmitters (USARTs).
