High-Precision ADC Mixed-Signal Microcontroller

The MAXQ3120 Microcontroller is a high-performance, 16-bit Microcontroller that incorporates dual, true-differen- tial, 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 elec- tricity metering market, but CAN be used in any applica- tion 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 synchro- nous/asynchronous receiver/transmitters (USARTs). The Microcontroller core and I/O are powered by a single 3.3V supply, and an additional battery supply keeps the RTC running during power outages. By Maxim Integrated Products
