MAXQ3100

www.DataSheet4U.com Rev 0; 6/07 KIT ATION EVALU LE B A IL A AV Mixed-Signal Microcontroller with Analog Comparators, LCD, and RTC General Description The MAXQ3100 microcontroller is a low-power, 16-bit RISC device that incorporates an integrated liquid-crystal display (LCD) interface that can drive up to 160 segments, two analog comparators with precision internal 1.25V reference voltage, and a real-time clock (RTC) module with a dedicated battery-backup supply. An internal temperature sensor allows software to monitor device temperature and optionally interrupt to alert when a temperature conversion is complete. The MAXQ3100 is uniquely suited for single-phase electricity metering applications that require an external analog front-end, but can be used in any application that requires high-performance operation. The device operates at a fixed 4.194MHz, generated from the 32.76kHz RTC crystal. The device has 8kWords of EEPROM, 512 words of RAM, three 16-bit timers, and two universal synchronous/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.
