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 seg-
ments, two analog comparators with precision internal
1.25V reference voltage, and a real-time clock (RTC)
module with a dedicated battery-backup supply. An inter-
nal temperature sensor allows software to monitor device
temperature and optionally interrupt to alert when a tem-
perature conversion is complete. The MAXQ3100 is
uniquely suited for single-phase electricity metering appli-
cations that require an external analog front-end, but can
be used in any application that requires high-perfor-
mance 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/asyn-
chronous receiver/transmitters (USARTs). The microcon-
troller core and I/O are powered by a single 3.3V supply,
and an additional battery supply keeps the RTC running
during power outages.

J-STD-020 Specification
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
