General Description
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.
