Rev 1; 8/05

High-Precision ADC

Mixed-Signal Microcontroller

General Description

Features

♦ High-Performance, Low-Power, 16-Bit RISC Core

DC to 8MHz Operation, Approaching 1MIPS

per MHz

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 (DV

= 3.3V). The

16-Bit Instruction Word, 16-Bit Data Bus

16 x 16-Bit, General-Purpose Working Registers

Optimized for C-Compiler (High-Speed/Density

Code)

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.
