Low-Power LCD Microcontroller

General Description

Features

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

DC to 20MHz Operation, Approaching 1MIPS per MHz

Dual 1.8V Core/3V I/O Enables Low Power/Flexible

Interfacing

The MAXQ2000 microcontroller is a low-power, 16-bit

device that incorporates a liquid-crystal display (LCD)

interface that can drive up to 100 (-RBX) or 132 (-RAX)

segments. The MAXQ2000 is uniquely suited for the

blood-glucose monitoring market, but can be used in

any application that requires high performance and low-

power operation. The device can operate at a maximum

33 Instructions, Most Single Cycle

Three Independent Data Pointers Accelerate Data

Movement with Automatic Increment/Decrement

16-Level Hardware Stack

16-Bit Instruction Word, 16-Bit Data Bus

16 x 16-Bit, General-Purpose Working Registers

Optimized for C-Complier (High-Speed/Density Code)

of either 14MHz (V

> 1.8V) or 20MHz (V

> 2.25V).

The MAXQ2000 has 32kWords of flash memory, 1kWord

of RAM, three 16-bit timers, and one or two universal

synchronous/asynchronous receiver/transmitters

(UARTs). Flash memory aids prototyping and low-vol-

ume production. The microcontroller core is powered by

a 1.8V supply, with a separate I/O supply for optimum

flexibility. An ultra-low-power sleep mode makes these

parts ideal for battery-powered, portable equipment.

♦ Program and Data Memory

32kWords Flash Memory, Mask ROM for High-

Volume Applications

10,000 Flash Write/Erase Cycles

1kWord of Internal Data RAM

JTAG/Serial Boot Loader for Programming

♦ Peripheral Features

Up to 50 General-Purpose I/O Pins

100/132 Segment LCD Driver

Up to 4 COM and 36 Segments

Static, 1/2, and 1/3 LCD Bias Supported

No External Resistors Required

Applications

Medical Instrumentation

Battery-Powered and Portable Devices

Electrochemical and Optical Sensors

Industrial Control

Data-Acquisition Systems and Data Loggers

Home Appliances

Consumer Electronics

Thermostats/Humidity Sensors

Security Sensors

Gas and Chemical Sensors

HVAC

SPI^TMand 1-Wire (-RAX Only) Hardware I/O Ports

One or Two Serial UARTs

One-Cycle, 16 x 16 Hardware Multiply/Accumulate

with 48-Bit Accumulator

Three 16-Bit Programmable Timers/Counters

8-Bit, Subsecond, System Timer/Alarm

32-Bit, Binary Real-Time Clock with Time-of-Day Alarm

Programmable Watchdog Timer

♦ Flexible Programming Interface

Bootloader Simplifies Programming

In-System Programming Through JTAG

Supports In-Application Programming of Flash Memory

Smart Transmitters

♦ Ultra-Low Power Consumption

190µA typ at 8MHz Flash Operation, PMM1 at 2.2V

700nA typ in Lowest Power Stop Mode

Typical Operating Circuit and Pin Configurations appear at

end of data sheet.

Low-Power 32kHz Mode and Divide-by-256 Mode
