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).  
DD  
DD  
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  
SPITM and 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
