Microcontroller with Internal Voltage Regulator,  
Piezoelectric Horn Driver, and Comparator  
General Description  
Features  
♦ High-Performance, Low-Power, 16-Bit RISC Core  
DC to 3.58MHz Operation, Approaching 1MIPS  
per MHz  
The MAXQ3210 microcontroller is a low-power, 16-bit  
RISC device that incorporates a driver for a high-output  
piezoelectric horn/transducer, an analog comparator,  
and a high-current I/O pin that directly drives an LED.  
The device is uniquely suited for cost-conscious appli-  
cations such as chemical detectors, alarm systems,  
and white goods, but can be used in any application  
that requires high-performance and low-power opera-  
tion. The high-performance 16-bit RISC core and 8-bit  
accumulators are complemented by standard ameni-  
ties such as timers and digital I/O. The power con-  
sumption per MIPS ratio is among the best in the 16-bit  
microcontroller industry.  
Low-Cost Operation from “Colorburst” Crystal or RC  
Oscillator  
6V to 9.5V External Voltage Supply Operates from  
Single 9V Battery  
5.0V Nominal Internal Operation  
Up to 15 General-Purpose I/O Pins  
33 Instructions, Most Single-Cycle  
Three Independent Data Pointers Accelerate Data  
Movement with Automatic Increment/Decrement  
Two Loop Counters  
4-Level Hardware Stack  
16-Bit Instruction Word, 16-Bit Data Bus  
16 x 8-Bit Accumulators  
The MAXQ3210 is powered directly from a 6V to 9.5V  
source, such as a battery, but an internal voltage regu-  
lator operates the core at 5V. The microcontroller also  
provides a flag if the input voltage supply falls below  
JTAG Debug/Visibility Port  
the low-batttery detection threshold (V ), which can be  
BF  
♦ Program and Data Memory  
1kWord EEPROM Program Memory, Mask ROM for  
High-Volume Applications  
used to signal a low-voltage condition of the 9V battery.  
The MAXQ3212 is a general-purpose version of the  
MAXQ3210 that is powered directly from an external  
5.0V supply.  
128 Bytes EEPROM Data Memory  
60,000 EEPROM Write/Erase Cycles  
64 Bytes SRAM Data Memory  
A 1kWord EEPROM program memory stores customer  
application code and software algorithms. Software is  
programmable in-system by the ROM-based boot-  
loader and also in-application programmable under  
user software control. The device provides 64 bytes of  
volatile SRAM and 128 bytes of EEPROM in the data  
memory space. Contact Dallas Semiconductor con-  
cerning the availability of ROM-based devices for high-  
volume, low-cost applications.  
In-System Programming  
♦ Peripheral Features  
Piezoelectric Horn Driver  
16-Bit Programmable Timer/Counter with Prescaler  
High-Current I/O Pin Suitable for LED Drive  
Programmable Watchdog Timer  
Selectable Power-Fail Reset  
Power-On Reset (POR)  
Wake-Up Timer  
Internal 8kHz Ring Oscillator  
Applications  
♦ Flexible Programming Interface  
Integrated Bootloader  
Gas and Chemical  
Sensors  
Electrochemical and  
Optical Sensors  
In-System/In-Application Programming of EEPROM  
Security Alarm Systems  
Environmental Systems  
Battery-Powered and  
Portable Devices  
Home Appliances  
Thermostats/Humidity  
Sensors  
Through JTAG  
♦ Ultra-Low-Power Consumption  
< 6mA at 3.58MHz  
5.5µA Standby Current (typ)  
Low-Power Divide-by-256 Mode  
♦ Analog Features  
Typical Operating Circuits, Pin Configuration, and Ordering  
Information appear at end of data sheet.  
Analog Comparator Uses Internal or External Voltage  
Reference  
+2.5V Reference Output Available  
On-Chip Voltage Regulator Supports Up to 9.5V as  
Power Supply  
Low-Battery Detection  
5V Regulated Output Available, Up to 50mA
