Microcontroller with Internal Voltage Regulator,
Piezoelectric Horn Driver, and Comparator
General Description
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.
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
the low-batttery detection threshold (VBF), which can be
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.
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.

J-STD-020 Specification
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
