Rev 1; 5/06 www.DataSheet4U.com 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 applications such as chemical detectors, alarm systems, and white goods, but can be used in any application that requires high-performance and low-power operation. The high-performance 16-bit RISC core and 8-bit accumulators are complemented by standard amenities such as timers and digital I/O. The power consumption 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 regulator 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 bootloader 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 concerning the availability of ROM-based devices for highvolume, low-cost applications.
