com Rev 0; 6/07 KIT ATION EVALU LE B A IL A AV Mixed-Signal Microcontroller with Analog Comparators, LCD, and RTC General Description The MAXQ3100 microcontroller is a low-power, 16-bit RISC device that incorporates an integrated liquid-crystal display (LCD) interface that can drive up to 160 segments, two analog comparators with precision internal 1.
25V reference voltage, and a real-time clock (RTC) module with a dedicated battery-backup supply.
An internal temperature sensor allows software to monitor device temperature and optionally interrupt to alert when a temperature conversion is complete.
The MAXQ3100 is uniquely suited for single-phase electricity metering applications that require an external analog front-end, but can be used in any application that requires high-performance operation.
The device operates at a fixed 4.
194MHz, generated from the 32.
76kHz RTC crystal.
The device has 8kWords of EEPROM, 512 words of RAM, three 16-bit timers, and two universal synchronous/asynchronous receiver/transmitters (USARTs).
The microcontroller core and I/O are powered by a single 3.
3V supply, and an additional battery supply keeps the RTC running during power outages.
Features ♦ High-Performance, Low-Power, 16-Bit RISC Core 4.
194MHz Operation, Approaching 1MIPS per MHz 3.
3V Core and I/O 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-Compiler (High-Speed/Density Code) ♦ Program and Data Memory 8kWords EEPROM 200,000 EEPROM Write/Erase Cycles 512 Words of Internal Data RAM JTAG-Compatible Debug Port Bootloader for Programming ♦ Peripheral Features Up to 27 General-Purpose I/O Pins, Most 5V Tolerant 160-Segment LCD Driver Up to 4 COM and 40 Segments Static, 1/2, and 1/3 LCD Bias Supported No External Resistors Required Two Analog Comparators with ...
