16-Bit Mixed-Signal Microcontroller with LCD Interface

Integrated Microcontroller with 12-Bit ADC, 16-Bit RISC Core and Ultra-Low-Power Stop Mode (370nA typ)

Please check latest availability status for a specific part variant.


The MAXQ2010 microcontroller is a low-power, 16-bit device that incorporates a high-performance, 12-bit, multichannel ADC and a liquid-crystal display (LCD) interface. A combination of high performance, low power, and mixed-signal integration makes the MAXQ2010 ideal for a wide variety of applications.

The MAXQ2010 has 64KB of flash memory, 2KB of RAM, three 16-bit timers, and two universal synchronous/asynchronous receiver/transmitters (USARTs). Flash memory aids prototyping and is available for mass production. Mask ROM versions are available for large production volumes when cost is a critical factor. The microcontroller runs from a 2.7V to 3.6V operating supply. For the ultimate in low-power performance, the MAXQ2010 includes a low-power sleep mode, the ability to selectively disable peripherals, and multiple power-saving operating modes.
