General Description

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 synchro-

nous/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 abili-

ty to selectively disable peripherals, and multiple

power-saving operating modes.
