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.
+ Denotes a lead(Pb)-free/RoHS-compliant package.
