General Description
The MAXQ2000 microcontroller is a low-power, 16-bit
device that incorporates a liquid-crystal display (LCD)
interface that can drive up to 100 (-RBX) or 132 (-RAX)
segments. The MAXQ2000 is uniquely suited for the
blood-glucose monitoring market, but can be used in
any application that requires high performance and low-
power operation. The device can operate at a maximum
of either 14MHz (V
DD
> 1.8V) or 20MHz (V
DD
> 2.25V).
The MAXQ2000 has 32kWords of flash memory, 1kWord
of RAM, three 16-bit timers, and one or two universal
synchronous/asynchronous receiver/transmitters
(UARTs). Flash memory aids prototyping and low-vol-
ume production. The microcontroller core is powered by
a 1.8V supply, with a separate I/O supply for optimum
flexibility. An ultra-low-power sleep mode makes these
parts ideal for battery-powered, portable equipment.
