MAXQ2000
Low-Power LCD Microcontroller

Flexibility to use external resistors to adjust drive volt-
ages and current capacity
A simple LCD-segmented glass interface example
demonstrates the minimal hardware required to inter-
face to a MAXQ2000 microcontroller. A two-character
LCD is controlled, with each character containing
seven segments plus decimal point. The LCD controller
is configured for 1/2 duty cycle operation, meaning the
active segment is controlled using a combination of
segment signals, and COM0 or COM1 signals are used
to select the active display.
Applications
The low-power, high-performance RISC architecture of
the MAXQ2000 makes it an excellent fit for many
portable or battery-powered applications that require
cost-effective computing. The high-throughput core is
complemented by a 16-bit hardware multiplier-accumu-
lator, allowing the implementation of sophisticated com-
putational algorithms. Applications benefit from a wide
range of peripheral interfaces, allowing the microcon-
troller to communicate with many external devices. With
integrated LCD support of up to 100 or 132 segments,
applications can support complex user interfaces.
Displays are driven directly with no additional external
hardware required. Contrast can be adjusted using a
built-in, adjustable resistor. The simplified architecture
reduces component count and board space, critical
factors in the design of portable systems.
The MAXQ2000 is ideally suited for applications such
as medical instrumentation, portable blood glucose
equipment, and data collection devices. For blood glu-
cose measurement, the microcontroller integrates an
SPI interface that directly connects with analog front
ends for measuring test strips.
