PIC18F87K90 FAMILY
The
pin-compatible with other PIC18 families, such as the
PIC18F8720, PIC18F8722, PIC18F85J11, PIC18F8490,
PIC18F85J90, PIC18F87J90 and PIC18F87J93 families
of microcontrollers with LCD drivers. This allows a new
dimension to the evolution of applications, allowing
developers to select different price points within
Microchip’s PIC18 portfolio, while maintaining a similar
feature set.
1.2
The on-chip LCD driver includes many features that
ease the integration of displays in low-power
applications. These include an integrated internal
resistor ladder, so bias voltages can be generated
internally. This enables software-controlled contrast
control and eliminates the need for external bias
voltage resistors.

has differential ADC. It incorporates program-
mable acquisition time, allowing for a channel to
be selected and a conversion to be initiated with-
out waiting for a sampling period, and thus,
reducing code overhead.
CTMU is a flexible analog module that provides accu-
rate differential time measurement between pulse
sources, as well as asynchronous pulse generation.
Together with other on-chip analog modules, the
CTMU can precisely measure time, measure
capacitance or relative changes in capacitance, or
generate output pulses that are independent of the
system clock.
