The MA180027 Plug-In Module is small circuit processor boards used with the development board to evaluate PIC18F87K90 MCU. MCU features nanoWatt XLP technology and the Charge Time Measurement Unit (CTMU) module, provide ideal solutions for battery powered LCD applications utilizing touch interfaces. With 24 channels of capacitive touch sensing in an 80 pin package, these MCUs enable higher system integration combining large segmented LCDs with the capability for a high number of touch sliders, buttons and keys or touch screen technology. The PIM goes on the 80 pin socket on the PICDEM LCD 2 Demo Board and changes the output of the voltage regulator on the board to the proper voltage level for these parts. This enables users to quickly evaluate the new PIC18FK LCD Flash devices without having to buy a completely new demo board. It can be used stand alone in a custom application.
