PIC18F87J90 MCUs feature nanoWatt technology

Microchip has released the PIC18F87J90 8-bit direct LCD-drive microcontrollers (MCUs) with nanoWatt technology.

These 8-bit MCUs include real-time clock and calendar (RTCC) and charge time measurement unit (CTMU) peripherals, enabling capacitive touch-sensitive applications or precise time-measurement.

The PIC18F87J90s offer 64 to 128kbyte of Flash and 4kbyte of RAM, extending the memory reach and peripheral set of Microchip's LCD MCU portfolio.

They are pin-compatible with Microchip's PIC18F85J90 devices, providing an easy migration path across Microchip's entire LCD-drive MCU family, simplifying application upgrades.

The on-board LCD module contains a software-controlled contrast controller, providing display boost or dimming functionality to compensate for environmental variations such as lighting or temperature.

Microchip's nanoWatt technology helps systems maintain a low-power profile, even allowing the display driver to continue operating during sleep mode.

The RTCC also operates in sleep mode, ensuring real-time tracking isn't impeded by low-power operation.

This peripheral set lets engineers quickly and easily add user-interface features such as capacitive or inductive touch-sensing to their display applications.

To start designing with the PIC18F87J90 family, customers can use the PICDEMTM LCD 2 Demo Board in combination with the PIC18F87J90 plug-in module, which includes capacitive-touch buttons.

The PIC18F87J90 family is supported by Microchip's standard development tool suite, including the free MPLAB Integrated Development Environment, MPLAB C Compiler for PIC18 and the MPLAB ICD 3 in-circuit debugger.

The MPLAB IDE now comes with the free segmented display GUI, making it easier to generate the code needed to drive LCD displays.
