Microchip announces the PIC18F87J90 8-bit direct LCD-drive microcontrollers (MCUs) with nanoWatt Technology, the first 8-bit MCUs to include Real-Time Clock & Calendar (RTCC) and Charge Time Measurement Unit (CTMU) peripherals, enabling capacitive touch-sensitive applications or precise time measurement.
The PIC18F87J90 offer 64- to 128kbyte of Flash and 4kbyte of RAM, extending the memory reach and peripheral set of Microchip´s LCD MCU portfolio. Furthermore, 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 unique 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. With this peripheral set, engineers can quickly and easily add user interfaces 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 (part no. DM163030 - $125) in combination with the PIC18F87J90 Plug-in Module (part no. MA180025 - $25), which includes capacitive-touch buttons. Both are available today at www.microchipdirect.com.
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 (part no. DV164035). The MPLAB IDE now comes with the free Segmented Display GUI, making it easier to generate the code needed to drive LCD displays.
