8-bit direct LCD-drive microcontrollers from Microchip

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.
