The integrated LCD module can provide software-programmable contrast control. This can boost the LCD voltage, dim the display, or compensate for operating environment including temperature and ambient lighting. These features can improve display appearance, even with a lower cost LCD glass. Other key device features include an internal oscillator, higher-speed low-voltage performance (up to 10MIPS at 3V) and more LCD segment drive on 64-pin devices.
Example applications for the new family include dashboard displays; handheld terminals; appliance display/control units; utility meters; home security systems and exercise equipment.
Additional features include:
• Up to 32 Kbytes of self-programming Flash program memory
• Up to 2 Kbytes of SRAM
• Enhanced LCD module supporting up to 192 pixels (4 commons x 48 segments)
• Software Controllable Internal Oscillator (32 kHz to 8 MHz)
• 12 Channel, 100k samples-per-second 10-bit A-to-D converter
• Two Analog Comparators, with internal Voltage Reference
• Brownout and Low-Voltage Detection
• Serial Communications including I2C, SPI and USART
• Two Capture/Compare/PWM Modules
All six members of the family are supported by Microchip’s high-performance development systems, including the MPLAB Integrated Development Environment; the MPLAB C18 C Compiler; the MPLAB ICD 2 In-Circuit Debugger, the PICDEM™ HPC Explorer Board (part number DM183022) and the forthcoming PICDEM LCD 2 Demo Board (part # DM163030).
All six of the PIC18F85J90 LCD microcontrollers are available for sampling and in volume. The PIC18F85J90/84J90/83J90 are available in an 80-pin TQFP package, while the PIC18F65J90/64J90/63J90 are available in a 64-pin TQFP package.
