MCU family with integrated LCD module enhanced

11 July 2007 DSP, Micros & Memory

Microchip has announced six new members of its 8-bit PIC microcontroller family featuring an integrated 192-pixel liquid crystal display (LCD) module.

The PIC18F85J90 family doubles the amount of Flash and RAM memory available in 64- and 80-pin PIC18 LCD devices. This increased memory enables users to add more complex functionality such as speech playback, while taking advantage of the cost savings offered by the PIC18 'J' series' 3-volt manufacturing process.

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, high-speed low-voltage performance (up to 10 MIPS at 3 V) and more LCD segment drive on 64-pin devices.

Example applications for this product family include dashboard displays, handheld terminals, appliance display/control units, utility meters, home security systems and exercise equipment.

Additional features of these MCUs include: up to 32 KBytes of self-programming Flash program memory; up to 2 KBytes of SRAM; software controllable internal oscillator (32 kHz to 8 MHz); 12-channel, 100 ksps, 10-bit ADC; two analog comparators with internal voltage reference; brownout and low-voltage detection; serial communications including I²C, SPI and USART; two capture/compare/PWM modules
