Chandler, Ariz. Microchip Technology Inc. has introduced six new members of the 8-bit PIC microcontroller family with integrated Liquid Crystal Display (LCD) module. The new PIC18F85J90 series doubles the amount of Flash and RAM memory over existing 64- and 80-pin family members.
The PIC18F85J90 series delivers 8 to 32 Kbytes of self-programming Flash program memory, and up to 2 Kbytes of SRAM. The devices also feature an enhanced LCD module with four multiplex commons and up to 48 segments driving up to 192 pixels.
Other features include seven power-managed states, a 32 kHz to 8 MHz internal oscillator, high core performance of up to 40 MHz at 3 V, and a 10-bit analog-to-digital converter with up to 12 signal channels and 100,000 samples-per-second.
Targeting human-interface applications requiring embedded control including thermostats, utility meters and medical instrumentation, this increased amount of memory enables users to add more complex functionality such as speech playback and larger amounts of self-programming memory allocation, while taking advantage of the cost savings offered by the PIC18 "J" series' 3-volt manufacturing process technology, said Microchip.
The LCD module onboard the PIC18F85J90 series enables a software-programmable contrast controller, which can boost the LCD voltage, dim the display, or compensate for environmental elements like temperature and lighting. These features lower the cost of the LCD glass while improving the display appearance, making advanced LCD functionality affordable to a new class of embedded display application, said Microchip.
To reduce time to market, all six microcontrollers are supported by Microchip's standard development systems including: MPLAB Integrated Development Environment (IDE), MPLAB C18 C Compiler, MPLAB ICD 2 In-Circuit Debugger, and the PICDEM HPC Explorer Board (part # DM183022). In addition, the PICDEM LCD 2 Demo Board (part # DM163030) is expected to be available in May to ease development with this series' advanced LCD features.
Pricing: Starts at $2.37 each in quantities of 10,000. The PIC18F85J90/84J90/83J90 devices are available in 80-pin TQFP packages, while the PIC18F65J90/64J90/63J90 parts are available in 64-pin TQFP packages.
Availability: All six of the PIC18F85J90 LCD microcontrollers are available for general sampling and volume production.
