Chandler, AZ, U.S.A. --- (METERING.COM) --- July 15, 2009 - A new four member family of high performance 8-bit PIC® microcontrollers (MCUs) for metering and other applications has been announced by microcontroller and analog semiconductor provider Microchip Technology Inc.

The PIC18F87J93 8-bit direct LCD drive MCUs feature up to 16 channels of 12-bit analog-to-digital conversion (ADC), the mTouchTM charge time measurement unit (CTMU) peripheral for capacitive touch sensing, and a hardware real time clock and calendar (RTCC). With this enhanced analog functionality and rich peripheral set, the PIC18F87J93 family enables the highly precise measurements and sensors, as well as the high levels of integration that metering applications require.

The 64 and 80 pin PIC18F87J93 MCUs have memory options ranging from 64 to 128 kB Flash program memory and 4 kB RAM, and are pin-out compatible with Microchip’s entire LCD-drive MCU portfolio. The on-chip 12-bit ADC with up to 16 channels performs auto acquisition and works during sleep mode, enabling a low power, reliable analog interface. The on-chip hardware RTCC also works in sleep mode, to enable real-time clock and calendar functions with low power consumption. Additionally, the mTouch CTMU peripheral enables the addition of capacitive touch sensing user interfaces or precise time measurements, and lowers system costs. The LCD charge pump provides contrast control and maintains low-power ratings even with advanced feature sets.

“Microchip’s PIC18F87J93 family expands our portfolio of cost effective LCD products.  For metering applications, their 12-bit ADC, mTouch peripheral and extended memory deliver a cost-effective feature set,” said Mitch Obolsky, vice president of Microchip’s Advanced Microcontroller Architecture Division. “The new devices offer a drop-in upgrade in features and memory to our popular and low-cost PIC18F85J90 LCD family.”
