Microchip PIC18F87J93 8-bit PIC Microcontrollers

Microchip Technology introduced the PIC18F87J93 8-bit PIC microcontroller (MCU) family for medical and metering applications. The PIC18F87J93 direct LCD-drive MCUs feature up to 16 channels of 12-bit Analog-to-Digital Conversion (ADC), the mTouch Charge Time Measurement Unit (CTMU) peripheral for capacitive touch sensing, and a hardware Real-Time Clock and Calendar (RTCC). Pricing for the four-member PIC18F87J93 family starts at $2.71 each, in 10,000-unit quantities. The PIC18F66J93 and PIC18F67J93 MCUs are available in a 64-pin TQFP package, while the PIC18F86J93 and PIC18F87J93 MCUs are available in an 80-pin TQFP package.

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.
