A new low-power, 5V 8-bit microcontroller (MCU) family includes an on-chip LCD driver module and 12-bit Analog-to-Digital Converter (ADC). The PIC18F “K90” family from Microchip Technology features nano-watt XLP technology for eXtreme low-power consumption, with sleep currents down to 20 nA. The family comes in 64- and 80-pin packages, with memory options that range from 32 Kbyte to 128 Kbyte of flash memory, up to 4 Kbyte of RAM and 1 Kbyte of on-chip EEPROM. With 24 channels of mTouch capacitive touch sensing, these MCUs enable higher system integration—combining the capability to sense a large number of cap-touch sliders, buttons and keys with the ability to drive large, segmented LCDs.

According to Microchip, the PIC18F “K90” family represents a significant expansion of their high-end 8-bit LCD microcontroller offerings into the 5V operating range. These products are suitable for customers wanting to drive large, segmented LCDs, while consuming very low amounts of power for longer battery life. With this combination of features, these MCUs are well suited for applications in the home automation (e.g. thermostats, security systems, in-home displays), appliance (e.g. coffee makers, ranges, refrigerators); industrial (e.g. electronic door locks, metering, HVAC controls); medical (e.g. pulse oximeters, glucometers, digital thermometers, portable health-monitoring devices); and automotive (e.g. alarm systems, keyless entry, dashboard and center-stack displays) markets, among others.

A Plug-In Module (PIM) for the PIC18F87K90 MCU was also announced, today. The PIM can be used with the PICDEM LCD 2 Demo Board or stand-alone in a custom application. Designers can also use Microchip’s complete suite of standard development tools, including the user-friendly and free MPLAB IDE and corresponding suite of emulators, programmers and development boards, along with the free MPLAB C or HI-TECH C compiler for PIC18 MCUs. The PIC18F “K90” MCUs are available in 64- and 80-pin TQFP and 64-pin QFN packages, with prices starting at $2.42 each in 10,000 unit quantities.
