Microchip Introduces Industry's First Low-Power 8-bit Microcontrollers With LCD Driver, 5V Operation and On-Chip 12-bit ADC

Microchip Technology » PIC18F65K90, PIC18F66K90, PIC18F67K90, PIC18F85K90, PIC18F86K90, PIC18F87K90

Microchip Technology Inc., announced the PIC18F “K90” 8-bit microcontroller (MCU) family—the industry’s first and only low-power, 5V, 8-bit MCUs that include an on-chip LCD driver module and 12-bit Analog-to-Digital Converter (ADC). The new MCUs feature nanoWatt XLP technology for eXtreme Low Power consumption, with industry-leading sleep currents down to 20 nA. The family comes in 64- and 80-pin packages, with memory options that range from 32 KB to 128 KB of Flash memory, up to 4 KB of RAM and 1 KB 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.

Microchip PIC18F87K90

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.

Development Tool Support

A Plug-In Module (PIM) for the PIC18F87K90 MCU was also announced, today (part # MA180027, $25). The PIM can be used with the PICDEM LCD 2 Demo Board (part # DM163030, $125), or stand-alone in a custom application.
