Microchip expands CAN microcontroller line with very low power 8-bit MCUs

March 11, 2011 // By Christoph Hammerschmidt
Aiming at automotive, industrial and medical markets, Microchip Technology has introduced the PIC18F “K80” 8-bit CAN microcontrollers (MCUs) featuring 1.8 – 5.5V operation and eXtreme Low Power (XLP) technology. The vendor claims that the device's sleep current consumption of less than 20 nA is the lowest in industry.

Featuring an on-chip 12-bit Analog-to-Digital Converter (ADC) and a peripheral that enables capacitive touch-sensing user interfaces, Microchip positions the MCUs for applications in automotive environments – for instance body control modules, lighting, door/seat/steering/window control or HVAC control. Another potential application field is industrial applications where the microcontrollers could be used in security systems, elevators and escalators, as well as medical markets. In this segment, Microchip sees glucose meters, patient-monitoring devices as good application examples.

The PIC18F K80 CAN MCU family enables smaller, more cost-effective and robust control with its integrated CAN peripheral for automotive and industrial applications. For medical applications that require low power and high accuracy, the MCUs deliver best-in-industry current ratings for longer battery life, as well as the on-chip 12-bit ADC and touch-sensing peripheral for advanced sensors.

Development Support

Microchip also announced two PIC18 Explorer Board Plug-In Modules (PIMs) for the PIC18F K80 MCUs, today—the 44-pin PIC18F46K80 (part # MA180031, $25) and the 64-pin PIC18F66K80 (part # MA180032, $25) PIMs. For the implementation and evaluation of CAN, Microchip's CAN/LIN PICtail (Plus) Daughter Board (part # AC164130-2, $45) may be used in conjunction with its PIC18 Explorer or Explorer 16 development boards.

The PIC18F45K80, PIC18F46K80, PIC18F65K80 and PIC18F66K80 MCUs are available in 44- and 64-pin TQFP and QFN packages. Additionally, the PIC18F45K80, PIC18F46K80 MCUs are available in a 40-pin PDIP package. The PIC18F25K80 and PIC18F26K80 MCUs are available in 28-pin QFN, SOIC, SPDIP and SSOP packages.

Pricing starts at $1.84 each, in 10,000-unit quantities. Samples are available.
