8 bit MCU with CAN consumes less than 20nA while sleeping

The new PIC18FK80 8-bit CAN microcontrollers (MCUs) from Microchip operate from 1.8 - 5.5V Input Voltage and consume sleep current of less than 20 nA. The new MCUs feature an on-chip 12-bit Analog-to-Digital Converter (ADC) and a peripheral supporting mTouch capacitive touch-sensing user interfaces.
Applications targeted include automotive (e.g. body control modules, automotive lighting, door/seat/steering/window control, HVAC control), industrial (e.g. security systems, elevators and escalators) and medical (e.g. glucose meters, patient-monitoring devices) markets.


"The PIC18F K80 family was developed for designers who need to add cost-effective CAN communication to their applications with extremely low power sleep and active modes, and robust operation up to 5.5 Volts," said Mitch Obolsky, vice president of Microchip's Advanced Microcontroller Architecture Division. "The new MCUs offer a migration path for our popular PIC18F4680 CAN family, serving a wide spectrum of applications."

Editorial Product Rating: * (Average). Microchip claims these MCUs feature lowest sleep current consumption of less than 20 nA, but we noticed the Atmel's 32-bit AVR UC3L series consume only 9 nA. 32 bit MCUs consuming less sleep current than 8 bit MCU is something laudable.
