Read our full Embedded World coverage Microchip has revealed microcontrollers that cut operating power to as low as 42uA/MHz - the 1822 and 1947.
Announced at Embedded World in Nuremberg, there are 11 devices spread across the PIC 12 and PIC 16 families.
"In our existing XLP (extra low power) devices, we have been concentrating on sleep power consumption. Now we are concentrating on active power consumption," marketing manager Lucio Di Jasio told Electronics Weekly.
The headline devices are the 8pin PIC12LF1822 and the 64pin 16LF1947 – the ´LF1 in their name indicates low operating power.
The 1822 includes 3.5kbyte of flash and consumes 42uA/MHz at 1.8V and 73uA/MHz at 3.0V.
At the same voltages, the 28kbyte 1947 draws 53 and 85uA respectively.
Both will operate at 2MHz on only 190uA from a 3032 coin cell, claimed Di Jasio.
At the same time, the firm has updated its LCD driver block, adding a low power mode that reduces LCD drive power when only a static image has to be maintained by LF1 chips.
