Abstract
A microcontroller includes a processing unit having a processing unit having normal power mode of operation and a low power mode of operation. The processing unit further having digital circuitry connected to the processing unit having a plurality of logic circuits associated therewith for processing digital values. A plurality of retention flip-flops are associated with the digital circuitry for storing a logical state of at least one or more of the logic circuits within the digital circuitry when the processing unit enters the low power mode of operation. The plurality of retention flip flops include a first type of transistors for operating in both the low and high power modes of operation and a second type of transistors for operation only in the normal mode of operation and wherein substantially the remainder of the digital circuitry in the processing unit comprises the second type of transistors.
