LCD CONTROLLER WITH LOW POWER MODE

An LCD controller comprises a host interface control block for providing a connection between the LCD controller and a master controller. The master controller initiates a low power mode of operation for the LCD controller through the host interface control block. At least a portion of a plurality of input/output pins provide a connection to at least one LCD display for the LCD controller. An LCD static display controller within the LCD controller drives the at least one LCD display in a static display mode responsive to entry of the LCD controller into the low power mode of operation. A real time clock provides a clock signal to the LCD static display controller in the low power mode of operation. Power circuitry within the LCD controller selectively disables a regulated voltage provided to circuitry in the LCD controller that is not required to operate the LCD static display controller and the real time clock circuit in the low power mode of operation.
