<p>A low power reduced size serial device protocol translator including a slave controller (26) and detection circuit (27, 28) for detecting start and stop conditions on serial data (10) (SDA) and serial clock (11) (SCL) lines in a serial communication system is described. The start and stop condition detector includes two flip-flops (27, 28); which are only enabled and clocked when either a start or stop condition is occurring. A master device resides on a first printed circuit board (PCB) and communicates with slave devices on a second PCB having more than one type of serial communication protocol. The translator resides on the same PCB as the slave devices thus requiring that only the serial buses corresponding to the master device protocol type to be physically coupled across the two PCB's interconnection interface.</p> |
