DATA SHEET MOS INTEGRATED CIRCUIT µPD72042 LSI DEVICES FOR Inter Equipment BusTM (IEBus TM) PROTOCOL CONTROL The µPD72042 is a microcomputer peripheral LSI device for IEBus protocol control. The µPD72042 performs all the processing required for layers 1 and 2 of the IEBus. The devices incorporate large transmission and reception buffers, allowing the microcomputer to perform IEBus operations without interruption. They also contain an IEBus driver and receiver, allowing them to directly connected to the bus directly. FEATURES • Control of layers 1 and 2 of the IEBus protocol • Support of a multi-master scheme • Broadcast function • Two communication modes having different transmission speeds can be selected. • Microcomputer interface Three-/two-wire serial I/O, Transfer starting with MSB • Program crashes can be detected by means of a watchdog timer. • Low power consumption (standby mode): Transmission speed Mode 0 Mode 1 q q 50 µA (max) • Oscillator frequency (f ): X 6 MHz Approx. 3.9 Kbps Approx. 17 Kbps • frequency accuracy: ±1.5% • Operating voltage: 5 V ±10% Built-in IEBus driver and receiver Transmission and reception buffers Transmission buffer Reception buffer : 33 bytes, FIFO : 40 bytes, FIFO (capable of holding more than one frame of reception data.)
