Dual Universal Serial Communications Controller Duscc

The Philips Semiconductors SCN26562 Dual Universal Serial Communications Controller (DUSCC) is a single-chip MOS-LSI Communications device that provides two independent, multi-protocol, full-duplex receiver/transmitter channels in a single package. It supports bit-oriented and character-oriented (byte count and byte control) synchronous data link controls as well as asynchronous protocols. The SCN26562 Interfaces to synchronous bus MPUs and is capable of program-polled, interrupt driven, block-move or DMA data transfers. The operating mode and data format of each channel CAN be programmed independently. Each channel consists of a receiver, a transmitter, a 16-bit multi-function Counter Timer a digital phase-locked loop (DPLL), a parity/CRC generator and checker, and associated control circuits. The two channels share a common bit rate generator (BRG), operating directly from a crystal or an external Clock which provides 16 common bit rates simultaneously. The operating rate for the receiver and transmitter of each channel CAN be independently selected from the BRG, the DPLL, the Counter Timer or from an external 1X or 16X Clock making the DUSCC well suited for dual-speed channel applications. Data rates up to 4Mbits per second are supported. By NXP Semiconductors
