Multi-protocol communications controller (MPCC)
SCN2652/SCN68652
DESCRIPTION
The SCN2652/68652 Multi-Protocol Communications Controller (MPCC) is a monolithic n-channel MOS LSI circuit that formats, transmits and receives synchronous serial data while supporting bit-oriented or byte control protocols. The chip is TTL compatible, operates from a single +5V supply, and can interface to a processor with an 8 or 16-bit bidirectional data bus.
FEATURES
DC to 2Mbps data rate Bit-oriented protocols (BOP): SDLC, ADCCP, HDLC Byte-control protocols (BCP): DDCMP, BISYNC (external CRC) Programmable operation
– 8 or 16-bit tri-state data bus – Error control – CRC or VRC or none – Character length – 1 to 8 bits for BOP or 5 to 8 bits for BCP – SYNC or secondary station address comparison for BCP-BOP – Idle transmission of SYNC/FLAG or MARK for BCP-BOP
APPLICATIONS
Intelligent terminals Line controllers Network processors Front end communications Remote data concentrators Communication test equipment Computer to computer links
Automatic detection and generation of special BOP control
sequences, i.e., FLAG, ABORT, GA
Zero insertion and deletion for BOP Short character detection for last BOP data character SYNC generation, detection, and stripping ...
