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.
APPLICATIONS
• Intelligent terminals
• Line controllers
• Network processors
• Front end communications
• Remote data concentrators
• Communication test equipment
• Computer to computer links
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
• 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 for BCP
• Maintenance mode for self-testing
• TTL compatible
• Single +5V supply

NOTES:
1. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or at any other condition above those indicated in the operation sections of this specification
is not implied.
2. For operating at elevated temperatures the device must be derated based on +150°C maximum junction temperature.
3. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying any voltages larger than the rated maxima.
4. Parameters are valid over operating temperature range unless otherwise specified. See ordering code table for applicable temperature
range and operating supply range.
