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.
