SCN2652 - NXP

SCN2652 (SCN2652 / SCN68652) Multi-protocol communications controller MPCC

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.

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
