Overview
The DSCC4 is a DMA Supported Serial Communication Controller with four independent serial channels1). The serial channels are derived from updated protocol logic of the ESCC device family providing a large set of protocol support and variety in serial interface configuration. This allows easy integration to different environments and applications.

FEATUREs
• Serial communication controllers (SCCs)
    - Four independent channels
    - Full duplex data rates on each channel of up to 10 Mbit/s sync - 2 Mbit/s with DPLL, 2 Mbit/s async
    - Full duplex data rate of up to 52 Mbit/s on any two channels in high speed mode (HDLC: Address Mode 0 and extended transparent protocol mode); up to 45 Mbit/s on any two channels in high speed mode (HDLC: PPP modes). The aggregate bandwith for all channels is limited to 108 Mbit/s per direction.
    - 17 DWORDs deep receive FIFO per SCC (+ 128 DWORDs central receive FIFO).
    - 8 DWORDs deep transmit FIFO per SCC (+ 128 DWORDs central transmit FIFO).

• Serial Interface
    - On chip clock generation or external clock sources
    - On chip DPLLs for clock recovery
    - Baud rate generator
    - Clock gating signals
    - Clock gapping capability
    - Programmable time-slot capability for connection to TDM interfaces (e.g. T1, E1)
    - NRZ, NRZI, FM and Manchester data encoding
    - Optional data flow control using modem control lines (RTS, CTS, CD)
    - Support of bus configuration by collision detection and resolution
