PEF20534H-10 - DMA Supported Serial Communication Controller with 4 Channels

1 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.

A 33-MHz/32-bit PCI bus Master/Slave interface with integrated high performance DMA

controllers provides data transfer from or to host memory with low bus utilization and

easy software handshaking.

An additional de-multiplexed bus interface mode is provided for integration in non-PCI

bus environments with little glue-logic depending on the bus type.

The DMA Controller operates on linked lists which are optimized for data communication

applications. Different control mechanisms allow easy software development well

adapted to the needs of special applications.

Large onchip FIFOs in combination with enhanced threshold control mechanisms allow

decoupling of traffic requirements on host bus and serial interfaces with little exception

probabilities such as data underuns or overflows.

In a PCI bus application an integrated Local Bus Interface (LBI) provides bridging

functionality to non PCI peripherals such as framers or line interface units (LIUs).

A Synchronous Serial Control (SSC) interface as well as a General Purpose Port (GPP)

allows covering application specific requirements without additional controllers.

Each of the four Serial Communication Controllers (SCC) contains an independent Baud

Rate Generator, DPLL, programmable protocol processing (HDLC, BISYNC, ASYNC

and PPP). Data rates of up to 2 Mbit/s (DPLL assisted modes, ASYNC, BISYNC),

10 Mbit/s (HDLC, PPP) and 52 Mbit/s (H-52 version) are supported. The channels can

also handle a large set of layer-2 protocol functions reducing bus and host CPU load.

Four channel specific timers are provided to support protocol functions.

The DSCC4 devices can be used in LAN-WAN inter-networking applications such as

Routers, Switches and Trunk cards and support the common V.35, ISDN BRI (S/T) or

Asynchronous Dial-up interfaces. Its new features provide powerful hardware and

software interfaces to develop high performance systems.
