TPMC862 4 Channel High Speed Synch/Asynch Serial Interface

Application Information

The TPMC862 is a standard single-width 32 bit PMC with

four high speed serial data communication channels.

An

Infineon

PEF 20534

DMA

Supported

Serial

Communication Controller (DSCC4) with integrated bus

master PCI interface is used.

Several interrupt sources can generate interrupts on INTA

for each channel. Interrupts can be enabled and disabled

separately.

A 14.7456 MHz oscillator provides standard asynchronous

baud rates. An additional 24 MHz oscillator is provided for

other baud rates. A 10 MHz oscillator is used for the

maximum synchronous baud rate of 10Mbit/s.

Each channel can support many serial communication

protocols such as HDLC, SDLC, PPP, asynchronous,

monosynchronous, bisynchronous.

Multiprotocol transceivers are used for the line interface.

The physical interface can be selected by software

individually for each channel as EIA-232, EIA-422, EIA-

449, EIA-530, EIA-530A, V.35, V.36 or X.21.

The TPMC862 supports Receive Data (RxD +/-), Transmit

Data (TxD +/-), Receive Clock (RxC +/-), Transmit Clock

(TxC +/-),

Ready-To-Send

(RTS +/-),

Clear-To-Send

(CTS +/-), Carrier-Detect (CD +/-) and GND for each

channel. Additionally serial channel three provides Data-

Set-Ready

(DSR3 +/-)

and

Data-Terminal-Ready

(DTR3 +/-), both over front I/O only.

The DSCC4 contains a central receive and transmit FIFO

of 128 long words (32 bit) each. Additionally each channel

has a receive FIFO (17 long words deep) and a transmit

FIFO (8 long words deep).

The TPMC862 provides front panel I/O via a HD68 SCSI-3

type connector and rear I/O via P14.

For First Time Users the Engineering Documentation

TPMC862-ED

is

recommended.

The

Engineering

Documentation includes TPMC862-DOC, schematics and

data sheets.

Software

Support

(TDRV001-SW-xx)

for

different

operating systems is available.
