TEWS TECHNOLOGIES today announced the TPMC863, a new synchronous/asynchronous serial PMC module with four high speed communication channels. The serial communication controller is implemented in FPGA logic, combined with the bus master capable PCI interface. It guarantees long term availability with the option to implement additional application specific functions for customers. The TPMC863, designed for data communications, LAN/WAN networking, military communications, traffic control, simulation, and telecommunications applications is the successor of the discontinued TPMC862 providing similar functionality as well as full connector and pin-out compatibility.
Several serial communication protocols are supported by each channel, such as asynchronous, isochronous, synchronous and HDLC mode. In addition, a maximum data rate of 10 Mbit/sec is provided for synchronous protocols and 2 Mbit/sec is supported for asynchronous protocols.
Multiprotocol transceivers are used for the line interface. The physical interface of each channel can be independently software selected for EIA-232, EIA-422, EIA-449, EIA-530, EIA-530A, V.35, V.36 or X.21. Physical connection is either through front panel I/O with an HD68 SCSI-3 type connector or rear I/O via P14.
In order to reduce CPU overhead and increase data rates for critical applications, the TPMC863 features a receive and transmit FIFO of 512 long words (32 bit) per channel. Data transfer on the PCI bus is handled via TPMC863 initiated DMA cycles with minimum host/CPU intervention. In addition, several interrupt sources can generate interrupts on INTA for each channel, and interrupts may be enabled or disabled separately.
Asynchronous and basic synchronous support for major operating systems such as Windows, Linux, VxWorks, and QNX is available.
