TEWS TECHNOLOGIES Introduces Extended Temperature and High-Density Full/Half Duplex Serial Communication cPCI Module

Halstenbek, Germany – July 21st, 2010. TEWS TECHNOLOGIES extends its tradition of delivering high-density I/O solutions to CompactPCI with its introduction of the 4 channel TCP467, an extended temperature and high density 3U CompactPCI Serial Communications Controller. The TCP467 is ideal for applications in transportation, communications, process control, and COTS.

The new module provides 4 channels of high performance RS232/RS422/RS485 selectable serial connectivity. The serial channels can be individually programmed to operate as RS232, RS422 or RS485 full/half duplex interfaces. In addition, programmable termination is provided for the RS422/RS485 interfaces. After power-up all serial I/O lines are in a high impedance state for critical applications. Physical connection is achieved through front panel I/O with four RJ45 Modular Jack connectors.
Each RS232 channel supports RxD, TxD, RTS, CTS and GND. RS422 and RS485 full duplex supports a four wire interface (RX+, RX-, TX+, TX-) plus ground (GND). RS485 half duplex supports a two wire interface (DX+, DX-) plus ground (GND).

All channels generate interrupts on CompactPCI interrupt INTA. For fast interrupt source detection the UART provides a special Global Interrupt Source Register.

Each serial channel of the cPCI module has separate 64 byte receive and transmit FIFOs to significantly reduce the processing overhead required to provide data transactions to the transceivers. The FIFO trigger levels are programmable, and the baud rate is individually selectable up to 921.6 kbps for RS232 channels and 5.5296 Mbps for RS422/RS485 channels. The UART offers readable FIFO levels.

The TCP467 operates in extended temperature range (-40°C to +85°C) standard. All TEWS TECHNOLOGIES products feature a five-year warranty.

Extensive software support for major operating systems such as Windows, Linux, VxWorks, Integrity, and QNX is available.

Want early design analysis without simulation?

Sponsored by Siemens Digital Industries Software

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.
