TEWS TECHNOLOGIES Introduces High Density Isolated RS422 PMC Module
Eletter Product
TEWS TECHNOLOGIES extends its tradition of delivering high-density I/O solutions with its introduction of the TPMC378 high-density isolated serial communication controller. The conduction cooled single-width 32-bit PMC module is ideal for applications in transportation, COTS, communications, and process control.
The TPMC378 can operate with 3.3V and 5.0V PCI I/O signaling voltage. It provides 8 channels of high performance RS422 asynchronous serial interface with P14 I/O. Each of the serial channels is isolated from the system and against each other by isolated transceivers with integrated DC/DC converters.
Each RS422 channel supports a four wire interface (RX+, RX-, TX+, TX-) plus ground (GND). Two channels additionally support flow control with RTS+/- and CTS+/-.
All channels generate interrupts on PCI interrupt INTA. For fast interrupt source detection the UART provides a special Global Interrupt Source Register.
Each serial channel of the PMC module has separate 64 byte receive and transmit FIFOs to significantly reduce the processing overhead required to provide data to and from the transmitters and receivers. The FIFO trigger levels are programmable, and the baud rate is individually selectable up to 5.5296 Mbps for RS422 channels. The UART offers readable FIFO levels.
All serial channels use ESD protected transceivers. ESD protection is up to ±15KV.
The TPMC378 offers an operating temperature range of -40°C to +85°C. All TEWS TECHNOLOGIES products feature a five-year warranty.
Extensive software support for major operating systems such as Windows, Linux, LynxOS, VxWorks, Integrity and QNX is available.
