Application Information

The TPMC460 is a standard single-width 32 bit PMC module and offers 16 channels of high performance asynchronous serial interface.

Five different standard modules are available: The TPMC460-10R provides 16 RS232 interfaces. The TPMC460-11R provides 16 RS422 interfaces. The TPMC460-12R provides 8 RS232 and 8 RS422 interfaces. The TPMC460-13R provides 12 RS232 and 4 RS422 interfaces. The TPMC460-14R provides 4 RS232 and 12 RS422 interfaces.

Other configurations are available as factory option on a per channel basis.

All modules offer front panel I/O with a HD68 connector and P14 I/O. Each RS232 channel supports RxD, TxD, RTS and CTS. Each RS422 supports RxD+/- and TxD+/-.

A transparent 32 bit / 66 MHz PCI-to-PCI Bridge provides access to the two Exar XR17D158 octal PCI-UARTs. The PCI-to-PCI Bridge allows 32 bit accesses on the local PCI bus and permits the high data throughput necessary for the high performance serial interfaces.

Each channel has 64 byte transmit and receive FIFOs to significantly reduce the overhead required to provide data to and get data from the transmitters and receivers. The FIFO trigger levels are programmable and the baud rate is individually programmable up to 921.6 kbps for RS232 channels and 5.5296 Mbps for RS422 channels. The UART offers readable FIFO levels.

Interrupts are supported. For fast interrupt source detection each octal UART provides a special Global Interrupt Source Register.

All serial channels use ESD protected transceivers up to ±15KV according to IEC 1000-4-2.

The TPMC460 can operate with 3.3V and 5.0V PCI I/O signaling voltage.

Software Support (TDRV002-SW-xx) for different operating systems is available.
