The TPMC372 is a conduction cooled single-width 32 bit PMC module and offers 4 channels of high performance asynchronous serial interface.
Three different standard modules are available: The TPMC372-10xR provides 4 RS232 interfaces. The TPMC372-11xR provides 4 RS422 interfaces. The TPMC372-12xR provides 2 RS232 and 2 RS422 interfaces.
Other configurations are available as factory build option on a per channel base.
All modules offer P14 I/O. Each RS232 channel supports RxD, TxD, RTS, CTS and GND. Each RS422 channel supports RxD+/-, TxD+/- and GND. One channel of the TPMC372-10xR/-12xR offers full modem support (TxD, RxD, CTS, RTS, DSR, DTR, CD, RI and GND) for RS232. One channel of the TPMC372-11xR supports RxD+/-, TxD+/-, RTS+/-, CTS+/- and GND for RS422.
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.
All channels generate interrupts on PCI interrupt INTA. For fast interrupt source detection the UART provides a special Global Interrupt Source Register.
All serial channels use ESD protected transceivers. ESD protection is up to ±15KV.
The TPMC372 can operate with 3.3V and 5.0V PCI I/O signaling voltage.
Software Support (TDRV002-SW-xx) for different operating systems is available.
