TPMC371, TPMC372

TPMC371, TPMC372 Conduction Cooled 4 or 8 Port RS-232/422 Serial Interfaces

4 or 8 channel high performance serial interfaces with several standard combinations of RS232 and/or RS422 interfaces. The TPMC371 and TPMC372 conduction cooled PMC modules are designed for the use on carrier boards with stiffener bars and have an operating temperature range of -40°C to +85°C.

All RS232 channels support RxD, TxD, RTS, and CTS. Two channels of the TPMC371 and one channel of the TPMC372 have all signal lines for full modem support. All RS422 channels support RxD+/- and TxD+/-. Two channels of the TPMC371-11, and one channel of the TPMC372-11 offer also RTS+/- and CTS+/- signal lines. All modules have P14 I/O.

Each channel has 64 byte transmit and receive FIFOs. The FIFO trigger thresholds, and the baud rates are individually programmable: up to 921.6 kbps for RS232 channels, and 5.5296 Mbps for RS422 channels. All channels generate interrupts on PCI interrupt INTA. For fast interrupt source detection the UART provides a special global interrupt source register. All channels use transceivers with 15 KV ESD protection.

A wide range of drivers is available: Linux, Integrity, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.

Non-standard configurations are available as factory build option. The modules are also available as TPMC46X with convection cooling.
