TPMC378 Conduction Cooled Serial Controller with 8 Insulated RS422 Interfaces

8 channel high performance serial controller with RS422 interfaces, each channel insulated from the system and against each other by digital isolator and onboard integrated DC/DC converter. The TPMC378 module is designed for the use on carrier boards with stiffener bars and has an operating temperature range of -40°C to +85°C.

Each RS422 channel supports RxD+/- and TxD+/-. Two channels additionally support flow control with RTS +/- and CTS +/-. All channels can operate in 4-wire full duplex mode. The modules have P14 I/O.

Each channel has 64 byte transmit and receive FIFOs. The FIFO trigger levels are programmable and the baud rate is individually programmable up to 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: Integrity, Linux, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.
