TPMC377 Conduction Cooled Serial Controller with 4 Insulated RS232/422/485 Ports with Programmable Interfaces

4 channel high performance serial controller with individually programmable RS232, RS422, and RS485 interfaces. Each of the four channels are insulated from the system and against each other by digital isolator and onboard integrated DC/DC converter. The conduction-cooled PMC module is designed for the use on carrier boards with stiffener bars and has an operating temperature range of -40°C to +85°C.

RS232 channels support RxD, TxD, RTS, and CTS, and RS422 channels support RxD+/- and TxD+/-. RS485 channels can operate in 4-wire full duplex or 2-wire half duplex mode. The TPMC377 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 RS422/485 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.
