TXMC465 XMC Module with 8 Port Serial RS-232/422/485 Controller with Programmable Interfaces

XMC module offering 8 channel high performance serial controllers with individually programmable RS-232, RS-422, and RS-485 interfaces. The module has an operating temperature range of -40°C to +85°C.

RS-232 channels support RxD, TxD, RTS, and CTS, and RS-422 channels support RxD+/- and TxD+/-. RS-485 channels can operate in 4-wire full duplex or 2-wire half duplex mode. The module has front I/O via a HD50 connector.

Each channel has 256 byte transmit and receive FIFOs. The FIFO trigger thresholds, and the baud rates are individually programmable: up to 1 Mbps for RS-232 channels, and 10 Mbps for RS-422/485 channels. 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, LynxOS, Integrity, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.

The XMC module is also available as TPMC465 PMC module.
