- 4 high-performance UARTs, compatible to 16550 UART
- FIFO buffer
- Serial data rate up to 2 Mbit/s
- Full and half duplex on 4 channels
- 500 V AC optical isolation
- -40°C to +85°C with qualified components
The M-Module M77N has been developed according to the ANSI Mezzanine standard and extends the carrier board by four electrically isolated serial interfaces, which can be adapted to the respective requirements by software.
Robust and reliable system extension in the ANSI standard
The M-Module M77N supports four high-performance UARTs with RS232 or RS422 / 485 interfaces – implemented in the FPGA. These are accessible via a D-Sub connector at the front and can be connected to the carrier card, and thus to the backplane of the system via a 24-pin onboard connection, if required. The interface mode of the M-Module can be changed by software.
The serial lines have been optically isolated, which is essential for use in automotive or industrial applications as well as in mobile environments, for example, to protect the control system from external disturbances such as high voltage pulses.
All components of the M77N are firmly soldered against shock and vibration, and are approved for a temperature range of -40°C to +85°C.
M-Modules – an ANSI-VITA standard since 1997 – are ideally suited for the connection of binary and analog process I/O, robotics, motion and measurement functions. As an extension to all common bus systems such as CompactPCI, ComapctPCI Serial, VMEbus or independent SBCs, mezzanine modules complement each application in a tailor-made and modular manner.
