MEN Mikro Elektronik presents a new PMC module with four fast RS422/485 UART interfaces. The P507 is qualified for the extended temperature range of -40° to +85°C, and prepared for coating against dust and humidity, which makes it especially suited for safety-critical and mobile applications. Long-term availability until at least 2019 is guaranteed.

Fast, reliable and flexible

The P507 is a 32-bit/33MHz PMC module with four UARTs for fast serial data transfer. It supports full duplex (with RS422) and half duplex operation (with RS485). Each channel of this mezzanine module has its own 500V isolation, making it possible to realize transfer rates of up to 921,600bits/s. All ports are available on the 50-pin D-Sub front connector.

The UART functionality of the P507 is realized inside its on-board FPGA, which can be modified any time by implementing new IP cores in order to perfectly meet the customer’s requirements. Following the Universal Submodules (USM™) concept, the FPGA of the P507 is located on the main PMC; the line drivers are implemented on a sub-module, the USM.

The P507 can be used on any PMC-compliant host carrier board in any type of bus system independent of the application, i.e. CompactPCI®, VME or on any type of stand-alone SBC in telecommunication, industrial, medical, transportation or aerospace applications. Optionally, it is possible to equip the PMC with its own intelligence via a Nios® softcore. These features, combined with a long-term availability (at least ten years) and qualification for operation in the extended temperature range of -40° to +85°C, guarantee flexibility and future-safety for the user’s project.
