Full mPCIe module packs user programmable FPGA

Article By : Tews Technologies

The TMPE633 from Tews Technologies is aimed at industrial, COTS and transportation applications, where specialised I/O or long-term availability is required.

Tews Technologies has released what it describes as a standard full PCI Express Mini Card with a user programmable Xilinx Spartan-6 LX25T FPGA. According to the company, the TMPE633 is aimed at industrial, COTS and transportation applications, where specialised I/O or long-term availability is required.

The TMPE633 provides various advantages including a customisable interface for unique customer applications. An FPGA-based design for long-term product lifecycle management module versions are available with either 26 ESD-protected 5V-tolerant TTL lines, 13 differential I/O lines with EIA 422/485 compatible ESD-protected line transceivers or 13 differential I/O lines using Multipoint-LVDS transceivers, detailed the company.

All I/O lines are individually programmable as input or output. TTL I/O lines can be set to high, low or tristate. Each TTL I/O line has a pull-resistor to a common programmable pull-up voltage that can be set to 3.3V, 5V and GND. Differential I/O lines are terminated, RS-485 lines with 120Ω and M-LVDS lines with 100Ω. The I/O signals are accessible through a 30 pin Pico-Clasp latching connector.

The user FPGA is configured by a SPI flash. An in-circuit debugging option is available via a JTAG header for read back and real-time debugging of the FPGA design. The TA308 Programming Kit allows direct JTAG to have access to the FPGA using the Xilinx Platform Cable USB. User applications for the TMPE633 with XC6SLX25T-2 FPGA can be developed using the design software ISE WebPACK that can be downloaded free of charge from www.xilinx.com.

In order to support long term programmes, the modules have a five-year warranty.
