IO303

Configurable FPGA-based I/O module with 16 TTL and 24 RS422 I/O lines and Xilinx Virtex-II chip with 7k logic cells

This I/O module provides a total of 16 TTL and 24 RS422 I/O lines and is based on configurable FPGA technology (Xilinx Virtex-II with 7k logic cells) allowing Spedgoat to implement project specific functionality including:

  • Pulse train capture and generation:
    PWM, CAP (Capture), QAD (quadrature decoding)
  • Event-based interrupt, trigger, and inversion support
  • Protocols (SPI, I2C, ..)
  • Generic digital inputs and outputs
  • High-speed algorithmic subsystems (system design implementations)
  • Analog I/O with lowest latency and/or special synchronization schemes

By default (in price included) Speedgoat implements the following FPGA Code Modules:

3 x PWM (TTL), 3 x CAP (TTL), 3 x QAD (RS422), 1 x Interrupt (TTL), 1 x Inversor (TTL), and 14 x DIO (RS422).

An implementation different from the setup outlined above can be developed and provided at the time of the I/O module purchase or at a later time.

Note that each implemented FPGA Code Module reduces the no. of available I/O lines and logic cells, additional restrictions may apply:

Code
module 		Min./Max. no. of selectable code modules Required TTL OR RS422 lines per code module Required FPGA chip space per code module
PWM 2...m in steps of 2 3 (outputs - A, B, Trigger) 11%
CAP 2...n in steps of 2 1 (input) 6%
QAD 2...j in steps of 2 3 (inputs - A, B, Index) 11%
SPI 1...p in steps of 1 6 (master or slave) 10%
DIO 2...k in steps of 2 1 0%
Interrupt 1....q in steps of 1 2 4%
Inversor 1....r in steps of 1 2 1%

Formula to calculate the selectable code module mix and remaining FPGA space:
m x 3 + n x 1 + j x 3 + p x 6 + k x 2 + q x 2 + r x 2 <= 16 TTL/24RS422 lines and
m x 11% + n x 6% + j x 11% + p x 10% + q x 4% + r x 1% <= 100%.

If you require more code modules or logic cells have a look at the IO313. If you require I/O lines providing different transeiver types or even more logic cells have a look at the IO301-302, IO304, IO311-312, IO314, and 32x series.

Each IO303 I/O module comes with xPC Target driver blocks and Simulink test models, an external shielded 68-pin I/O cable and a terminal board for easy access of all physical I/O signals, and comprehensive documentation.

This I/O module in the PMC form factor and can be used in any Speedgoat real-time target machine with the exception of the Classic real-time target machine.

Contact Speedgoat to receive further information about this and other 3xx series I/O modules and to discuss your requirements.
