DATA SHEET

The SIGNALWARE AED-103 Multi-Channel Analog Expansion Daughterboard for the Texas Instruments TMS320C5x/C6x Evaluation Module provides an economical way of building a process control interface. The daughterboard has two 8-channel A/D converters and two D/A converters that can monitor the process sensor outputs and produce analog signals to control the process. In addition to the analog channels, three groups of 8 buffered digital signals can be switched to either input or output. Breadboard space is provided for constructing signal conditioning and interface circuits. This daughter board has application in mass storage, automotive, digital services, image sensor processing, and other process control services.

The AED-103 is ideally suited to prototyping custom process control units based on the TI C6x Digital Signal Processor (DSP). Hybrid (digital and analog) circuit prototyping is conveniently accomplished with this daughterboard. Also, the AED-103 may be used to construct inexpensive personal computer based process control units where the number of systems does not justify a custom designed printed circuit board. The AED-103 is an excellent DSP analog interface for many other multiple input/output applications.

The standard AED-103 consists of a daughterboard for the expansion interface on the C6x Evaluation Module. The full size daughter board configuration includes 2-A/D, 2-D/A, voltage reference, digital buffers, amplifiers, regulators, programmable logic interface, and 90 pins on I/O connectors for off-board connections. The AED-103 comes with a demonstration logic program and software for the C6x DSP.

Programmable DSP I/F Adds Performance

Preprocessing of the A/D samples and control of the converters with the Field Programmable Gate Array (FPGA) significantly reduces the load on the DSP making more computation possible with a single C6xxx DSP. A Xilinx SPARTAN^TM XCS20XL FPGA with 20,000 logic gates (1120 flip-flops, 12K RAM bits) is standard, and larger FPGAs are available as options. Serial flash memory (optional), socketed PROM or the JTAG port can provide FPGA configuration.

Surface Mount Breadboard Adds Flexibility

To make the analog interface to the board convenient and flexible, 7 sq. in. of breadboard space is provided. The analog interface to the A/D and D/A converters always needs to be tailored to the application. No approach is more flexible than a breadboard area specifically designed for surface mount and through-hole analog ICs. The AED-103 breadboard accommodates wide and narrow SOICs (50 mil pitch) as well as 0.3 and 0.6 DIPs (100 mil pitch). By keeping the signal conditioning circuits on the board with the converters, noise, errors, and cost are reduced. All 16 analog input buffer amplifiers have flexible configurations with inputs adjacent to the breadboard area. The 2 analog output buffer amplifier outputs are available to the breadboard area. Regulated +/- DC analog power buses supply the breadboard area.

Flash Memory Adds Stand-alone Capability

The AED-103 has optional flash memory for C6x program and data storage. Lack of boot up memory is often the critical factor in using the EVM in stand-alone mode. Either a 512 Kbyte or 1 Mbyte option is available.
