Overview


The CS-MiniDSP controller board is the second-generation main processor board of the MINI MICRO card series. It is a low cost, high performance DSP based controller, intended specifically for applications where a discrete BUS based system would be too expensive, and where time/money/resource constraints make a custom design impracticable. The card is designed around a Texas Instruments TMS320F240 DSP chip, which has been specifically optimised for use in digital motor/motion control applications, running from a 20MHz clock oscillator.

The CS-MiniDSP has 8 major sections:

  • TMS320F240 DSP processor
  • on-card memory
  • MINI BUS interface
  • Analog Inputs
  • PWM outputs
  • Digital I/O
  • Communications
  • ancillary support circuitry.

There are two configurations available of the card;

  • Standard version, which is designed to be a standalone DSP-based controller, and
  • Plug-in version, which is designed to plug into a custom-designed motherboard.
The standard card is powered from unregulated ±18V DC supplies, and generates all necessary regulated voltages on-card. The plug-in card requires regulated +/-15V and 5V supplies to be provided from off-card

Technical Specifications

  • Designed around a Texas Instruments TMS320F240 DSP chip
  • Available as a plug-in daughterboard to a custom motherboard.
  • Requires off-card regulated +/-15V and 5V supplies.
  • Optional On-card supply regulation.
  • Altium/Protel footprint available

 

On-card facilities include:

  • A socket for a 64k x 16 EPROM
  • 128k x 16bit RAM, arranged as

    •     - 64k x 16bit program RAM
        - 32k x 16bit external data RAM
  • Power-fail circuitry

 

The card also has the following peripheral interfaces:

  • RS-232 serial interface
  • 3 wire clocked serial port (SPI master)
  • 1 off 16-bit TTL digital I/O, (2 off 8 bit I/O banks)
  • 16 off single ended analog inputs (+/-10V input)
  • 8 bit MINI bus interface (INTEL iSBX compatible)
  • 4 bit TTL digital input / external interrupt port
  • 8 PWM outputs, (3 off complementary pairs and 2 off independent outputs
  • On-card voltage regulation - analog voltage reference

Dimensions:
