Aquison™ Data Acquisition Platform
Actual Size is 4.0" x 6.0"
The Acquison platform is a real time system used to acquire data from sensors and perform real time control or processing.
The system brings together several hardware disciplines onto one PC board. It incorporates multi-channel 16-bit serial A/D converter, high performance FPGA with 50,000 gates, popular full speed EZ USB microcontroller, and support for many expansion capabilities.
The Acquison platform can serve a variety of applications, ranging from data acquisition with a PDA or host PC, to remote embedded internet data collection and control systems.
Designed to support new product development, the system helps you focus on your own rocket science design additions, rather than reinventing the many Acquison platform features.
Expansion daughtercards may be developed to accommodate specific component or processing needs you may have, such as sensor interfaces, alternate A/D converters, DSP, etc. The Acquison can serve as a base platform to support your product development needs.
16-Bit A/D converter with 8 single ended or 4 differential inputs - up to 100KHz sampling FPGA for real time HW controlled acquisition, control, processing and expansion. 50K gates! Ethernet connectivity (optional) supporting internet web access with a powerful Rabbit 2000 processor. USB Controller for Full Speed operation - includes a fast microcontroller for your application. Two expansion daughtercards supported to accommodate your interface and custom needs.
Motivations for using the Acquison platform:
Why re-invent another data acquisition system ?
Save money and time using the Acquison expandable platform.
Avoid costly PC cards and inflexible development software
Prove your next product concept faster by using the Acquison.
Leverage Acquison schematics for your production design phase
This is a "One Size Fits Many" platform.
Markets: Medical, Industrial and Commercial
Serves as a development platform for sensor applications which benefit from USB or Ethernet connectivity. Medical - cardiology and pulmonary applications, home monitoring products or any product development which utilizes sensors. Industrial - production sensor acquisition and control interfaces, from flow sensors to robotic acquisition and control systems, telephony systems or even protocol analyzers.
Commercial - PDA enabled or remote internet acquisition and controls.
Feature Details System Single supply operation off the USB connector, or use multiple supplies with the auxiliary power input connector Ethernet and/or USB connectivity plus one RS232 port Add custom daughtercards for your custom interface needs Analog Analog Input range of 0 to 4V for all 8 channel 2V and 4V references to daughtercards Digital Expansion connector provides 32 FPGA I/O pins and 3.3V power for daughtercard. FPGA I/O pins are 5V tolerant. Analog Expansion connector for up to 8 analog inputs provides clean +4.5V for analog circuitry plus alternate power signals.
Digital FPGA program may reside in onboard PROM, or be downloaded from the USB host, the RabbitCore, or even over the ethernet connection!! FPGA used is the footprint accepts Spartan II devices with 15,000 to 100,000 gates (50K gates standard)
Xilinx and IP core developers provide digital building blocks and FPGA building blocks so you don't have to reinvent the wheel.
A serial EEPROM is dedicated to the FPGA for your use - perhaps to hold calibration constants? Ethernet RabbitCore RCM2200 module utilized Rabbit 2000 (Z180 derivative) processor, for embedded internet 256K Flash, 128K SRAM, 4 serial ports, TCP/IP, UDP, email, web serving are all viable applications Royalty-free TCP/IP stack with source with development SW Acquison FPGA may be loaded from the RabbitCore module Built-in 10Base-T port with RJ-45 jack for LAN or Internet connectivity USB EZ-USB compliant with USB v1.1 specification Supports isochronous, bulk, control, and interrupt data 31 end points - all can be double buffered 8K SRAM internal and 32K SRAM onboard I²C controller and serial EEPROM for configuration Expansion One or two daughtercards supported Separate digital and analog connectors with separate power too 28 FPGA I/O lines to be assigned per your custom FPGA design USB I²C and FPGA I²C serial I/O available for daughtercard use 2V, 4V references and auxiliary power available to daughtercards
