Aitech C437 - ARINC-429 A/D, D/A and Digital I/O VME Board

4 Opto-isolated Inputs & Outputs, 16 ARINC-429 Inputs, Eight ARINC-429 Outputs and more

Introduction

Aitech's C437 provides multiple I/O including ARINC-429, Analog to Digital, Digital to Analog, and discretes, as well as an MP3 player with stereo audio output, on a single slot rugged VME board. The card integrates a sophisticated design totally separating it into independent analog, digital, and discrete domains, thereby minimizing crosstalk and interference, allowing it to achieve high quality analog to digital and digital to analog conversions.

With its extensive I/O capabilities, the C437 provides an attractive solution for system integrators requiring I/O for large numbers of sensors and actuators as in avionics and other versatile control systems. Analog inputs and outputs can be factory configured for compatibility with a wide range of devices. Also provided is an Audio Announcement System with stereo audio output for systems that provide audiomessages playback. Dedicated Flash and SRAM resources enable the C437 to play pre-recorded audio messages in various formats (mp3, wav, etc.) as well as run time messages. 

With its exceptionally low power consumption per functionality, the C437 can easily be integrated into systems having moderately sized power supplies. System thermal design is also simplified by the low power consumption.

The VMEbus interface implemented in the C437 is incorporated in an FPGA logic device providing simple and reliable interface. The VME interface provides slave functionality only and supports A32/D08/D16/D32 access modes.

The FPGA also provides full autonomous control over all onboard functions, leaving the VME host board free to perform other tasks.

The C437 is delivered with a complete set of drivers and Built-In Tests (BIT) for all on board resources. The drivers integrated into the VME host card environment provide full control/status and access to all of
the C437 modules.

The C431 is optionally delivered with a complete set of drivers and optional Built-In Tests (BIT) for all of its on board resources. The drivers integrated into the VME host card environment provide full control and access to all of the C431 modules. The on-board temperature sensor enables fixing of analog and digital conversion errors.

General

ExpansionThe C437 VME Bridge is implemented in an FPGA logic device. The VME Bridge provides slave VME capabilities and supports A32/D08/D16/D32 data
transfers from/to any standard VME host board the C437 supports VMEbus interrupts generation on any of the seven VME interrupt levels.
ElectricalIn its default configuration, the C437 receives all its power from the VME backplane +5.0 V, +12 V, and - 12 V supplies. It can also be configured at the factory to utilize the +3.3 V power supply from the backplane supply as defined in the VME64x specification.
Typical power consumption of the fully featured C437 is 14 W, as follows:
+5.0 V @ 0.4 A
+3.3 V @ 0 A
+12 V @ 0.5 A
?12 V @ 0.5 A
