OMI/OPAL (20295)

ON chip system for servo valve. The end user, STILL, one of the main European manufacturers for handling, provides requirements, conducts the experiments with the chip and provides the assessments. Formerly Thomson-CSF Services Industrie the designer and now Crouzet Automatismes the manufacturer of the servo-valve, specifies the on-chip system according to the end user requirements and the other application domains. To assess the design choices, it simulates the command/control algorithm on a VHDL model of the chip in its physical environment.
SGS-THOMSON Microelectronics studies the best trade-off for the combination of the digital and analog parts to design and realize the chip. It characterizes the microcontroller technology and the device. University of Genoa provides the VHDL model of the microcontroller. Silicon Systems Design studies the communication J1850 bus macrocell.

The availability of the studied component allows the reduction of the servo-valve size and target price for large quantities, to have access to the wide automotive market area and, to all the other market areas: handling, industrial, public works, avionics, to use a lower cost servo-valve.

The component can be used to control any DC motor up to 4 Amps.

The availibility of the J1850 bus macrocell allows to enter north American automotive market.

Achievements:

• The first version of the on-chip component is under test.
• The J1850 specification and VHDL model are produced.
