Micromech is pleased to introduce the Motionnet chip set from Nippon Pulse the G900x series that provide the capability of serial communication.

First in the series is the G9001 a 64-pin QFP and is known as the centre device, it has 256-bytes of RAM available for I/O and 512-bytes of RAM for motion control and data communication. It can control up to a maximum of 64 local devices; maximum communication speed of 20Mbps and it uses RS485 communication.

The G9002 and G9003 serve as the local devices that can connect to the G9001. It can connect up to 64 pieces of the G9002 (I/O device), 64 pieces of the G9003 (motion device), or any combination of the two (not to exceed 64 pieces total). The G9002 is an I/O device that has four 8-bit ports per device, is an 80-pin QFP, and uses cyclic transfer. The G9003 is an 80-pin QFP for use as a single axis motion device that outputs 5Mpps to control stepper or servomotors. It also offers various motion profiles, an encoder signal interface, and the ability to change speed and position on the fly.

The G9004 is an 80-pin QFP for use as a CPU emulation device that can operate in either CPU emulation mode or message communication mode. When in CPU emulation mode it outputs signals identical to those from CPU terminals and uses data from the G9001. In message communication mode it communicates freely with any CPU connected to the G9001 and itself. The chip can control various types of CPU, communicate in 256 byte (maximum) groups, and has both 8-bit and 16-bit CPU interfaces.

Ideal applications for the Motionnet Series would be factory automation, biomedical machines, and semiconductor equipment
