the new mc302x:

jan 2006

• new improved pcb layout:

single board controller.

• new improved power supply:

no electrolytic caps.

• new fpga:

smaller.

• new improved application memory 4mbit (apps ram).

• new memory arrangement, arm7 based processor with internal flash memory of 16 mbit

• new improved encoder/stepper transceiver with new esd protection devices allowing a better esd protection.

• connection to encoder and/or stepper axis via 2 d-type connector like on the mc206x.

• possibility to use axis0 as stepper encoder and axis1 as stepper only or axis1 as stepper encoder and axis0 as servo/encoder. (see d-type pin desc-ription).

• new can controller, 3.3v oki can controller ml9620.

• new dac isolation using icoupler technology.

• new improved rs485 transceiver, better esd protection and voltage threshold.

• two serial connector, one minidin connector for rs232 port#0, on other one for port#1 rs232 or rs485. (see serial connectors pin connection)

• new wdog circuitry using a single solid state relay.

• new improved clock generator circuitry, smaller surface mount xtal and better spread spectrum device.

• new output drivers, quad channel high side driver.

• new atype 46 to use as  a stepper encoder with external encoder input.

• atype 4 use as a stepper encoder with internal encoder loop back as for mc206.

axis pin desc-ription:

standard atype:

atype axis(0)=46 (stepper encoder type with external encoder input )

atype axis(1)=46 (stepper encoder type with external encoder input )
