the new mc302x:
single board controller.
- new improved power supply:
no electrolytic caps.
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.
