16 kbit EEPROM
1 RS-232 and 1 LIN serial interface
2 CAN, 125 to 500 kbit/s
A variety of analog and digital I/O
Internal monitoring of board temperature and sensor supply and battery voltages
An injection molded aluminum housing, with splash-proof connectors, pressure adjusting water barriers, and cooling fins
SFX 2000 specifications add to these:
