Freescale Semiconductor Advance Information High Speed CAN Interface with Embedded V Supply 33902 The MC33902 is a high speed CAN physical interface. The device includes an internal V supply for the CAN bus transceiver, and requires only a connection to a battery line. The MC33902 provides 4 operation modes, including low power modes with remote and local wake-up. The device has very low sleep and standby current consumption. • High speed CAN interface for baud rates of 40 kb/s to Mb/s • Compatible to ISO11898 standard • Single supply from battery. No need for a V supply for CAN interface • I/O compatible from V to V via a dedicated input terminal V or V logic compatible • Low Power mode with remote CAN wake-up and local wake-up recognition and reporting • CAN bus failure diagnostics and TXD/RXD pin monitoring, cold start detection, wake-up sources reported through the ERR pin • Enhanced diagnostics for bus, TXD, RXD and supply pins available through Pseudo SPI via existing terminals EN, STBY and ERR. • Split terminal for bus recessive level stabilization • INH output to control external voltage regulator • Pb-free packaging designated by suffix code EF HIGH SPEED CAN PHYSICAL INTERFACE EF SUFFIX PB-FREE 98ASB42565B 14-PIN SOICN ORDERING INFORMATION Device MCZ33902EF/R2 Temperature Range TA -40°C to 125°C Package 14 SOIC VBAT INH Voltage Regulator VDD I/O Controller 33902 WAKE INH VSUP GND 5V Reg STBY EN ERR TXD RXD I/O & Control Bus Diag.
