33390

Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33390/D Rev 4.0, 2/2003 33390 Class B Serial Transceiver The 33390 is a serial transceiver designed to provide bi-directional halfduplex communication meeting the automotive SAE Standard J-1850 Class B Data Communication Network Interface specification. It is designed to interface directly to on-board vehicle microcontrollers and serves to transmit and receive data on a single-wire bus at data rates of 10.4 kbps using Variable Pulse Width Modulation (VPWM). The 33390 operates directly from a vehicle's 12 V battery system and functions in a logic fashion as an I/O interface between the microcontroller's 5.0 V CMOS logic level swings and the required 0 V to 7.0 V waveshaped signal swings of the bus. The bus output driver is short circuit current limited. Features Designed for SAE J-1850 Class B Data Rates Full Operational Bus Dynamics Over a Supply Voltage of 9.0 to 16 V Ambient Operating Temperature of -40°C to 125°C Interfaces Directly to Standard 5.0 V CMOS Microcontroller BUS Pin Protected Against Shorts to Battery and Ground Thermal Shutdown with Hysteresis Voltage Waveshaping of Bus Output Driver 40 V Max VBAT Capability J-1850 SERIAL TRANSCEIVER Freescale Semiconductor, Inc...
