Document Number: MC33897 Freescale Semiconductor Rev. 18.0, 4/2012 Technical Data Single Wire CAN Transceiver 33897 The 33897 series provides a physical layer for digital communication using a Carrier Sense Multiple Access/Collision Resolution (CSMA/CR) data link operating over a single wire medium. This is more commonly referred to as single-wire Controller Area SINGLE-WIRE CAN Network (SWCAN). TRANSCEIVER The 33897 series operates directly from a vehicle s 12 V battery system or a broad range of DC-power sources. It can operate at low or high (33.33 kbps or 83.33 kbps) data rates. A high-voltage wake-up feature allows the device to control the regulator used in support of the MCU and other logic. The device includes a control pin that can be used to put the module regulator into Sleep mode. The presence of a defined wake-up voltage level on the bus will reactivate the control line to turn the regulator and the system back ON. EF (PB-FREE) SUFFIX The device complies with the GMW3089v2.4 General Motors 98ASB42565B Corporation specification. 14-PIN SOICN Features ORDERING INFORMATION Waveshaping for low Electromagnetic Interference (EMI) Detects and automatically handles loss of ground Temperature Device Package Worst-case Sleep mode current of only 60 A Range (T ) A Current limit prevents damage due to bus shorts MCZ33897TEF/R2 Built-in thermal shutdown on bus output -40 to 125 C 14 SOICN *MC33897CTEF/R2 Protected against vehicular electrical transients Under-voltage lockout prevents false data with low battery *Recommended device for all new designs Power source Voltage Battery Regulator EN 33897 VBATT CNTL V CC TXD MCU BUS SWC Bus RXD MODE 0 LOAD MODE 1 GND 4 Figure 1. 33897 Simplified Application Diagram Freescale Semiconductor, Inc. reserves the right to change the detail specifications, as may be required, to permit improvements in the design of its products.
