Key Specifications
Product Description The UMCAN1057 is a high-speed CAN transceiver that provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed CAN applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The UMCAN1057 offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features:
• Ideal passive behavior to the CAN bus when the supply voltage is off. • UMCAN1057VS8 and UMCAN1057VDA can be interfaced directly to microcontrollers with 3.3V or 5V supply voltage. The UMCAN1057 implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s. These features make the UMCAN1057 an excellent choice for all types of HS-CAN networks, in nodes that do not require a standby mode with wake-up capability via the bus. Features
- ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant
- Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase
- Suitable for 12V system
- VIO input on UMCAN1057VS8 and UMCAN1057VDA allows for direct interfacing with 3.3V or 5V microcontrollers
(available in SOP8 and very small DFN8 packages respectively) - EN input on UMCAN1057ES8 allows the microcontroller to switch the transceiver to a very low-current Off mode
- Transceiver disengages from the bus when not powered up (zero load)
- High ElectroStatic Discharge (ESD) handling capability on the bus pins
- Transmit Data (TXD) dominant time-out function
- Undervoltage detection on pins VCC and VIO
- Thermally protectedPin Configuration
