The UMCAN1057S 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 UMCAN1057S 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.
• Variants with a VIO pin allows for direct interfacing with 3.3 V and 5 V supplied microcontrollers.
The UMCAN1057S implements the CAN physical layer as defined in ISO 11898-2:2024 and SAE J2284-1 to SAE J2284-5. The UMCAN1057S includes CAN signal improvement capability (SIC), as defined in ISO 11898-2:2024 parameter set C. CAN signal improvement significantly reduces signal ringing in a network, allowing reliable CAN FD communication to function in larger topologies. In addition, the UMCAN1057S features a much tighter bit timing symmetry performance to enable CAN FD communication up to 8 Mbit/s. These features make the UMCAN1057S 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.
