TLE9251VLEXUMA1

Introduction

TLE9251VLEXUMA1 is an integrated transceiver SPI bus interface device with a 9-bit dynamic CAN bus node interface. It combines an integrated CAN transceiver with a complete CAN controller interface and provides a flexible, cost effective solution for vehicle connectivity systems. The TLE9251VLEXUMA1 includes integrated power management and software configurable CAN bit timing, allowing it to be adaptable to a variety of CAN protocols.

Application Field

The TLE9251VLEXUMA1 is designed for applications requiring low power and fast communication. Its low power operation and flexible bit-rate configuration make it ideal for automotive applications. It is designed for use in vehicles with SPI or UART busses, providing a reliable and efficient communication interface between devices. Additionally, the TLE9251VLEXUMA1 can be used for communication with a variety of CAN devices, including those requiring CAN FD, CAN 2.0A, CAN 2.0B, ISO 11898-2, ISO 11898-3, and ISO 11898-5 protocol support.

Working Principle

The TLE9251VLEXUMA1 consists of two components. The first is the integrated CAN transceiver, which features an edge detector to detect activity on the bus and a 9-bit data register to store received data. The second component is a complete CAN controller interface, which features an SPI bus interface, up to 64-byte message buffers and a software configurable 9-bit dynamic CAN bus node address.

The TLE9251VLEXUMA1 is powered by a 3.3V supply and can be used in applications ranging from battery powered, automotive applications to high power industrial applications. The device is powered directly by the vehicle and is capable of providing wake-up capabilities, allowing the device to remain in a low power state when not actively communicating. Additionally, the TLE9251VLEXUMA1 supports up to eight transmit and eight receiver buffers, allowing for reliable communication.

The TLE9251VLEXUMA1 is an economical and efficient solution for vehicle connectivity systems. With its integrated power management and software configurable CAN bit timing, the TLE9251VLEXUMA1 provides a reliable and cost-effective way to connect CAN devices while reducing overall system cost.
