Texas Instruments
CAN FD Controller 20-VQFN (3.5x4.5)
NRND3,059 in stock

Overview

The TCAN4550RGYRQ1 is a highly integrated System Basis Chip (SBC) that combines a CAN FD controller, a CAN FD transceiver, and an internal LDO regulator into a single package. It allows microcontrollers without a native CAN FD peripheral to communicate over a high-speed vehicle network via a standard SPI interface at clock speeds up to 18 MHz.

Why Choose This Part

The device features integrated plus/minus 58 V bus fault protection and a built-in LDO providing up to 70 mA of external current, reducing the need for external power components. It supports high-speed data rates up to 8 Mbps and includes a low-power sleep mode with a typical current consumption of 42 uA.

Applications

Automotive Body Electronics
Ideal for lighting control, gateway modules, and door electronics where CAN FD bandwidth is required but the local MCU lacks integrated support.
Industrial Automation
Enables high-speed industrial communication in motor controllers and sensor nodes using Bosch M_CAN protocol architecture.
Safety-Critical Systems
Suitable for functional safety quality-managed applications requiring AEC-Q100 qualification and robust fault protection.

Getting Started

Engineers can evaluate the device using the TCAN4550EVM evaluation module from Texas Instruments. Implementation requires configuring the internal 2 KB RAM for message buffers and interfacing with the host processor via the SPI bus using the provided Bosch M_CAN register set.
