CAN FD Light Responder to SPI/UART/I2C/GPIO Controller

The TCAN5102-Q1 is a Control Area Network (CAN) Flexible Data (FD) Light

responder device compatible with CiA 604-1 and ISO 11898-1:2024, capable of

supporting up to 5Mbps data rate when a dedicated CAN FD light commander is used.

The device is designed to support CAN FD light responder node applications in a

commander - responder architecture which does not require a responder node

processor. All control to the responder node is through the CAN bus from the

commander node processor which eliminates the need for responder node processor and

software.

The device receives data and/or

commands from a CAN FD light commander node which translates these to either Serial

Peripheral Interface (SPI) controller, UART controller, I2C controller,

and/or GPIO pins communication to the device and/or peripheral devices the TCAN5102-Q1 is controlling. PWM output channels also

support trapezoidal ramp profiles in hardware for controlling stepper motors.

Ramping of duty cycle or frequency is possible. No external crystal or clock is

required. The device controls the external TCAN1162x-Q1, TCAN1043A-Q1 or

TCAN1463A-Q1 CAN FD (SIC) transceivers for system level flexibility. The device

relys upon the CAN FD transceiver/SBC to control the node power and communicate a

wake up signal to the TCAN5102-Q1 by latching the CAN

RXD (CRXD) pin low.
