1.3 Specification

TI offers the TCAN5102-Q1 CAN FDL Responder. The responder includes a single VDD supply supporting 3V to 5.5V, with I/O level shifting CAN transceivers.

The device is designed to support CAN FDL Responder node applications in a commander - responder architecture which does not require a responder node processor. All control for the responder node is through the CAN bus, from the commander node processor which eliminates the need for responder node processor and software. The TCAN5102-Q1 receives data and/or commands from a CAN FDL commander node which controls SPI, UART, or an I2C controller for communication to peripheral devices connected to the TCAN5102-Q1. The pins can be used as GPIOs if serial interfaces are not needed. Pulse width modulation (PWM) output channels also support trapezoidal ramp profiles in hardware for controlling stepper motors or PWM LEDs. Ramping of duty cycle or frequency is possible. No external crystal or clock is required.

The device controls the external 8-pin or 14-pin CAN FD transceivers (examples - TCAN844-Q1, TCAN1044A-Q1, TCAN1462-Q1, TCAN1162x-Q1, TCAN1043A-Q1 or TCAN1463A-Q1), for system level flexibility. The device relies 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.

The EVM is setup to help system designers evaluate the operation and performance of the TCAN5102-Q1 device with various peripherals communicating through I2C, PMW and GPIOs. Peripheral components are poupulated on the EVM. There are also populated headers that offer the flexibility to communicate with SPI, UART, or I2C to other peripherals off-board. The peripherals populated includes a U2 temperature sensor (TMP117 - controlled via I2C) and a RGB multi-color LED (LRTBVSR - controlled via GPIO and PWMs). The EVM also provides bus termination, bus filtering, and protection concepts. The EVM is easily configured by the users as needed by jumper settings, simple soldering tasks, and replacement of standard components.
