TCAN1145-Q1: SPI, daisy chain, parallel.

Part Number: TCAN1145-Q1


Hi~ Team.

TCAN1145-Q1 is SPI interface and does it support both parallel and daisy chain connection when use multiple devices?

Just example, when use two TCAN1145-Q1,

Parallel connection : need two SS(chip enable) for each device enable and share SCK, MOSI, MISO lines.

Daisy chain : MISO->next TCAN MISO connnection.

If can't use daisy chain, is there any reason?

Thanks.

    Hi Jin-Suk,

    TCAN1145 only supports multiple SPI devices with the use of multiple chip select signals (nCS). This device does not have the ability to repeat SPI data for a downstream device. 

    Let me know if you have any more questions.
