5/3/2023 0 Comments Tpl vs dplCS1\ being asserted by the MCU causes a start of message double positive pulse on the TPL bus. At the top of the waveforms, the MCU is going to initiate a command to the MC33771. The picture below illustrates how the MC33664 TPL transceiver exchanges data between the MCU and the MC33771.įirst, you can notice that the MCU needs two SPI ports for the SPI to TPL translation one for MOSI and one for MISO. better communication speeds and synchronized measurements.more robust Electromagnetic Compatibility (EMC) characteristics (intrinsic transformer.High-speed differential isolated communication is achieved through the use of transformers. The MC33771/MC33772 (battery cell controller) and MC33664 (TPL transceiver) communication solution is based on a passive electrical bus (no repeater, no amplifier). TPL stands for transformer physical layer.
