Hello! Please tell me whether an MC33774A driver is available for the MC33664ATL1EG iso-spi communication with STM32?
THX!
Hello Edzus,
We can provide the MC33774A software driver as part of our BMS SDK.
For the MC33664ATL1EG, it is a physical-layer transceiver converting the MCU’s SPI bitstream to/from the isolated bus and back to SPI. There is typically no separate high-level “driver” beyond configuring the MCU SPI interfaces and generating the correct frames.
Please note that MC33664 uses a dual-SPI architecture (separate TX SPI and RX SPI pins). On STM32 this usually requires two SPI peripherals (TX as master, RX as slave) or an equivalent implementation.
BRs, Tomas
Dual SPI
