IMU Sensor BMI270 read back wrong ID 0x26 but not 0x24 (Chip Mark 5N 0KC)

[zhongying]

Hello we have read about SPI Bus Device ID from IMU Sensor BMI270. SPI works, but it read back an incorrect ID. According to Datasheet BMI270 we should read back ID 0x24. But we read back 0x26. Other customers also had this error: https://community.bosch-sensortec.com/t5/MEMS-sensors-forum/BMI270-wrong-chipID-response-0x26/m-p/51...  0x26 is ID of other component BIM220(Large customer component, no datasheet released!)

Our chip mark is 5N 0KC. 

My questions are:

1, according to chip id 0x26 we have got a BMI220 or BMI270?

2, Chip Marking 5n 0KC is for BMI270 or this is for BMI220?

Thank you

Hi zhongying,

 0x26 is the chip ID of BMI220. As you got 0x26 chip ID, where did you purchase the stock?

Thank you for your reply, We don't know where Sensors come from. We don't buy the chip. PCB Maker buy the chips.

You could confirm stock channel information(buy it from official distributor or not?) first if you would like to know more sensor information, zhongying.
