BQ78350-R1: Lifetime Data Block 3 - Data Order

Part Number: BQ78350-R1
Other Parts Discussed in Thread: BQSTUDIO

Hi all

I read the all Lifetime Data Blocks from BQ78350-R1 via a host MCU , also checked using BQStudio. Everything is OK.

Only Lifetime Datablock 3 data order(last 4 values) does not match with the bq78350-R1 Technical Reference manual's order. 

                                

     

                                        My Reading                          BQStudio

MAX Cell Temperature,          25                                          40

MIN Cell Temperature,           40                                          25

MAX Delta Cell Temp           -128                                         15

MAX FET Temperature           15                                        -128

Is this just a Technical Manual mistake ? Any Suggestions ? 

BR,

    Hi Çağdaş,

    I checked the data manual and everything appears to be correct and match the data flash order of the device. When you do block reads from ManufacturerAccess, keep in mind that all readings are Little Endian.

    From the TRM: "For example, a 2-byte data 0x1234 should be read/write as 0x34 + 0x12; a 4-byte 0x12345678 data should be read/write as 0x78+ 0x56+ 0x34 + 0x12." 

    Best regards,

    Matt
