Hello,
I'd like to know what are the SL3S40X1 capabilities for user memory protection. After reading the datasheet, I still have following questions:
- After activation of the read protection, the user memory cannot be read via: RF, I2C or both?
- How could this read protection be disabled?
Thanks in advance
When read protect is enabled the IC will only allow this information to be read when in the “secured” state. However, the I²C interface always has this “secured” privilege. Please check this in section 12 RF interface/I2C interface arbitration.
"I2C access to the chip memory is possible regardless if it is in the EPC Gen2 secured
state or not"
This means that whenever you need to disable the UCODE memory protection you can do this securely by I2C.
