One Time Programmable Memory

The One Time Programmable Memory (OTP) is used to persistently store values determined during the

device calibration.

4.7.1 Memory Layout

The size of the OTP memory is 128 bit. 32 bits are used for the cryptographic signature. All remaining 96

bits go into the data protected by the signature. The OTP memory layout is detailed in Table 28.
