Notes:

1. Minimum VDD supply voltage without losing data stored in RAM (in STOP mode or under RESET) or in hardware reg-

isters (only in STOP mode). Guaranteed by construction, not tested in production.

2. Data based on reliability test results and monitored in production. For OTP devices, data retention and programmability

must be guaranteed by a screening procedure. Refer to Application Note AN886.

3. The data retention time increases when the TA decreases, see Figure 49.
