11.6 MEMORY CHARACTERISTICS
Subject to general operating conditions for VDD, fOSC, and TA unless otherwise specified.
11.6.1 RAM and Hardware Registers
11.6.2 EPROM Program Memory
Figure 55. EPROM Retention Time vs. Temperature
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 55.
