Data retention at an average junction
temperature of TJavg = 85°C after up to
10,000 program/erase cycles
1. Minimum times are based on maximum fNVMOP and maximum fNVMBUS
2. Typical times are based on typical fNVMOP and maximum fNVMBUS
3. Maximum times are based on typical fNVMOP and typical fNVMBUS plus aging
4. tcyc = 1 / fNVMBUS
Program and erase operations do not require any special power sources other than the
normal VDD supply. For more detailed information about program/erase operations, see
the Flash Memory Module section in the reference manual.
