10. Dynamic characteristics
10.1 Flash/EEPROM memory
[1]
Number of program/erase cycles.
[2]
Programming times are given for writing 256 bytes from RAM to the flash. Data must be written to the flash
in blocks of 256 bytes.
10.2 External clock
[1]
Parameters are valid over operating temperature range unless otherwise specified.
[2]
Typical ratings are not guaranteed. The values listed are at room temperature (25
C), nominal supply
voltages.
