Number of program/erase cycles.
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.
Parameters are valid over operating temperature range unless otherwise specified.
Typical ratings are not guaranteed. The values listed are at room temperature (25 °C), nominal supply
voltages.
