10. Dynamic characteristics
10.1 Power-up ramp conditions
[1]
[2]
The wait time specifies the time the power supply must be at levels below 400 mV before ramping up.
10.2 Flash 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.
