NOTES:
1. Referenced to VCC1=4.5 to 5.5V, 3.0 to 3.6V at Topr = 0 to 60 °C (U3, U5) unless otherwise specified.
2. Program and Erase Endurance refers to the number of times a block erase can be performed.
If the program and erase endurance is 100, each block can be erased 100 times.
For example, if a 4 Kbytes block A is erased after writing 1 word data 2,048 times, each to a different address, this counts as
one program and erase endurance. Data cannot be written to the same address more than once without erasing the block.
(Rewrite prohibited)
3. Maximum number of E/W cycles for which operation is guaranteed.
4. Topr = -40 to 85 °C (U3) / -20 to 85 °C (U5).
