Software Data Protection
Enable Algorithm
(1)
Notes for software program code:
1.
Data Format: I/O7 - I/O0 (Hex);
Address Format: A14 - A0 (Hex).
2.
Write Protect state will be activated at end of
write even if no other data is loaded.
3.
Write Protect state will be deactivated at end of
write period even if no other data is loaded.
4.
1 to 64 bytes of data are loaded.
Software Data Protection
Disable Algorithm
(1)
Software Protected Write Cycle Waveforms
(1)(2)
Notes:
1. A6 through A14 must specify the same page address during each high to low transition of WE (or CE) after the software
code has been entered.
2. OE must be high only when WE and CE are both low.
