Notes: 1. Commands not interpreted in this table will default to read array mode.
2. A wait of tPLYH is necessary after a Read/Reset command if the memory was in an Erase or Program mode
before starting any new operation.
3. X = Don’t Care.
4. The first cycles of the RD or AS instructions are followed by read operations. Any number of read cycles can occur after
the command cycles.
5. Signature Address bits A0, A1 at VIL will output Manufacturer code (20h). Address bits A0 at VIH and A1 at VIL will output
Device code.
6. Block Protection Address: A0 at VIL, A1 at VIH and A12-A16 within the Block will output the Block Protection status.
7. For Coded cycles address inputs A15 and A16 are don’t care.
8. Optional, additional Blocks addresses must be entered within the erase timeout delay after last write entry,
timeout status can be verified through DQ3 value (see Erase Timer Bit DQ3 description).
When full command is entered, read Data Polling or Toggle bit until Erase is completed or suspended.
9. Read Data Polling, Toggle bits or RB until Erase completes.
10.During Erase Suspend, Read and Data Program functions are allowed in blocks not being erased.
