Legend : L = VIL, H = VIH, X = VIL or VIH. See “DC CHARACTERISTICS” for voltage levels.
Notes:
1. Other operations except for indicated this column are prohibited.
2. Do not apply CEf = VIL, CE1r = VIL and CE2r = VIH all at once.
3. PSRAM Output Disable condition should not be kept longer than 1ms.
4. WE can be VIL if OE is VIL, OE at VIH initiates the write operations.
5. PSRAM LB,UB control at Read operation is not supported.
6. It is also used for the extended sector group protections.
7. The PSRAM Power Down Program can be performed one time after compliance of Power-UP timings and it should not be re-
8. PSRAM Power Down mode can be entered from Standby state and all DQ pins are in High-Z state. IPDr current and data retention
9. Either or both LB and UB must be Low for PSRAM Read Operation.
10. Can be either VIL or VIH but must be valid before Read or Write.
11. See “ PSRAM Power Down Program Key Table “ located in the next page.
12. Protect “ outer most “ 2x8K bytes ( 4 words ) on both ends of the boot block sectors.
