Symbol | Parameter | Min | Max | Unit |
---|---|---|---|---|
HOLD or NO HOLD Settings (NWE_HOLD ≠ 0, NWE_HOLD = 0) | ||||
SMC15 | Data Out Valid before NWE High | NWE_PULSE × tCPMCK - 4.6 | – | ns |
SMC16 | NWE Pulse Width | NWE_PULSE × tCPMCK - 0.3 | – | ns |
SMC17 | A0–A22 valid before NWE low | NWE_SETUP × tCPMCK - 4.2 | – | ns |
SMC18 | NCS low before NWE high | (NWE_SETUP - NCS_RD_SETUP + NWE_PULSE) × tCPMCK - 2.2 | – | ns |
HOLD Settings (NWE_HOLD ≠ 0) | ||||
SMC19 | NWE High to Data OUT, NBS0/A0 NBS1, NBS2/A1, NBS3, A2–A25 change | NWE_HOLD × tCPMCK - 3.9 | – | ns |
SMC20 | NWE High to NCS Inactive (1) | (NWE_HOLD - NCS_WR_HOLD) × tCPMCK - 3.6 | – | ns |
NO HOLD Settings (NWE_HOLD = 0) | ||||
SMC21 | NWE High to Data OUT, NBS0/A0 NBS1, NBS2/A1, NBS3, A2–A25, NCS change(1) | 1.5 | – | ns |
Note:
Hold length = total cycle duration - setup duration - pulse duration. “hold length” is for “NCS_WR_HOLD length” or “NWE_HOLD length”
