43 / 102 page ![]() November 2007 Datasheet Order Number: 290701-18 43 Numonyx™ Wireless Flash Memory (W18) 7.3 Reset Specifications Note: Specifications are for 130 nm and 90 nm devices unless otherwise stated. Program W400 tEFP/W Single Word 4 N/A N/A 3.1 16 µs W401 tEFP/PB 4-Kword Parameter Block 2,3 N/A - 15 - ms W402 tEFP/MB 32-Kword Main Block 2,3 N/A - 120 - ms Operation Latency W403 tEFP/SETUP EFP Setup - N/A - 5 µs W404 tEFP/TRAN Program to Verify Transition N/A N/A 2.7 5.6 µs W405 tEFP/VERIFY Verify N/A N/A 1.7 130 µs Notes: 1. Unless noted otherwise, all parameters are measured at TA = +25 °C and nominal voltages, and they are sampled, not 100% tested. 2. Excludes external system-level overhead. 3. Exact results may vary based on system overhead. 4. W400-Typ is the calculated delay for a single programming pulse. W400-Max includes the delay when programming within a new word-line. 5. Some EFP performance degradation may occur if block cycling exceeds 10. Table 17: Erase and Program Times (Sheet 2 of 2) Operation Symbol Parameter Description (1) Notes VPP1 VPP2 Unit Typ Max Typ Max Table 18: Reset Specifications # Symbol Parameter (1) Notes Min Max Unit P1 tPLPH RST# Low to Reset during Read 1, 2, 3, 4 100 - ns P2 tPLRH RST# Low to Reset during Block Erase 1, 3, 4, 5 - 20 µs RST# Low to Reset during Program 1, 3, 4, 5 - 10 µs P3 tVCCPH VCC Power Valid to Reset 1,3,4,5,6 60 - µs Notes: 1. These specifications are valid for all product versions (packages and speeds). 2. The device may reset if tPLPH< tPLPHMin, but this is not guaranteed. 3. Not applicable if RST# is tied to VCC. 4. Sampled, but not 100% tested. 5. If RST# is tied to VCC, the device is not ready until tVCCPH occurs after when VCC ≥ VCCMin. 6. If RST# is tied to any supply/signal with VCCQ voltage levels, the RST# input voltage must not exceed VCC until VCC ≥ VCCMin. |
