PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS Programming Pulse Width tPP (Notes 1, 2, 5, 6) 480 5000 ms Program Voltage Rise Time tRP (Notes 1, 2, 5) 0.5 5.0 ms Program Voltage Fall Time tFP (Notes 1, 2, 5) 0.5 5.0 ms Programming Current: DQ Pin IPP (Notes 2, 5, 7) 6 10 mA AC ELECTRICAL CHARACTERISTICS: 1-Wire INTERFACE (2.2V £ VDD £ 5.5V, TA = -30°C to +85°C.) PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS Time Slot tSLOT 60 120 ms Recovery Time tREC 1 ms Write-0 Low Time tLOW0 60 120 ms Write-1 Low Time tLOW1 1 15 ms Read-Data Valid tRDV 15 ms Reset-Time High tRSTH 480 ms Reset-Time Low tRSTL 480 960 ms Presence-Detect High tPDH 15 60 ms Presence-Detect Low tPDL 60 240 ms Delay to Program Pulse tDP 5 ms Delay to Verify tDV 5 ms DQ Capacitance CDQ 50 pF Note 1: All voltages are referenced to VSS. Note 2: Programming of the EPROM Data and EPROM Status fields require a limited temperature range of 0 °C to 50°C and limited VDD voltage range of 3.0V to 5.5V. Note 3: Storage for tEES at +50 °C. Note 4: DQ < VIL for t > 1.5ms or DQ > VIH for t > 1.5ms [1-Wire oscillator shut down]. Note 5: Programming pulse on DQ pin must be shaped to conform with rise, fall, and width timing specifications. See Figure 7. EPROM Programming Diagram). Note 6: The accumulative duration of all programming pulses for each address must not exceed 5ms. Note 7: Specification is guaranteed by design. |
