Note 7:
All voltages are referenced to V SS .
Programming of the EPROM Data and EPROM Status fields require a limited temperature range of 0 ° C to 50 ° C and limited V DD
voltage range of 3.0V to 5.5V.
Storage for t EES at +50 ° C.
DQ < V IL for t > 1.5ms or DQ > V IH for t > 1.5ms [1-Wire oscillator shut down].
Programming pulse on DQ pin must be shaped to conform with rise, fall, and width timing specifications. See Figure 7. EPROM
Programming Diagram).
The accumulative duration of all programming pulses for each address must not exceed 5ms.
Specification is guaranteed by design.
