3.3V, 8Mb, Nonvolatile SRAM with Clock

6

Note 1: All voltages are referenced to ground.

Note 2: These parameters are sampled with a 5pF load and are not 100% tested.

Note 3: tWP is specified as the logical AND of CE with WE for SRAM writes, or CS with WE for RTC writes. tWP is measured from

the later of the two related edges going low to the earlier of the two related edges going high.

Note 4: tWR1 and tDH1 are measured from WE going high.

Note 5: tWR2 and tDH2 are measured from CE going high for SRAM writes or CS going high for RTC writes.

Note 6: tDS is measured from the earlier of CE or WE going high for SRAM writes, or from the earlier of CS or WE going high for

RTC writes.

Note 7: In a power-down condition, the voltage on any pin cannot exceed the voltage on VCC.

Note 8: The expected tDR is defined as accumulative time in the absence of VCC starting from the time power is first applied

by the user. Minimum expected data-retention time is based upon a single convection reflow exposure, followed by an

attachment of a new DS9034I-PCX+. This parameter is assured by component selection, process control, and design. It

is not measured directly during production testing.

Note 9: WE is high for any read cycle.

Note 10: VOE = VIH or VIL. If VOE = VIH during write cycle, the output buffers remain in a high-impedance state.

Note 11: If the CE or CS low transition occurs simultaneously with or later than the WE low transition, the output buffers remain in a

high-impedance state during this period.

Note 12: If the CE or CS high transition occurs prior to or simultaneously with the WE high transition, the output buffers remain in a

high-impedance state during this period.

Note 13: If WE is low or the WE low transition occurs prior to or simultaneously with the related CE or CS low transition, the output

buffers remain in a high-impedance state during this period.
