NOTES:

1. All voltages are referenced to ground.

2. Logic 1 voltages are specified at a source current of 1 mA.

3. Logic 0 voltages are specified at a sink current of 4 mA.

4. I

specified with DQ pin open and CLK pin at V

5. I

specified with V

at 5.0V and RST =GND.

6. Measured at V

= 2.0V or V

= 0.8V.

7. Measured at V

= 2.4V or V

= 0.4V.

8. Load capacitance = 50 pF.

9. t

CWH

must be 10 ms minimum following any write command that involves the E

memory.

10. See typical curve for specification limits outside 0°C to 70°C range.

11. Thermometer error reflects temperature accuracy as tested during calibration.

12. Writing to the nonvolatile memory should only take place in the 0°C to 70°C temperature range.

13. Valid for design revisions D1 and above. The supply range for Rev. C2 and below is 4.5V < 5.5V.
