NOTES:

2. Temperature Conversion is inactive below 2.7V VBAT

3. IRQ/FOUT Inactive.

4. VIL = VDD x 0.1, VIH = VDD x 0.9, fSCL = 400kHz

5. VDD > VBAT +VBATHYS

6. Bit BSW = 0 (Standard Mode), VBAT ≥ 1.8V

7. Specified at +25°C.

8. In order to ensure proper timekeeping, the VDD SR- specification must be followed.

9. Parameter is not 100% tested.

10. These are I2C specific parameters and are not tested, however, they are used to set conditions for testing devices to validate specification.

I2C Interface Specifications

Test Conditions: VDD=+2.7 to +5.5V, Temperature = -20°C to +70°C, unless otherwise specified. (Continued)
