Notes
1.
SCL toggling between VDD-0.3V and VSS, other inputs VSS or VDD-0.3V.
2.
All inputs at VSS or VDD, static. Stop command issued.
3.
VIN or VOUT = VSS to VDD. Does not apply to PFI or /RST pins.
4.
VBAK = 3.0V, VDD < 2.4V, oscillator running, CNT1-2 at VBAK.
5.
/RST is asserted active when VDD < VTP.
6.
The minimum VDD to guarantee the level of /RST remains a valid VOL level.
7.
Full complete operation. Supervisory circuits, RTC, etc operate to lower voltages as specified.
8.
Includes /RST input detection of external reset condition to trigger driving of /RST signal by FM4005.
9.
The VBAK trickle charger automatically regulates the maximum voltage on this pin for capacitor backup applications.
10. VBAK will source current when trickle charger is enabled (VBC bit=1), VDD > VBAK, and VBAK < VBAK max.
AC Parameters (TA = -40° C to + 85° C, VDD = 2.7V to 5.5V, CL = 100 pF unless otherwise specified)
