Note: 1. Valid for Ambient Operating Temperature: T
A
= 0 to 70°C; V
CC
= 4.5 to 5.5V or 3.0 to 3.6V (except where noted).
2. RSTIN1 and RSTIN2 internally pulled-up to V
CC
through 100K
resistor. WDI internally pulled-down to V
SS
through 100K
resistor.
3. Outputs deselected.
4. For IRQ/FT & RST pins (Open Drain).
5. Conditioned outputs (E
CON
- G
CON
) can only sustain CMOS leakage currents in the battery back-up mode. Higher leakage currents
will reduce battery life.
6. External SRAM must match TIMEKEEPER SUPERVISOR chip V
