(T
A
= 25 °C, f = 1 MHz)
Symbol
Note: 1. Sampled only, not 100% tested.
2. Outputs deselected.

Symbol
Note: 1. Outputs deselected.
2. RSTIN1 and RSTIN2 internally pulled-up to V
CC
through 100K
resistor. WDI internally pulled-down to V
SS
through 100K
resistor.
3. For IRQ/FT & RST pins (Open Drain).
4. Conditioned outputs (E1
CON
- E2
CON
) can only sustain CMOS leakage currents in the battery back-up mode. Higher leakage cur-
rents will reduce battery life.
5. External SRAM must match TIMEKEEPER Controller chip V
CC
specification.
6. When fully charged.
