Table 11. DC Characteristics
Note: 1. Valid for Ambient Operating Temperature: T
A
= –40 to 85°C; V
CC
= 2.7 to 3.6V (except where noted).
2. Measured with V
OUT
and E
CON
open.
3. RSTIN1 and RSTIN2 internally pulled-up to V
CC
through 100K
resistor. WDI internally pulled-down to V
SS
through 100K
resistor.
4. Outputs Deselected.
5. External SRAM must match RTC SUPERVISOR chip V
CC
specification.
6. For PFO and SQW pins (CMOS).
7. Conditioned output (E
CON
) can only sustain CMOS leakage current in the battery back-up mode. Higher leakage currents will re-
duce battery life.
8. For IRQ/FT/OUT, RST pins (Open Drain): if pulled-up to supply other than V
CC
, this supply must be equal to, or less than 3.0V when
V
CC
= 0V (during battery back-up mode).
9. For rechargeable back-up, V
BAT
(max) may be considered V
CC
.
