NOTE:
All power dissipation values can be derived from taking the particular IDD current and multiplying by
2.5 V.
The RTC of the EP7211 should be brought up at room temperature. This is required because the RTC
OSC will NOT function properly if it is brought up at
–
40
°
C. Once operational, it will continue to oper-
ate down to
–
40
°
C
.
A typical design will provide 3.3 V to the I/O supply (i.e., VDDIO), and 2.5 V to the remaining logic.
This is to allow the I/O to be compatible with 3.3 V powered external logic (e.g., 3.3 V DRAMs).
Pull-up current = 50 μA typical at V
