NOTE:
All power dissipation values can be derived from taking the particular IDD current and multiplying by
2.5 V.
The RTC of the EP7209 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 operate
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 (i.e., 3.3 V DRAMs).
Pull-up current = 50 μA typical at V
DD
= 3.3 volts.
