EP7309
High-Performance, Low-Power System on Chip
Note:
1) All power dissipation values can be derived from taking the particular IDD current and multiplying by 2.5 V.
2) The RTC of the EP7309 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 –20
°
C extended and 0

commercial.
3) A typical design will provide 3.3 V to the I/O supply (i.e., V
DD
IO), 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.
4) Pull-up current = 50 μA typical at V
DD
= 3.3 V.
