Electrical Specififcation
2.1.2 External Signal Levels
External signal levels must not be higher than power supply voltage by 0.5V or more (3.3V inputs). If a
signal with 0.5V or more than VDDE is given to an input buffer the current will flow internally to supply,
which can give a permanent damage to the LSI.
In addition, when power supply becomes on or off, signal levels must not be higher than the power supply
voltage by 0.5V or more. This means that signals must not be applied before power on / after power off.
If an external signal (5V) is input at a 5V tolerant input before the device in question is powered-on, it will
give the LSI a permanent damage.
2.1.3 APLL Power Supply Level
APLL (Analog PLL) power supply level must not be higher than power supply voltage VDDI. Please take
care of APLL power supply not to be over VDDI level at Power ON/OFF sequence.
2.1.4 DAC supply
DAC supply is isolated from other 2.5V supply.
2.1.5 SDRAM Supply
SDRAM supply must be as same level as VDDI (Jasmine only).
