HMD8M32F4E

I_IL: Input Leakage Current (Any input 0V £ V_IN£ 6.5V, all other pins not under test = 0V)

I_OL: Output Leakage Current (Data out is disabled, 0V £ V_OUT£ 5.5V

V_OH: Output High Voltage Level (I_OH= -5mA )

V_OL: Output Low Voltage Level (I_OL= 4.2mA )

* NOTE: I_CC1, I_CC3, I_CC4and I_CC6are dependent on output loading and cycle rates. Specified values are obtained with

the output open. I_CCis specified as an average current. In I_CC1and I_CC3, address cad be changed maximum

once while /RAS=V_IL. In I_CC4, address can be changed maximum once within one page mode cycle.
