TheIDT75P52100requiresa1.8-voltVDDsupply,auserselectable1.8  
or2.5-voltVDDQ supply,anda2.5-voltVBIAS supply. This NSEdevice  
provides the user with flexibility and control in determining the device  
power. Only the array segments that will be used for a specific NSE  
operation are powered up while the unused segments are not.  
The IDT 75P52100 utilizes IDT’s latest high-performance 1.8V  
CMOSprocessingtechnologyandis packagedinaJEDECStandard,  
thermallyenhanced, lowprofile BallGridArray. The options include a  
304 BGA, satisfying smaller footprint requirements and a 372 BGA  
package that is compatible with IDT's 32K x 72 Entry (75P42100) and  
128K x 72 Entry (75P62100) NSE devices.
