The IDT 75P52100 NSE device has a bi-directional bus that is a multiplexed address and data bus that can support 100 million sustained searches per second. This device provides array segments which can be configured to enable multiple width lookups from 36 to 576 bits wide. The IDT 75P52100 requires a 1.8-volt VDD supply, a user selectable 1.8 or 2.5-volt VDDQ supply, and a 2.5-volt VBIAS supply. This NSE device 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 CMOS processing technology and is packaged in a JEDEC Standard, thermally enhanced, low profile Ball Grid Array. 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.
