The IDT 75K62100 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 75K62100 requires a 1.2-volt VDD supply and a 2.5-volt VDDQ 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.
