R8A20210BG Datasheet | Renesas

Description Renesas delivers MARIE_Blade that is a ternary CAM search engine targeted for network packet classifying. The fullcustom CAM memory realizes large capacity, high density and low power consumption. .. MARIE_Blade can realize up to 133 Msps in 72-bit/144-bit normal mode (parallel search 266 Msps), 66.5 Msps in 288bit mode (parallel search 133 Msps) and 33 Msps in 576-bit mode (parallel search 66.5 Msps). The Hierarchical search reduces power consumption; The DX test logic, an extended bit, performs a DX test logic search first (primary search), and the DQ pin performs a DQ array search (secondary search). The parity bit in the DQ array can check for errors as an additional function.
