R8A20110BG (MARIE) Network Signature Matching Co-Processor (1 M-bit Full Ternary CAM) REJ03H0002-0100 Rev.1.00 Feb 21, 2005 Description “MARIE” is a new RENESAS Ternary CAM co-processor targeted for the network packet classification and signature matching application. MARIE’s 1 M-bit special features, small package and reduced pin count interface makes it www.DataSheet4U.com suitable for cost sensitive platforms. MARIE provides a 36-bit Data bus SSTL-2 interface and is able to achieve 100 Msps in Turbo Mode. During normal search mode MARIE performs 50 Msps at 144-bit lookup. A special shifted payload algorithm for the signature matching makes MARIE a perfect fit for IDS applications. Features 1 M-bit full ternary CAM 100 Msps max. 144-bit LU/288-bit LU with Turbo Search 50 Msps max. 144-bit LU with Normal Search 25 Msps max. 288-bit LU with Normal Search Shifting payload for signature matching application. 36-bit DQ interface (reduced pin count interface) Priority encoder IEEE 1149.1 test port 2.5 V/1.5 V power supply SSTL-2 interface 1.7 × 1.7 mm, 1 mm pitch 256 PBGA Rev.1.00 Feb 21, 2005 page 1 of 8 R8A20110BG (MARIE) Block Diagram TDR DQ[35:0] Header-0 Header-1 TDSR JTAG TDI TDO TMS TCK TRST OID_I Header select Combined Search Data Shifted payload Offset Header Payload www.DataSheet4U.com Search Mask Register OP_ENA OP[5:0] DQS SR_F CLK, ZCLK Control Register Full Ternary CAM Array Priority Encoder RSTL TUE IND OID_O (TRF) Re...
