KE5BCCA1M Classification CAM Kawasaki LSI’s Classification CAM has a capacity of 1Mbit (Ternary) and 2 Mbit (Binary), and can be configured by bank in a mixture of binary and ternary modes. Its primary application is in search and filtering. Its flexibility, high speed, and high capacity make it appropriate for all Layer 2/3/4 and above applications such as switches and routers in 10/100/1000 Ethernet, Terabit Ethernet ,OC-3/12/48/192, T1/T3, frame relay, ATM, xDSL and DWDM. This Classification CAM is also suitable for QoS applications with its unique and patent-pending “Auto Shift” commands. The search time is 15ns and the KE5BCCA1M is available in a 324-pin BGA. FEATURES: • • High density: 2Mbits Binary, 1Mbit for Ternary Organization: Configurable table width; binary/ternary selected by bank • Binary case: 68-bit x 32k, 136-bit x 16k, 272-bit x 8k • Ternary case: 68-bit x 16k, 136-bit x 8k, 272-bit x 4k • High Speed Search :15n sec (1 phase clock) • Latency: 30n sec (2 clock cycles) • Dual-Port Architecture: 68-bit I/O port with 1. 64-bit data bus (optional 32-bit configuration) 2. Optional 4 extra bits on the data bus 3. 32-bit output port • Cascadable up to 32 pieces • • • • • • • • • • Support for automatic data shifting Continuous search during data shifting. Multi-hit support (highest hit address output) 18 Global MASK Registers (68-bit width) for data search/writing operation. Automatic learning Automatic storing of miss-hit data and time stamp of hit data Synchronous operation Clock rate: 66MHz (phase clock)/133MHz (operating clock) for synchronous operation 324-pin BGA packaging 2.5V/3.3V power supply DAT<63:0> EDAT<3:0> I/O Port Control Output Port Control OEDATN Control and Status Register DATWDT EXTONN OEODN OD<31:0> Mask Registers Search Logic Control Logic CLK PHASE SAD EAD Kawasaki LSI USA, Inc.
