1 / 23 page  ©2003 Integrated Device Technology, Inc. MAY 2003 DSC 5623/7 1 Functional Block Diagram Features: ◆ True Dual-Port memory cells which allow simultaneous access of the same memory location ◆ High-speed data access – Commercial: 3.6ns (166MHz)/4.2ns (133MHz) (max.) – Industrial: 4.2ns (133MHz) (max.) ◆ Selectable Pipelined or Flow-Through output mode – Due to limited pin count PL/FT option is not supported on the 128-pin TQFP package. Device is pipelined outputs only on each port. ◆ Counter enable and repeat features ◆ Dual chip enables allow for depth expansion without additional logic ◆ Full synchronous operation on both ports – 6ns cycle time, 166MHz operation (6Gbps bandwidth) – Fast 3.6ns clock to data out – 1.7ns setup to clock and 0.5ns hold on all control, data, and address inputs @ 166MHz – Data input, address, byte enable and control registers – Self-timedwriteallowsfastcycletime ◆ Separate byte controls for multiplexed bus and bus matching compatibility ◆ Dual Cycle Deselect (DCD) for Pipelined Output mode ◆ LVTTL- compatible, single 3.3V (±150mV) power supply for core ◆ LVTTL compatible, selectable 3.3V (±150mV) or 2.5V (±100mV) power supply for I/Os and control signals on each port ◆ Industrial temperature range (-40°C to +85°C) is available at 133MHz. ◆ Available in a 128-pin Thin Quad Flatpack, 208-pin fine pitch Ball Grid Array, and 256-pin Ball GridArray ◆ Supports JTAG features compliant to IEEE 1149.1 – Due to limited pin count, JTAG is not supported on the 128-pin TQFP package.
