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

◆

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 (12Gbps 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, 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 208-pin Plastic Quad Flatpack (PQFP),

208-pin fine pitch Ball Grid Array (fpBGA), and 256-pin Ball

Grid Array (BGA)

◆

Supports JTAG features compliant with IEEE 1149.1
