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-timed write allows fast cycle time
◆
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
Grid Array
◆
Supports JTAG features compliant to IEEE 1149.1
– Due to limited pin count, JTAG is not supported on the
128-pin TQFP package
◆
Green parts available, see ordering information
