HIGH-SPEED 3.3V
256/128K x 18
IDT70V3319/99S
SYNCHRONOUS
DUAL-PORT STATIC RAM
WITH 3.3V OR 2.5V INTERFACE
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.
