Description
HIGH-SPEED 3.3V 128/64K x 36
IDT70V3599/89S
SYNCHRONOUS DUAL-PORT STATIC RAM
WITH 3.3V OR 2.5V INTERFACE
LEAD FINISH (containing SnPb) are obsolete excluding the BGA and Hermetic packages
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-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, 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 ◆ Green parts available, see ordering information
