HIGH-SPEED 3.3V 128K x 18  
SYNCHRONOUS  
BANK-SWITCHABLE  
IDT70V7399S  
DUAL-PORT STATIC RAM  
WITH 3.3V OR 2.5V INTERFACE  
Features:  
128K x 18 Synchronous Bank-Switchable Dual-ported  
SRAM Architecture  
Data input, address, byte enable and control registers  
– Self-timedwriteallowsfastcycletime  
Separate byte controls for multiplexed bus and bus  
matching compatibility  
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 166MHz and 133MHz  
Available in a 144-pin Thin Quad Flatpack (TQFP),  
208-pin fine pitch Ball Grid Array (fpBGA), and 256-pin Ball  
GridArray(BGA)  
Supports JTAG features compliant with IEEE 1149.1  
Due to limited pin count, JTAG is not supported on the  
144-pin TQFP package.  
64 independent 2K x 18 banks  
– 2 megabits of memory on chip  
Bank access controlled via bank address pins  
High-speed data access  
– Commercial:3.4ns (200MHz)/3.6ns (166MHz)/  
4.2ns (133MHz) (max.)  
Industrial: 3.6 (166MHz)/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  
– 5ns cycle time, 200MHzoperation(14Gbps bandwidth)  
– Fast 3.4ns clock to data out  
– 1.5ns setup to clock and 0.5ns hold on all control, data, and  
address inputs @ 200MHz

1. The Bank-Switchable dual-port uses a true SRAM  
core instead of the traditional dual-port SRAM core.  
As a result, it has unique operating characteristics.  
Please refer to the functional description on page 19  
for details.
