HIGH-SPEED 2.5V  
256/128/64K x 36  
IDT70T3519/99/89S  
SYNCHRONOUS  
DUAL-PORT STATIC RAM  
WITH 3.3V OR 2.5V INTERFACE  
Features:  
– 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  
2.5V (±100mV) 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 256-pin Ball Grid Array (BGA), a 208-pin  
Plastic Quad Flatpack (PQFP) and 208-pin fine pitch Ball  
Grid Array (fpBGA)  
Supports JTAG features compliant with IEEE 1149.1  
Due to limited pin count JTAG is not supported on the 208-  
pin PQFP package  
◆
True Dual-Port memory cells which allow simultaneous  
access of the same memory location  
High-speed data access  
◆

NOTES:  
1. Address A17 is a NC for the IDT70T3599. Also, Addresses A17 and A16 are NC's for the IDT70T3589.  
2. The sleep mode pin shuts off all dynamic inputs, except JTAG inputs, when asserted. All static inputs, i.e., PL/FTx and OPTx  
APRIL 2004  
and the sleep mode pins themselves (ZZx) are not affected during sleep mode.
