IDT70T651/9S  
HIGH-SPEED 2.5V  
256/128K x 36  
ASYNCHRONOUS DUAL-PORT  
STATIC RAM  
WITH 3.3V 0R 2.5V INTERFACE  
On-chip port arbitration logic  
Features  
Full on-chip hardware support of semaphore signaling  
between ports  
Fully asynchronous operation from either port  
Separate byte controls for multiplexed bus and bus  
matching compatibility  
True Dual-Port memory cells which allow simultaneous  
access of the same memory location  
High-speed access  
– Commercial:8/10/12/15ns(max.)  
Industrial:10/12ns (max.)  
Sleep Mode Inputs on both ports  
RapidWrite Mode simplifies high-speed consecutive write  
Supports JTAG features compliant to IEEE 1149.1  
Single 2.5V (±100mV) power supply for core  
LVTTL-compatible, selectable 3.3V (±150mV)/2.5V (±100mV)  
power supply for I/Os and control signals on each port  
Available in a 256-ball Ball Grid Array, 208-pin Plastic Quad  
Flatpack and 208-ball fine pitch Ball Grid Array.  
Industrial temperature range (–40°C to +85°C) is available  
for selected speeds  
cycles  
Dual chip enables allow for depth expansion without  
external logic  
IDT70T651/9 easily expands data bus width to 72 bits or  
more using the Master/Slave select when cascading more  
than one device  
M/S = VIH for BUSY output flag on Master,  
M/S = VIL for BUSY input on Slave  
Busy and Interrupt Flags  
Green parts available, see ordering information

NOTES:  
1. Address A17x is a NC for IDT70T659.  
2. BUSY is an input as a Slave (M/S=VIL) and an output when it is a Master (M/S=VIH).  
3. BUSY and INT are non-tri-state totem-pole outputs (push-pull).  
4869 drw 01  
4. The sleep mode pin shuts off all dynamic inputs, except JTAG inputs, when asserted. OPTx, INTx, M/S and the sleep  
mode pins themselves (ZZx) are not affected during sleep mode.
