PRELIMINARY  
IDT70V631S  
HIGH-SPEED 3.3V 256K x 18  
ASYNCHRONOUS DUAL-PORT  
STATIC RAM  
Features  
True Dual-Port memory cells which allow simultaneous  
access of the same memory location  
High-speed access  
Fully asynchronous operation from either port  
Separate byte controls for multiplexed bus and bus  
matching compatibility  
Supports JTAG features compliant to IEEE 1149.1  
Due to limited pin count, JTAG is not supported on the  
128-pin TQFP package.  
– Commercial:10/12/15ns (max.)  
Industrial:12/15ns (max.)  
Dual chip enables allow for depth expansion without  
external logic  
IDT70V631 easily expands data bus width to 36 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  
LVTTL-compatible, single 3.3V (±150mV) 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 128-pin Thin Quad Flatpack, 208-ball fine  
pitch Ball Grid Array, and 256-ball Ball Grid Array  
Industrial temperature range (–40°C to +85°C) is available  
for selected speeds  
On-chip port arbitration logic  
Full on-chip hardware support of semaphore signaling  
between ports

NOTES:  
1. BUSY is an input as a Slave (M/S=VIL) and an output when it is a Master (M/S=VIH).  
2. BUSY and INT are non-tri-state totem-pole outputs (push-pull).
