IDT70V05S/L  
HIGH-SPEED 3.3V  
8K x 8 DUAL-PORT  
STATIC RAM  
Features  
True Dual-Ported memory cells which allow simultaneous  
reads of the same memory location  
High-speed access  
one device  
M/S = VIH for BUSY output flag on Master  
M/S = VIL for BUSY input on Slave  
Interrupt Flag  
On-chip port arbitration logic  
Commercial: 15/20/25/35/55ns (max.)  
Industrial: 20ns (max.)  
Low-power operation  
Full on-chip hardware support of semaphore signaling  
between ports  
IDT70V05S  
Active:400mW(typ.)  
Standby: 3.3mW (typ.)  
IDT70V05L  
Fully asynchronous operation from either port  
TTL-compatible, single 3.3V (±0.3V) power supply  
Available in 68-pin PGA and PLCC, and a 64-pin TQFP  
Industrial temperature range (-40°C to +85°C) is available  
for selected speeds  
Active:380mW(typ.)  
Standby: 660µW (typ.)  
IDT70V05 easily expands data bus width to 16 bits or more  
using the Master/Slave select when cascading more than  
Green parts available, see ordering information
