IDT70V05S/L  
HIGH-SPEED 3.3V  
8K x 8 DUAL-PORT  
STATIC RAM  
Integrated Device Technology, Inc.  
• On-chip port arbitration logic  
• Full on-chip hardware support of semaphore signaling  
between ports  
• Fully asynchronous operation from either port  
• Devices are capable of withstanding greater than 2001V  
electrostatic discharge  
FEATURES:  
• True Dual-Ported memory cells which allow simulta-  
neous access of the same memory location  
• High-speed access  
— Commercial: 25/35/55ns (max.)  
• Low-power operation  
• Battery backup operation—2V data retention  
— IDT70V05S  
LVTTL-compatible, single 3.3V (±0.3V) power supply  
Active: 350mW (typ.)  
Standby: 3.5mW (typ.)  
— IDT70V05L  
• Available in 68-pin PGA, 68-pin PLCC, and a 64-pin  
TQFP  
Active: 350mW (typ.)  
Standby: 1mW (typ.)  
DESCRIPTION:  
• IDT70V05 easily expands data bus width to 16 bits or  
more using the Master/Slave select when cascading  
more than one device  
• M/S = H for BUSY output flag on Master  
M/S = L for BUSY input on Slave  
• Busy and Interrupt Flags  
The IDT70V05 is a high-speed 8K x 8 Dual-Port Static  
RAM. The IDT70V05 is designed to be used as a stand-alone  
Dual-Port RAM or as a combination MASTER/SLAVE Dual-  
Port RAM for 16-bit-or-more word systems. Using the IDT  
MASTER/SLAVE Dual-Port RAM approach in 16-bit or wider  
memory system applications results in full-speed, error-free
