IDT7015S/L  
HIGH-SPEED  
8K x 9 DUAL-PORT  
STATIC RAM  
Features:  
M/S = VIH for BUSY output flag on Master  
M/S = VIL for BUSY input on Slave  
Busy and Interrupt Flag  
On-chip port arbitration logic  
Full on-chip hardware support of semaphore signaling  
between ports  
Fully asynchronous operation from either port  
TTL-compatible, single 5V (±10%) power supply  
Available in 68-pin PLCC and an 80-pin TQFP  
Industrial temperature range (–40°C to +85°C) is available  
for selected speeds  
True Dual-Ported memory cells which allow simultaneous  
reads of the same memory location  
High-speed access  
– Commercial:12/15/17/20/25/35ns(max.)  
– Industrial:20ns(max.)  
Low-poweroperation  
– IDT7015S  
Active:750mW(typ.)  
Standby: 5mW (typ.)  
– IDT7015L

NOTES:  
1. In MASTER mode: BUSY is an output and is a push-pull driver  
In SLAVE mode: BUSY is input.  
2. BUSY outputs and INT outputs are non-tri-stated push-pull drivers.
