HIGH-SPEED
16K X 9 DUAL-PORT
STATIC RAM
IDT7016S/L
Features
â True Dual-Ported memory cells which allow simulta-
neous reads of the same memory location
â High-speed access
â Commercial:12/15/20/25/35ns (max.)
â Industrial: 20ns (max.)
â Military: 20/25/35ns (max.)
â Low-power operation
â IDT7016S
Active: 750mW (typ.)
Standby: 5mW (typ.)

Standby: 1mW (typ.)
â IDT7016 easily expands data bus width to 18 bits or
more using the Master/Slave select when cascading
more than one device
â M/S = VIH for BUSY output flag on Master
M/S = VIL for BUSY input on Slave
â Busy and Interrupt Flag
â On-chip port arbitration logic
â Full on-chip hardware support of semaphore signaling
between ports
â Fully asynchronous operation from either port
â TTL-compatible, single 5V (±10%) power supply
â Available in ceramic 68-pin PGA, 68-pin PLCC, and an
80-pin TQFP
â Industrial temperature range (â40°C to +85°C) is
available for selected speeds
â Green parts available, see ordering information

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