◆
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 ceramic 68-pin PGA, 68-pin PLCC, and an 80-
pin TQFP
◆
Industrial temperature range (–40°C to +85°C) is available
for selected speeds
Features:
◆
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.)
– Mlitary: 20/25/35ns (max.)
◆
Low-power operation
– IDT7015S
Active: 750mW (typ.)
Standby: 5mW (typ.)
– IDT7015L
Active: 750mW (typ.)
Standby: 1mW (typ.)
◆
IDT7015 easily expands data bus width to 18 bits or more
using the Master/Slave select when cascading more than
one device
HIGH-SPEED
8K x 9 DUAL-PORT
STATIC RAM
IDT7015S/L
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.
