IDT7005 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
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
Battery backup operation—2V data retention
TTL-compatible, single 5V (
±10%) power supply
Available in 68-pin PGA, 68-pin quad flatpack, 68-pin
PLCC, and a 64-pin TQFP
Industrial temperature range (–40
°C to +85°C) is avail-
able, tested to military electrical specifications
DESCRIPTION:
The IDT7005 is a high-speed 8K x 8 Dual-Port Static RAM.
The IDT7005 is designed to be used as a stand-alone Dual-
Port RAM or as a combination MASTER/SLAVE Dual-Port
NOTES:
1. (MASTER):
BUSY is output;
(SLAVE):
BUSY
is input.
2.
BUSY outputs
and
INT outputs
are non-tri-stated
push-pull.
