IDT7005S/L
HIGH-SPEED
8K x 8 DUAL-PORT
STATIC RAM
FEATURES:
? True Dual-Ported memory cells which allow simulta-
neous access of the same memory location
? High-speed access
— Military: 20/25/35/55/70ns (max.)
— Commercial:15/17/20/25/35/55ns (max.)
? Low-power operation
— IDT7005S
Active: 750mW (typ.)
Standby: 5mW (typ.)
— IDT7005L
Active: 750mW (typ.)
Standby: 1mW (typ.)
? 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.
