IDT7005S/L
HIGH-SPEED
8K x 8 DUAL-PORT
STATIC RAM
Features
◆ True Dual-Ported memory cells which allow simultaneous
reads of the same memory location
◆ High-speed access
– Military: 20/25/35/55/70ns (max.)
– Industrial: 35/55ns (max.)
– Commercial:15/17/20/25/35/55ns (max.)
◆ Low-power operation
– IDT7005S
Active: 750mW (typ.)
Standby: 5mW (typ.)
– IDT7005L
Active: 700mW (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
◆ Interrupt Flag
◆ 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, quad flatpack, PLCC, and a 64-pin
thin quad flatpack
◆ Industrial temperature range (-40°C to +85°C) is available
for selected speeds
Functional Block Diagram
NOTES:
1. (MASTER):
BUSY is output; (SLAVE): BUSY is input.
2.
BUSY outputs and INT outputs are non-tri-stated push-pull.
