Features
◆
True Dual-Ported memory cells which allow simultaneous
access of the same memory location
◆
High-speed access
– Commercial: 15/20/25/35/55ns (max.)
– Industrial: 20/25/35/55ns (max.)
– Military: 20/25/35/55ns (max.)
◆
Low-power operation
– IDT7026S
Active: 750mW (typ.)
Standby: 5mW (typ.)
– IDT7026L
Active: 750mW (typ.)
Standby: 1mW (typ.)
◆
Separate upper-byte and lower-byte control for multi-
plexed bus compatibility
◆
IDT7026 easily expands data bus width to 32 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
◆
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 84-pin PGA and 84-pin PLCC
◆
Industrial temperature range (-40°C to +85°C) is available
for selected speeds

NOTES:
1. (MASTER): BUSY is output; (SLAVE): BUSY is input.
2. BUSY outputs are non-tri-stated push-pull.
