HIGH-SPEED

IDT7026S/L

16K X 16 DUAL-PORT

STATIC RAM

Features

◆

True Dual-Ported memory cells which allow simultaneous

access of the same memory location

High-speed access

IDT7026 easily expands data bus width to 32 bits or more

using the Master/Slave select when cascading more than

one device

◆

– Commercial: 15/20/25/35/55ns (max.)

– Industrial: 20/25/35/55ns (max.)

– Military: 20/25/35/55ns (max.)

Low-power operation

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

– IDT7026S

◆

Active: 750mW (typ.)

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

Standby: 5mW (typ.)

– IDT7026L

Active: 750mW (typ.)

Standby: 1mW (typ.)

◆

Separate upper-byte and lower-byte control for multi-

plexed bus compatibility

Green parts available, see ordering information

NOTES:

1. (MASTER): BUSY is output; (SLAVE): BUSY is input.

2. BUSY outputs are non-tri-stated push-pull.
