HIGH-SPEED

IDT7026S/L

16K x 16 DUAL-PORT

STATIC RAM

Integrated Device Technology, Inc.

FEATURES:

• True Dual-Ported memory cells which allow simulta-

neous 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

— Military: 25/35/55ns (max.)

— Commercial: 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

— IDT7026S

• Full on-chip hardware support of semaphore signaling

between ports

Active: 750mW (typ.)

Standby: 5mW (typ.)

— IDT7026L

Active: 750mW (typ.)

Standby: 1mW (typ.)

• Separate upper-byte and lower-byte control for

multiplexed bus compatibility

• 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 avail-

able, tested to military electrical specifications
