HIGH-SPEED

IDT7025S/L

8K x 16 DUAL-PORT

STATIC RAM

◆

IDT7025 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

Interrupt Flag

On-chip port arbitration logic

Full on-chip hardware support of semaphore signaling

between ports

Fully asynchronous operation from either port

Battery backup operation—2V data retention

TTL-compatible, single 5V (±10%) power supply

Available in 84-pin PGA, Flatpack, PLCC, and 100-pin Thin

Quad Flatpack

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:55ns (max.)

◆

– Commercial:15/17/20/25/35/55ns(max.)

Low-power operation

◆

– IDT7025S

◆

Active:750mW(typ.)

Standby: 5mW (typ.)

– IDT7025L

Active:750mW(typ.)

Standby: 1mW (typ.)

Separate upper-byte and lower-byte control for multiplexed

◆

Industrial temperature range (–40°C to +85°C) is available

for selected speeds
