STATIC RAM WITH INTERRUPTS

ꢀeatures

◆

MASTER IDT71V321 easily expands data bus width to 16-

or-more-bits using SLAVE IDT71V421

High-speed access

– Commercial: 25/35/55ns (max.)

– Industrial: 25ns (max.)

Low-power operation

◆

On-chip port arbitration logic (IDT71V321 only)

BUSY output flag on IDT71V321; BUSY input on IDT71V421

Fully asynchronous operation from either port

Battery backup operation—2V data retention (L only)

TTL-compatible, single 3.3V power supply

Available in 52-pin PLCC, 64-pin TQFP and STQFP

packages

◆

– IDT71V321/IDT71V421S

— Active: 325mW (typ.)

— Standby: 5mW (typ.)

– IDT71V321/V421L

— Active: 325mW (typ.)

— Standby: 1mW (typ.)

◆

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

for selected speeds

◆

Two INT flags for port-to-port communications

NOTES:

1. IDT71V321 (MASTER): BUSY is an output. IDT71V421 (SLAVE): BUSY is input.

2. BUSY and INT are totem-pole outputs.
