HIGH-SPEED 3.3V

64K x 16 DUAL-PORT

STATIC RAM

.eatures

True Dual-Ported memory cells which allow simultaneous

access of the same memory location

High-speed access

– Commercial: 15/20ns (max.)

– Industrial: 20ns (max.)

Low-power operation

– IDT70V28L

Active: 440mW (typ.)

Standby: 660µW (typ.)

Dual chip enables allow for depth expansion without

external logic

IDT70V28 easily expands data bus width to 32 bits or

more using the Master/Slave select when cascading more

than one device

On-chip port arbitration logic

Full on-chip hardware support of semaphore signaling

between ports

Fully asynchronous operation from either port

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

plexed bus and bus matching compatibility

LVTTL-compatible, single 3.3V (±0.3V) power supply

Available in a 100-pin TQFP

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

for selected speeds
