Description
The IDT70V261S/L is a high-speed, 3.3V, 16K x 16 dual-port static RAM with true dual-ported memory cells that allow simultaneous access to the same memory location. It features low-power operation, separate upper-byte and lower-byte control for multiplexed bus compatibility, and an on-chip port arbitration logic.
Features
True dual-ported memory cells
High-speed access:
Commercial: 25/35ns (max.)
Industrial: 25ns (max.)
Low-power operation:
IDT70V261S:
Active: 300mW (typ.)
Standby: 3.3mW (typ.)
IDT70V261L:
Active: 300mW (typ.)
Standby: 660μW (typ.)
Separate upper-byte and lower-byte control for multiplexed bus compatibility
On-chip port arbitration logic
Full on-chip hardware support of semaphore signaling between ports
Fully asynchronous operation from either port
TTL-compatible, single 3.3V (±0.3V) power supply
Available in a 100-pin TQFP
Industrial temperature range (-40°C to 85°C) available for selected speed
Applications
Data buffering
Cache memory
Shared memory
Semaphore signaling
Multiprocessor systems
