16K x 16 DUAL-PORT
STATIC RAM
IDT70V261S/L
Features
◆ True Dual-Ported memory cells which allow simultaneous
access of the same memory location
◆ High-speed access
– Commercial: 25/35/55ns (max.)
– Industrial: 25ns (max.)
◆ Low-power operation
– IDT70V261S
Active: 300mW (typ.)

– IDT70V261L
Active: 300mW (typ.)
Standby: 660µW (typ.)
◆ Separate upper-byte and lower-byte control for multiplexed
bus compatibility
◆ IDT70V261 easily expands data bus width to 32 bits or more
using the Master/Slave select when cascading more than
one device
◆ M/S = VIH for BUSY output flag on Master
M/S = VIL 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
◆ TTL-compatible, single 3.3V (±0.3V) power supply
◆ Available in a 100-pin TQFP, Thin Quad Plastic Flatpack
◆ Industrial temperature range (-40°C to +85°C) is available
for selected speed
◆ Green parts available, see ordering information
