Description
HIGH-SPEED 64K x 8 DUAL-PORT STATIC RAM
IDT70V08S/L
Features
x True Dual-Ported memory cells which allow simultaneous access of the same memory location
x High-speed access – Commercial: 15/20/25/35ns (max.)
x Low-power operation – IDT70V08S Active: 550mW (typ.) Standby: 5mW (typ.) – IDT70V08L Active: 550mW (typ.) Standby: 1mW (typ.)
x Dual chip enables allow for depth expansion without external logic
x IDT70V08 easily expands data bus width to 16 bits or
more using the Master/Slave select when cascading more
than one device x M/S = VIH for BUSY output flag on Master,
M/S = VIL for BUSY input on Slave x Busy and Interrupt Flags x On-chip port arbitration logic x Full on-chip hardware support of semaphore signaling
between ports x Fully asynchronous operation from either port x LVTTL-compatible, single 3.3V (±0.3V) power supply x Available in a 100-pin TQFP x Industrial temperature range (–40°C to +85°C) is available
for selected speeds
