Overview
HIGH-SPEED 3.
3V 64K x 8 DUAL-PORT STATIC RAM 70V08L Features ◆ True Dual-Ported memory cells which allow simultaneous access of the same memory location ◆ High-speed access – Commercial: 15ns (max.
) – Industrial: 20ns (max.
) ◆ Low-power operation – IDT70V08L Active: 550mW (typ.
) Standby: 1mW (typ.
) ◆ Dual chip enables allow for depth expansion without external logic ◆ IDT70V08 easily expands data bus width to 16 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 ◆ Busy and Interrupt Flags ◆ On-chip port arbitration logic ◆ Full on-chip hardware support of semaphore signaling between ports ◆ Fully asynchronous operation from either port ◆ LVTTL-compatible, single 3.

V 64K x 8 Dual-Port Static RAM Description The IDT70V08 is a high-speed 64K x 8 Dual-Port Static RAM.
The IDT70V08 is designed to be used as a stand-alone 512K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 16-bitor-more word system.
Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic...
