Description
HIGH-SPEED 3.3V 32K x 8 DUAL-PORT STATIC RAM
Integrated Device Technology, Inc.
IDT70V07S/L
FEATURES:
True Dual-Ported memory cells which allow simultaneous access of the same memory location High-speed access — Commercial: 25/35/55ns (max.) Low-power operation — IDT70V07S Active: 450mW (typ.) Standby: 5mW (typ.) — IDT70V07L Active: 450mW (typ.) Standby: 5mW (typ.) IDT70V07 easily expands data bus width to 16 bits or more using the Master/Slave select when cascading more than one device M/S = H for BUSY output flag on Master M/S = L 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 Devices are capable of withstanding greater than 2001V electrostatic discharge LVTTL-compatible, single 3.3V (± 0.3V) power supply Available in 68-pin PGA, 68-pin PLCC, and a 64-pin TQFP
DESCRIPTION:
The IDT70V07 is a high-speed 32K x 8 Dual-Port Static RAM. The IDT70V07 is designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE DualPort RAM for 16-bit-or-more word systems. 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.
