DESCRIPTION:
The IDT70V05 is a high-speed 8K x 8 Dual-Port Static RAM. The IDT70V05 is designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port 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.

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
   — IDT70V05S
      Active: 350mW (typ.)
      Standby: 3.5mW (typ.)
   — IDT70V05L
      Active: 350mW (typ.)
      Standby: 1mW (typ.)
• IDT70V05 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
• Battery backup operation—2V data retention
• LVTTL-compatible, single 3.3V (±0.3V) power supply
• Available in 68-pin PGA, 68-pin PLCC, and a 64-pin TQFP
