Description
The IDT70121/IDT70125 are high-speed 2K x 9 Dual-Port Static RAMs. The IDT70121 is designed to be used as a stand-alone 9-bit Dual- Port RAM or as a “MASTER” Dual-Port RAM together with the IDT70125 “SLAVE” Dual-Port in 18-bit-or-more word width systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 18-bit-or-wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.

Features
✵ High-speed access
   – Commercial: 25/35/45/55ns (max.)
   – Industrial: 35ns (max.)
◆ Low-power operation
   – IDT70121/70125S
      Active: 675mW (typ.)
      Standby: 5mW (typ.)
   – IDT70121/70125L
      Active: 675mW (typ.)
      Standby: 1mW (typ.)
◆ Fully asychronous operation from either port
◆ MASTER IDT70121 easily expands data bus width to 18 bits or
   more using SLAVE IDT70125 chip
◆ On-chip port arbitration logic (IDT70121 only)
◆ BUSY output flag on Master; BUSY input on Slave
◆ INT flag for port-to-port communication
◆ Battery backup operation—2V data retention
◆ TTL-compatible, signal 5V (±10%) power supply
◆ Available in 52-pin PLCC
◆ Industrial temperature range (–40°C to +85°C) is available for
   selected speeds
◆ Green parts available, see ordering information
