IDT70125L Datasheet High-speed 2k X 9 Dual-port Static Ram

Manufacturer: Integrated Device Technology

Overview: HIGH-SPEED 2K x 9 DUAL-PORT STATIC RAM WITH BUSY & INTERRUPT Integrated Device Technology, Inc.

General 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 18bit-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.

Key Features

  • High-speed access.
  • Commercial: 25/35/45/55ns (max. ).
  • Low-power operation.
  • IDT70121/70125S Active: 500mW (typ. ) Standby: 5mW (typ. ).
  • IDT70121/70125L Active: 500mW (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.
