71421LA - HIGH SPEED 2K x 8 DUAL-PORT STATIC RAM

Download the 71421LA datasheet PDF. This datasheet also covers the 71421SA variant, as both devices belong to the same high speed 2k x 8 dual-port static ram family and are provided as variant models within a single manufacturer datasheet.

Description

The IDT71321/IDT71421 are high-speed 2K x 8 Dual-Port Static RAMs with internal interrupt logic for interprocessor communications.

Features

  • High-speed access.
  • Commercial: 20/35/55ns (max. ).
  • Industrial: 25/55ns (max. ).
  • Low-power operation.
  • IDT71321/IDT71421SA.
  • Active: 325mW (typ. ).
  • Standby: 5mW (typ. ).
  • IDT71321/421LA.
  • Active: 325mW (typ. ).
  • Standby: 1mW (typ. ).
  • Two INT flags for port-to-port communications.
  • MASTER IDT71321 easily expands data bus width to 16-ormore-bits using SLAVE IDT71421.
  • On-chip port arbitration logic (IDT71321 only).
