71V2556SA - 3.3V Synchronous SRAMs

Download the 71V2556SA datasheet PDF. This datasheet also covers the 71V2556S variant, as both devices belong to the same 3.3v synchronous srams family and are provided as variant models within a single manufacturer datasheet.

Description

The IDT71V2556 is a 3.3V high-speed 4,718,592-bit (4.5 Megabit) synchronous SRAM.

It is designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads.

Thus, they have been given the name ZBTTM, or Zero Bus Turnaround.

Features

  • 128K x 36 memory configurations.
  • Supports high performance system speed - 166 MHz (3.5 ns Clock-to-Data Access).
  • ZBTTM Feature - No dead cycles between write and read cycles.
  • Internally synchronized output buffer enable eliminates the need to control OE.
  • Single R/W (READ/WRITE) control pin.
  • Positive clock-edge triggered address, data, and control signal registers for fully pipelined.
