IDT71V546S - Synchronous SRAM

Description

The IDT71V546 is a 3.3V high-speed 4,718,592-bit (4.5 Megabit) synchronous SRAM organized as 128K x 36 bits.

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

Thus it has been given the name ZBTTM, or Zero Bus Turn-around.

Features

  • 128K x 36 memory configuration, pipelined outputs.
  • Supports high performance system speed - 133 MHz (4.2 ns Clock-to-Data Access).
  • ZBTTM Feature - No dead cycles between write and read cycles.
  • Internally synchronized registered outputs eliminate the need to control OE.
  • Single R/W (READ/WRITE) control pin Functional Block Diagram LBO Address A [0:16] CE1, CE2, CE2 R/W CEN ADV/LD BWx DQ DQ.
  • Positive clock-edge triggered address, data, and control signal registers.
