IS61QDPB42M36B1 - 72Mb QUADP SYNCHRONOUS SRAM

Download the IS61QDPB42M36B1 datasheet PDF. This datasheet also covers the IS61QDPB44M18B variant, as both devices belong to the same 72mb quadp synchronous sram family and are provided as variant models within a single manufacturer datasheet.

General Description

The 72Mb IS61QDPB42M36B/B1/B2 and IS61QDPB44M18B/B1/B2 are synchronous, highperformance CMOS static random access memory (SRAM) devices.

These SRAMs have separate I/Os, eliminating the need for high-speed bus turnaround.

Key Features

  • 2Mx36 and 4Mx18 configuration available.
  • On-chip Delay Locked Loop (DLL) for wide data valid window.
  • Separate independent read and write ports with concurrent read and write operations.
  • Synchronous pipeline read with late write operation.
  • Double Data Rate (DDR) interface for read and write input ports.
  • 2.5 cycle read latency.
  • Fixed 4-bit burst for read and write operations.
  • Clock stop support.
  • Two input clocks (K and K#) for address and contr.
