Overview of IS42S16160L-7TL - 256Mbit Synchronous DRAM

The IS42S16160L-7TL is a 256-megabit synchronous dynamic random access memory (SDRAM) organized as 16M x 16 and manufactured by ISSI, Integrated Silicon Solution Inc. This volatile memory device operates with a 143 MHz clock frequency and provides fast 5.4ns access time for applications requiring reliable parallel memory with moderate speed and density. Designed for commercial temperature range operation (0°C to 70°C), it serves consumer electronics, networking equipment, and embedded systems where standard-grade SDRAM meets performance and cost requirements.

Key Features

  • Memory Organization - 16M x 16 configuration provides 256 megabits of volatile storage in a single package, simplifying board layout for systems requiring this capacity level.
  • Clock Performance - 143 MHz maximum clock frequency with 5.4ns access time delivers sufficient bandwidth for data buffering and moderate-speed processing applications.
  • Power Supply - 3V to 3.6V operation aligns with standard 3.3V logic levels, ensuring compatibility with common microcontrollers and processors.
  • Interface - LVTTL-compatible parallel interface enables direct connection to standard logic families without level shifters.
  • Package - 54-pin TSOP II package (10.16mm width) offers proven reliability and established manufacturability for volume production.
  • Temperature Range - 0°C to 70°C operating range suits commercial indoor environments and consumer products.

Typical Applications

  • Consumer Electronics - This SDRAM provides main memory or frame buffer storage in set-top boxes, digital TVs, and multimedia devices where the 256Mbit capacity and commercial temperature rating meet application requirements at competitive cost.
  • Networking Equipment - Serves as packet buffer memory in routers, switches, and network-attached storage devices operating in climate-controlled environments, where the 143 MHz clock frequency supports moderate throughput demands.
  • Embedded Systems - Functions as working memory for industrial controllers, point-of-sale terminals, and instrumentation operating within the 0°C to 70°C range, providing volatile storage for program execution and data processing.
  • Printer and Imaging Systems - Acts as image buffer memory in office printers, scanners, and copiers, where the 16M x 16 organization efficiently handles raster data and page buffering tasks.

Unique Advantages

  • Established SDRAM Technology: Proven synchronous DRAM architecture reduces design risk and ensures compatibility with existing memory controllers and reference designs.
  • Single-Chip 256Mbit Capacity: Consolidates memory capacity in one component, reducing BOM count and board space compared to multiple lower-density devices.
  • LVTTL Interface Simplicity: Direct connection to standard 3.3V logic eliminates voltage translation circuits, lowering component count and design complexity.
  • Industry-Standard Package: 54-TSOP II footprint matches established PCB layouts and enables multiple-source strategies for supply chain flexibility.
  • Commercial Temperature Grade: 0°C to 70°C specification meets requirements for indoor consumer and commercial applications without premium extended-range pricing.
  • Active Lifecycle Status: Current production availability supports new designs and ensures ongoing supply for product lifecycles.
