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.
