IS42S16320F-7BL

The IS42S16320F-7BL is a 512Mbit synchronous dynamic random access memory (SDRAM) device from ISSI, Integrated Silicon Solution Inc. Organized as 32M x 16, this parallel-interface DRAM provides reliable, high-density memory storage for embedded systems and computing applications. With a 143MHz clock frequency and 5.4ns access time, it delivers responsive performance for data-intensive operations while operating from a standard 3V to 3.6V supply.

Key Features

• Memory Architecture - 512Mbit capacity organized as 32M words by 16 bits, providing flexible addressing for diverse application requirements.
• Performance Specifications - 143MHz clock frequency with 5.4ns access time enables fast data throughput for real-time processing and buffering tasks.
• Power Supply - Operates on a 3V to 3.6V supply, compatible with standard logic levels in most embedded systems.
• Operating Temperature Range - 0°C to 70°C (TA) temperature rating suits commercial and many industrial applications.
• Package - Available in a compact 54-TFBGA (54-TW-BGA, 8x13mm) package, optimizing board space in size-constrained designs.

Typical Applications

• Embedded Computing Systems - This SDRAM provides main memory or buffer memory for microcontrollers and processors in commercial embedded applications, where the parallel interface and moderate speed support real-time data handling without requiring high-end DDR technologies.
• Consumer Electronics - Ideal for set-top boxes, digital displays, and multimedia devices that require cost-effective volatile memory with sufficient bandwidth for video buffering and user interface operations within the 0°C to 70°C operating range.
• Networking Equipment - Serves as packet buffer memory in routers, switches, and communication modules where the 32M x 16 organization aligns well with data packet sizes and the 143MHz clock supports throughput requirements.
• Data Acquisition Systems - Provides temporary storage for sensor data and measurement systems, where the SDRAM's capacity and access speed enable buffering of high-resolution samples before processing or transmission.

Unique Advantages
