IS42S16320F-7TL 512Mb SDRAM, 143 MHz synchronous DRAM, TSOP II SDRAM
The IS42S16320F-7TL from Integrated Silicon Solution Inc (ISSI) is a high-speed 512Mb (16Mx32) Synchronous DRAM (SDRAM) designed for embedded systems, networking equipment, and consumer electronics. Operating at a clock frequency of 143 MHz (7ns cycle time), it delivers high bandwidth data transfer with low power consumption, making it ideal for real-time processing and multimedia applications. The device features a fully synchronous pipeline architecture, burst read/write operations, and auto refresh/self refresh modes for efficient memory management. With a single 3.3V power supply and LVTTL-compatible I/O, it ensures seamless integration with FPGAs, processors, and ASICs. Packaged in a compact 54-pin TSOP II, it is optimized for space-constrained PCB designs.
ISSI 32-bit memory chip IS42S16320F Key Features
● High-Speed Operation: 143 MHz clock frequency for fast data access.
● Large Capacity: 512Mb (16M words × 32 bits) organization.
● Low Power Consumption: Auto power-down and self-refresh modes for energy efficiency.
● Burst Mode Support: Programmable burst lengths (1, 2, 4, 8, full page) for optimized data throughput.
● Wide Compatibility: 3.3V LVTTL I/O for easy interfacing with modern processors.
● Reliable Refresh: 4,096 refresh cycles every 64 ms to maintain data integrity.
● Compact Packaging: 54-pin TSOP II (400 mil width) for high-density layouts.
Applications
The IS42S16320F-7TL is widely used in digital TVs, set-top boxes, routers, industrial automation controllers, and medical imaging devices. Its high-speed data transfer suits video buffering, graphics rendering, and network packet processing, while its low-power modes make it suitable for battery-backed or always-on systems.
Selection Advantages
This SDRAM stands out for its balance of speed, capacity, and power efficiency. Unlike lower-density memories, it reduces the need for multiple chips in 32-bit bus systems, simplifying PCB design. The burst mode and pipeline architecture enhance performance in sequential data access applications, while the TSOP II package ensures compatibility with standard SDRAM sockets. Its industrial-grade temperature range (-40°C to +85°C) guarantees reliability in harsh environments.
