The IS42S81600D-7TLI is a high-speed, low-power Dynamic Random Access Memory (DRAM) from Integrated Silicon Solution, Inc. (ISSI). It is a synchronous DRAM (SDRAM) organized as 8,388,608 words x 16 bits x 2 banks. This SDRAM is designed for memory-intensive applications requiring a large amount of volatile storage with fast access times.

Applications:

• Networking equipment: Routers, switches, and other network devices that require high-speed memory for packet buffering and processing.
• Graphics cards: Used as frame buffer memory in some graphics cards, especially in embedded or lower-end systems.
• Embedded systems: Various embedded applications that require fast and large memory capacity, such as industrial control systems, medical devices, and automotive systems.
• Printers and scanners: Used for image processing and buffering in printers and scanners.

Features:

• High-speed clock rate: Operates at a clock frequency up to 143 MHz, providing fast data access.
• Double data rate (DDR): Transfers data on both rising and falling edges of the clock signal, effectively doubling the data transfer rate.
• Low power consumption: Designed for low power operation, making it suitable for battery-powered devices and energy-efficient systems.
• Byte mask capability: Allows selective writing to individual bytes within a word.
• Self-refresh mode: Reduces power consumption when the device is not actively being accessed.
• Programmable burst length: Supports burst lengths of 1, 2, 4, 8, or full page.
• LVTTL compatible inputs: Compatible with standard LVTTL logic levels.

Benefits:

• Increased system performance: High-speed data access improves overall system performance.
• Reduced power consumption: Low power operation extends battery life in portable devices and reduces energy costs in other applications.
• Simplified system design: Compatible with standard logic levels, simplifying integration into existing systems.
• Flexible memory configuration: Programmable burst length and byte mask capability allows the user to customize the memory configuration to suit their application.
• Reliable operation: Designed for reliable operation in a wide range of environments.

Additional Details:

The IS42S81600D-7TLI operates from a 3.3V power supply. It is available in a TSOP (Thin Small Outline Package).
