IS42S32400B-6BL-TR

The IS42S32400B-6BL-TR from ISSI is a 128-megabit synchronous dynamic RAM (SDRAM) organized as 4 million words by 32 bits. This parallel-interface volatile memory operates at a clock frequency of 166MHz with an access time of 5.4ns, making it suitable for applications requiring fast data throughput. Designed for consumer and commercial systems, this DRAM provides cost-effective memory expansion in a compact 90-pin TFBGA package.

Key Features

• Memory Architecture - 128Mbit capacity organized as 4M x 32, providing efficient word-level access for 32-bit data bus systems.
• Performance - 166MHz clock frequency with 5.4ns access time enables rapid data retrieval for bandwidth-intensive applications.
• Power Supply - Operates on standard 3V to 3.6V supply voltage, compatible with common embedded system power rails.
• Package - 90-pin TFBGA measuring 8mm x 13mm delivers high density while minimizing board space requirements.
• Temperature Range - Commercial temperature range of 0°C to 70°C suits standard operating environments.

Typical Applications

• Consumer Electronics - This SDRAM serves as main system memory in set-top boxes and digital media players where the 166MHz speed supports video processing and user interface responsiveness.
• Networking Equipment - In routers and switches operating in controlled environments, the parallel interface provides buffer memory for packet processing at wire speeds.
• Office Equipment - Printers and multifunction devices use this memory for image buffering and document processing, where the 128Mbit capacity handles moderate-resolution graphics.
• Embedded Computing - Single-board computers and embedded controllers leverage the 32-bit organization for efficient data handling in commercial applications.
