IS42S32400F-7TL-TR

The IS42S32400F-7TL-TR is a 128-megabit synchronous DRAM (SDRAM) from ISSI, organized as 4M x 32 for efficient parallel data access. This device operates at a clock frequency up to 143 MHz with a 5.4 ns access time, making it suitable for embedded systems and computing applications that require fast, cost-effective volatile memory. With a 3V to 3.6V supply voltage and 0°C to 70°C operating temperature range, this SDRAM provides reliable performance for commercial-grade designs.

Key Features

• Memory Architecture - 128Mbit capacity organized as 4M x 32, providing a wide 32-bit parallel interface for high-bandwidth data transfers in a single memory device.
• High-Speed Operation - Supports clock frequencies up to 143 MHz with 5.4 ns access time, enabling fast read and write cycles for time-sensitive applications.
• Standard SDRAM Technology - Volatile synchronous DRAM provides predictable timing characteristics and simplified interface design compared to asynchronous memory types.
• Power Supply - Operates from a single 3V to 3.6V supply, compatible with standard 3.3V system designs and reducing power supply complexity.
• Commercial Temperature Range - Rated for 0°C to 70°C ambient operation, suitable for indoor commercial and consumer electronic equipment.
• Industry-Standard Package - Available in 86-pin TSOP II package (10.16mm width), a widely adopted form factor for embedded memory solutions.

Typical Applications

• Embedded Computing Systems - This SDRAM serves as working memory for microprocessors and microcontrollers in set-top boxes, point-of-sale terminals, and other commercial computing devices where its 32-bit wide bus matches processor architectures and its speed supports real-time operation.
• Consumer Electronics - Provides volatile storage for digital TVs, home networking equipment, and multimedia devices where the 128Mbit capacity and fast access times support video buffering and user interface responsiveness.
• Telecommunications Equipment - Functions as buffer memory in routers, switches, and VoIP phones where the synchronous interface simplifies timing design and the parallel organization enables efficient packet processing.
• Industrial Control Panels - Supports HMI displays and operator interface terminals in commercial-grade industrial applications within the 0°C to 70°C temperature range, providing memory for graphical interfaces and data logging.

Unique Advantages

• Wide 32-bit Bus Reduces Component Count: The 4M x 32 organization eliminates the need for multiple narrower memory devices in 32-bit systems, simplifying PCB layout and reducing BOM costs.
• Synchronous Interface Simplifies Timing Design: SDRAM's clock-synchronous operation provides more predictable timing than asynchronous DRAM, reducing design complexity and improving signal integrity.
• Standard 3.3V Operation: Compatibility with widely used 3.3V logic levels eliminates the need for level shifters and reduces power supply requirements compared to 5V legacy memory.
• Proven TSOP II Package: The industry-standard 86-TSOP II package provides a balance of density and ease of assembly, with established manufacturing processes and inspection methods.
• Commercial Temperature Rating: The 0°C to 70°C specification matches the requirements for indoor commercial and consumer applications without the cost premium of extended or industrial temperature grades.
• 143 MHz Clock Support: The device's speed grade supports system clock frequencies that balance performance with power consumption for mainstream embedded applications.
