Overview of IS42S16800F-7TLI-TR - 128Mbit Parallel SDRAM
The IS42S16800F-7TLI-TR is a 128-megabit synchronous dynamic random access memory (SDRAM) device organized as 8M x 16. Built on proven DRAM technology, this parallel interface memory provides fast data access with a 5.4ns access time and 143MHz clock frequency. Designed for embedded systems and industrial applications, it delivers reliable volatile memory storage with extended temperature tolerance from -40°C to 85°C.
Key Features
- Memory Configuration - 128Mbit density organized as 8M words by 16 bits, providing flexible memory architecture for word-oriented processing applications.
- High-Speed Operation - 143MHz clock frequency with 5.4ns access time enables rapid data retrieval for time-sensitive embedded applications.
- Standard Voltage Operation - 3V to 3.6V supply voltage range ensures compatibility with common 3.3V logic systems while minimizing power consumption.
- Extended Temperature Range - Rated for -40°C to 85°C ambient operation, making it suitable for industrial environments beyond standard commercial temperature specifications.
- Industry-Standard Package - 54-pin TSOP II package with 10.16mm width provides space-efficient board mounting with established manufacturing compatibility.
- Parallel Interface - Direct memory bus connection simplifies integration with microcontrollers and processors requiring external memory expansion.
Typical Applications
- Industrial Control Systems - This SDRAM serves as program execution space and data buffering in PLCs and industrial controllers where the extended temperature range ensures reliable operation in factory floor environments.
- Embedded Computing Platforms - Provides main system memory or frame buffer storage for single-board computers and embedded processors that require external DRAM with parallel interface connectivity.
- Data Acquisition Systems - Functions as high-speed data capture buffer in measurement instruments and data loggers where the 143MHz operation supports rapid sampling rates.
- Networking Equipment - Supplies packet buffering and routing table storage in switches and routers operating in industrial network environments with extended temperature requirements.
- Legacy System Support - Offers drop-in memory replacement for existing designs using parallel SDRAM architecture, enabling continued production and field service of established equipment.
Unique Advantages
- Proven Technology Foundation: SDRAM architecture delivers predictable performance characteristics with decades of field-proven reliability in demanding applications.
- Simplified Design Integration: Standard parallel interface eliminates the need for complex serial protocol handling or memory controller adaptations required by newer memory technologies.
- Industrial Temperature Capability: Extended -40°C to 85°C specification reduces system-level thermal management requirements and supports deployment in harsh operating conditions.
- Established Supply Chain: TSOP II packaging uses widely available manufacturing processes and test equipment, supporting high-volume production and field replacement availability.
- Straightforward Procurement: Tape and reel packaging (indicated by -TR suffix) facilitates automated assembly processes and inventory management for production environments.
- Cost-Effective Memory Solution: Mature DRAM technology and standard packaging provide economical memory density for applications where newer high-density memory formats exceed performance requirements.
Why Choose IS42S16800F-7TLI-TR?
This SDRAM module represents a practical choice for industrial and embedded system designs requiring proven parallel memory technology with extended temperature operation. The 128Mbit density addresses common memory requirements in control systems, data acquisition, and legacy equipment support applications without the complexity of serial memory interfaces or advanced high-speed memory protocols. Note that this component carries an Obsolete lifecycle status, so designers should confirm availability for their production timeline and consider it primarily for existing design support, field service, or applications with established inventory.
The combination of industrial temperature rating, standard 3.3V operation, and conventional TSOP II packaging makes this device well-suited for designs prioritizing compatibility with existing infrastructure and manufacturing processes over cutting-edge density or bandwidth specifications.
