Overview of AS4C32M16SC-7TINTR - 512Mbit Synchronous DRAM

The AS4C32M16SC-7TINTR is a 512Mbit synchronous dynamic random access memory (SDRAM) from Alliance Memory, Inc. organized as 32M x 16 bits. Operating at 133MHz with a 7ns access time, this parallel interface DRAM provides reliable, cost-effective volatile memory for embedded systems, industrial equipment, and consumer electronics requiring moderate density and standard voltage operation.

Key Features

  • Memory Configuration - 512Mbit total capacity organized as 32 million words by 16 bits, providing flexible data width for efficient system integration.
  • Performance Specifications - 133MHz clock frequency with 7ns access time and 6.7ns write cycle time delivers responsive read and write operations for real-time applications.
  • Power Supply - Standard 3V to 3.6V operating voltage simplifies integration with mainstream 3.3V logic systems and reduces power conversion complexity.
  • Extended Temperature Range - Industrial-grade -40°C to 85°C operating temperature ensures reliable performance across harsh environmental conditions.
  • Package Format - 54-pin TSOP II package with 10.16mm width offers a compact footprint suitable for space-constrained PCB designs.
  • Technology Platform - SDRAM technology provides synchronous operation with system clocks for predictable timing and simplified controller design.

Typical Applications

  • Industrial Automation - This SDRAM provides working memory for programmable logic controllers (PLCs), human-machine interfaces (HMIs), and motion control systems where the extended temperature range ensures consistent operation in factory floor environments.
  • Embedded Computing Systems - The 32M x 16 organization matches common microprocessor and microcontroller data bus widths, making it well-suited for buffering, program execution space, and data processing in embedded designs.
  • Telecommunications Equipment - In routers, switches, and base station controllers, this SDRAM handles packet buffering and protocol processing tasks where moderate density and reliable operation are essential.
  • Medical Instrumentation - Diagnostic equipment, patient monitors, and imaging systems benefit from the stable performance across temperature variations and the parallel interface for straightforward integration with legacy architectures.
  • Consumer Electronics - Set-top boxes, digital displays, and multimedia devices utilize this DRAM for frame buffering, user interface responsiveness, and temporary data storage where cost-effectiveness matters.

Unique Advantages

  • Proven SDRAM Architecture: Synchronous operation eliminates complex asynchronous timing considerations, reducing design validation time and improving system reliability.
  • Industrial Temperature Qualification: -40°C to 85°C rating reduces the need for active cooling in industrial enclosures and extends operating range beyond commercial-grade alternatives.
  • Standard Voltage Compatibility: 3.3V operation integrates directly with widespread logic families without level shifters, simplifying power supply design and reducing BOM cost.
  • Compact Physical Footprint: The 54-TSOP II package balances pin count with board space efficiency, supporting higher density PCB layouts than larger packages.
  • Established Technology Node: Mature SDRAM technology offers stable supply, predictable behavior, and extensive controller IP availability across multiple vendor ecosystems.
  • Tape and Reel Packaging: TR suffix indicates tape and reel format optimized for automated pick-and-place assembly, reducing handling costs in volume production.

Why Choose AS4C32M16SC-7TINTR?

The AS4C32M16SC-7TINTR addresses designs requiring moderate-density volatile memory with industrial temperature tolerance and straightforward parallel interfacing. The 512Mbit capacity and 32M x 16 organization provide sufficient working memory for many real-time embedded applications while maintaining compatibility with 16-bit processor architectures. The standard 3.3V supply voltage and synchronous operation simplify integration with existing designs.
