Overview of AS4C32M16SB-7TIN - 512Mb SDRAM with Industrial Temperature Range

The AS4C32M16SB-7TIN is a 512Mb Synchronous DRAM (SDRAM) from Alliance Memory, organized as 32M x 16 bits. This parallel-interface memory device operates at clock frequencies up to 143MHz with a fast 5.4ns access time, making it suitable for embedded systems requiring reliable high-speed memory access.

Designed for industrial applications, this SDRAM features an extended operating temperature range of -40°C to 85°C and operates from a 3V to 3.6V supply voltage, providing flexibility for a wide range of system designs.

Key Features

  • Memory Configuration - 512Mb density organized as 32M x 16 bits, providing efficient 16-bit data bus width for embedded processor interfaces.
  • High-Speed Performance - Supports clock frequencies up to 143MHz with 5.4ns access time and 14ns write cycle time for responsive system operation.
  • Industrial Temperature Range - Operates reliably from -40°C to 85°C, enabling deployment in demanding industrial environments.
  • Standard Voltage Operation - 3V to 3.6V supply voltage range compatible with common embedded system power rails.
  • Compact Package - 54-TSOP II package with 0.400" (10.16mm) width provides a surface-mount solution with established PCB footprint compatibility.

Typical Applications

  • Industrial Control Systems - This SDRAM provides reliable memory for PLCs, industrial computers, and automation equipment where the extended -40°C to 85°C temperature range ensures consistent operation in factory and outdoor environments.
  • Embedded Computing - The 32M x 16 organization and 143MHz clock speed support embedded processors and SoCs requiring high-bandwidth parallel memory interfaces for data buffering and program execution.
  • Telecommunications Equipment - Network switches, routers, and communication modules benefit from the fast 5.4ns access time for packet buffering and protocol processing applications.
  • Test and Measurement Instruments - Data acquisition systems and measurement equipment utilize this SDRAM for sample buffering where industrial temperature tolerance ensures accuracy across varying environmental conditions.

Unique Advantages

  • Extended Temperature Operation: The -40°C to 85°C range eliminates the need for thermal management in many industrial applications, reducing system complexity and cost.
  • Industry-Standard Footprint: The 54-TSOP II package enables drop-in compatibility with existing designs using standard SDRAM pinouts.
  • Optimized Access Timing: 5.4ns access time enables efficient memory subsystem design with reduced wait states for processor interfaces.
  • Single Supply Design: 3V to 3.6V operation simplifies power supply design by aligning with common embedded system voltage rails.
  • Active Lifecycle Status: Currently in active production, ensuring long-term availability for product designs requiring extended manufacturing support.
