• Temperature Range - Extended -40°C to 85°C ambient operating range supports industrial and harsh environment deployments.
• Write Cycle Performance - 12ns write cycle time ensures efficient data throughput for memory-intensive operations.

Typical Applications

• Industrial Automation - This SDRAM provides working memory for programmable logic controllers (PLCs) and human-machine interfaces (HMIs) where the extended temperature tolerance ensures reliable operation in factory floor environments with variable thermal conditions.
• Embedded Computing Systems - The parallel interface and 166MHz operation make this device suitable for embedded processors and microcontrollers that require synchronous DRAM for program execution and data buffering in legacy system upgrades or cost-sensitive designs.
• Telecommunications Equipment - Used in routers, switches, and base stations where the 256Mbit density provides adequate buffer memory for packet processing and the industrial temperature range supports equipment deployed in outdoor cabinets or uncontrolled environments.
• Test and Measurement Instruments - The device serves as data acquisition buffer memory in oscilloscopes, spectrum analyzers, and data loggers where reliable volatile storage is needed for waveform capture and signal processing operations.
• Legacy System Maintenance - Provides drop-in memory replacement for aging industrial and commercial equipment originally designed around SDRAM technology, extending the service life of fielded systems.

Unique Advantages

• Industry-Standard Footprint: The 54-TSOP II package matches common SDRAM layouts, enabling straightforward PCB integration and compatibility with existing board designs.
• Simplified Power Design: Single-voltage 3.3V operation eliminates the need for multiple power rails, reducing BOM cost and board space requirements.
• Extended Environmental Capability: Industrial-grade -40°C to 85°C temperature range eliminates the need for thermal management in many applications, reducing system complexity.
• Proven SDRAM Architecture: Mature synchronous DRAM technology provides predictable timing characteristics and well-documented interface specifications for straightforward firmware development.
• Parallel Interface Compatibility: Direct connection to legacy processor buses without protocol translation or bridging components simplifies migration from older memory technologies.
• Density and Organization Balance: 16M x 16 configuration aligns with common 16-bit and 32-bit data path widths in industrial and embedded controllers.

Why Choose AS4C16M16S-6TIN?

This synchronous DRAM is positioned for industrial and embedded applications where proven parallel memory technology, extended temperature operation, and straightforward integration are priorities.
