AS4C32M16SB-7TINTR

The AS4C32M16SB-7TINTR is a 512Mbit 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 applications requiring reliable, high-speed volatile memory.

Designed for industrial environments, this SDRAM supports an extended operating temperature range of -40°C to 85°C and operates from a 3V to 3.6V supply voltage. The device is housed in a 54-TSOP II package with 0.400" (10.16mm) width.

Key Features

• Memory Capacity and Organization - 512Mbit total capacity organized as 32M x 16, providing efficient word-width access for 16-bit data buses.
• High-Speed Performance - 143MHz clock frequency with 5.4ns access time and 14ns write cycle time enables responsive memory operations.
• Industrial Temperature Support - Operating range of -40°C to 85°C ensures reliable performance in demanding industrial environments.
• Parallel Interface - Standard parallel SDRAM interface provides straightforward integration with existing memory controllers and bus architectures.
• Low Voltage Operation - 3V to 3.6V supply voltage reduces power consumption compared to 5V alternatives.
• Industry-Standard Package - 54-TSOP II package offers a proven, widely-supported footprint for PCB design.

Typical Applications

• Industrial Automation Systems - This SDRAM provides dependable volatile memory for PLCs, HMIs, and industrial controllers where the extended temperature range ensures consistent operation in factory floor environments with temperature fluctuations.
• Embedded Computing - The 32M x 16 organization and parallel interface make this device well-suited for embedded processors and SoCs requiring external SDRAM for program execution and data buffering.
• Networking Equipment - Routers, switches, and network appliances benefit from the fast access times for packet buffering and routing table storage in temperature-variable deployment locations.
• Test and Measurement Instruments - The combination of speed and industrial temperature rating supports data acquisition systems and measurement equipment operating in lab and field conditions.

Unique Advantages

• Extended Temperature Reliability: The -40°C to 85°C operating range eliminates concerns about memory failures in environments where commercial-grade components would be insufficient.
• Drop-In Compatibility: Standard SDRAM interface and 54-TSOP II package allow straightforward replacement or second-sourcing in existing designs.
• Balanced Price-Performance: 512Mbit density at 143MHz provides adequate capacity and speed for many industrial applications without over-specifying.
• Active Product Status: Current production status ensures long-term availability for ongoing manufacturing requirements.
• Simplified Design Integration: Single 3V to 3.6V supply rail reduces power supply complexity compared to multi-voltage memory solutions.
