AS4C2M32S-6BIN

The AS4C2M32S-6BIN is a 64Mbit synchronous DRAM (SDRAM) from Alliance Memory, organized as 2M x 32 bits. This parallel interface memory device operates at clock frequencies up to 166MHz with 5.4ns access time, providing high-bandwidth data transfer for embedded systems.

Designed for industrial applications, this SDRAM operates across an extended temperature range of -40°C to 85°C, making it suitable for demanding environments where standard commercial memory would not suffice.

Key Features

• Memory Configuration - 64Mbit density organized as 2M x 32, providing a wide 32-bit data bus that reduces the need for multiple memory devices in parallel configurations.
• High-Speed Operation - 166MHz clock frequency with 5.4ns access time and 2ns write cycle time enables efficient data throughput for performance-critical applications.
• Industrial Temperature Support - Full operation from -40°C to 85°C (TA) ensures reliable performance in harsh industrial, outdoor, and transportation environments.
• Standard Voltage Operation - 3V to 3.6V supply voltage provides compatibility with common 3.3V system designs while offering voltage margin for noise immunity.
• Compact Package - 90-TFBGA (8x13mm) package offers a small footprint for space-constrained designs while maintaining excellent thermal characteristics.

Typical Applications

• Industrial Automation - This SDRAM provides reliable memory for PLCs, HMI systems, and industrial controllers where the extended temperature range ensures consistent operation in factory floor environments with varying thermal conditions.
• Embedded Systems - The 32-bit wide data bus and 166MHz operation make this device well-suited for embedded processors requiring high memory bandwidth without the complexity of multiple parallel memory chips.
• Telecommunications Equipment - Network switches, routers, and communication modules benefit from the fast access times and industrial temperature rating for equipment deployed in outdoor or unconditioned spaces.
• Transportation Systems - Railway signaling, vehicle telematics, and fleet management systems can rely on this SDRAM's industrial temperature range to maintain data integrity across seasonal temperature extremes.

Unique Advantages

• Simplified Board Design: The 32-bit data bus width reduces component count compared to using multiple narrower memory devices, simplifying PCB layout and reducing BOM cost.
• Active Product Status: Currently in active production, ensuring long-term availability for designs requiring extended product lifecycles.
• Drop-In Compatibility: Standard SDRAM interface and pinout enables straightforward integration with existing designs and commonly available memory controllers.
• Extended Operating Range: The -40°C to 85°C temperature specification exceeds commercial-grade requirements, providing design margin for products that may encounter temperature extremes.
• Compact Form Factor: The 90-TFBGA package maximizes board space efficiency while providing reliable solder connections suitable for industrial manufacturing processes.
