AS4C4M16D1A-5TCN

The AS4C4M16D1A-5TCN from Alliance Memory is a 64Mbit DDR SDRAM organized as 4M x 16 bits, delivering high-speed parallel memory access for embedded systems and computing applications. This DDR1 memory device operates at 200MHz clock frequency with 0.7ns access time, providing the bandwidth needed for data-intensive applications.

Housed in a 66-TSOP II package with 10.16mm width, this SDRAM offers a balance of performance and board space efficiency for designs requiring reliable volatile memory storage.

Key Features

• Memory Architecture - 64Mbit capacity organized as 4M x 16 bits, providing 16-bit wide data bus for efficient parallel data transfer.
• DDR SDRAM Technology - Double data rate operation enables data transfer on both clock edges, effectively doubling throughput compared to single data rate SDRAM.
• High-Speed Performance - 200MHz clock frequency with 0.7ns access time supports demanding memory bandwidth requirements.
• Low Voltage Operation - 2.3V to 2.7V supply voltage range reduces power consumption while maintaining compatibility with standard DDR1 voltage levels.
• Commercial Temperature Range - Operates from 0°C to 70°C, suitable for indoor and controlled environment applications.
• 66-TSOP II Package - Industry-standard thin small outline package provides reliable surface mount assembly with proven manufacturing processes.

Typical Applications

• Networking Equipment - This DDR SDRAM provides packet buffering and routing table storage in switches and routers where the 200MHz operation supports wire-speed data processing.
• Industrial Control Systems - The 64Mbit capacity and parallel interface enable program and data storage in PLCs and embedded controllers requiring deterministic memory access.
• Consumer Electronics - Set-top boxes, digital media players, and similar devices benefit from the cost-effective memory density and standard DDR1 interface compatibility.
