AS4C4M16D1A-5TIN

The AS4C4M16D1A-5TIN from Alliance Memory is a 64-megabit DDR SDRAM organized as 4M x 16 bits. This synchronous DRAM utilizes double data rate architecture to deliver high-bandwidth memory performance for embedded and industrial applications.

With a 200MHz clock frequency and 0.7ns access time, this memory IC provides the throughput needed for data-intensive processing while maintaining compatibility with standard DDR interfaces.

Key Features

• DDR SDRAM Architecture - Double data rate technology transfers data on both rising and falling clock edges, effectively doubling bandwidth compared to single data rate SDRAM at the same clock frequency.
• 64Mbit Density in 4M x 16 Organization - Provides 4 million 16-bit words of volatile storage, suitable for applications requiring moderate memory capacity with wide data bus access.
• 200MHz Clock Operation - Supports clock speeds up to 200MHz, enabling 400MT/s effective data rate for demanding embedded applications.
• Extended Temperature Range - Operates from -40°C to 85°C, making it suitable for industrial environments where standard commercial temperature ratings are insufficient.
• Low Voltage Operation - Functions with supply voltage from 2.3V to 2.7V, supporting battery-powered and power-sensitive designs.
• 66-TSOP II Package - Industry-standard 66-pin TSOP II package with 10.16mm width provides a compact footprint while maintaining ease of PCB assembly and rework.

Typical Applications

• Industrial Control Systems - This DDR SDRAM provides reliable program and data storage for PLCs, motion controllers, and automation equipment where the extended temperature range ensures stable operation in factory floor environments.
• Networking Equipment - Routers, switches, and network appliances benefit from the high bandwidth and parallel interface for packet buffering and routing table storage.
• Embedded Computing - Single-board computers and embedded processors use this memory for main system RAM where cost-effective DDR performance is required.
• Point-of-Sale Terminals - Retail and commercial terminals utilize this SDRAM for application execution and transaction processing in environments with varying temperature conditions.

Unique Advantages

• Industrial Temperature Qualified: The -40°C to 85°C operating range eliminates the need for thermal management in harsh environments, reducing system complexity and cost.
• Active Lifecycle Status: Ongoing production availability provides supply chain stability for long-lifecycle industrial and embedded designs.
• Parallel Memory Interface: Standard parallel DDR interface simplifies integration with existing memory controller designs without requiring specialized SerDes or PHY components.
• Fast Access Time: The 0.7ns access time supports low-latency memory operations critical for real-time embedded applications.
• Pin-Compatible Form Factor: The 66-TSOP II package follows industry-standard pinouts, enabling second-source options and design flexibility.
