AS4C2M32S-7TCNTR

The AS4C2M32S-7TCNTR from Alliance Memory is a 64-megabit synchronous DRAM (SDRAM) organized as 2M x 32. This parallel-interface memory IC delivers reliable volatile storage for embedded systems and computing applications requiring fast, synchronous memory access. With a 143MHz clock frequency and 5.5ns access time, this SDRAM provides responsive data handling for time-sensitive operations.

Key Features

• Memory Architecture - 64Mbit capacity organized as 2M x 32, providing a 32-bit wide data path for efficient parallel data transfer.
• Performance - 143MHz clock frequency with 5.5ns access time and 2ns write cycle time enables fast synchronous operation for responsive system performance.
• Power Supply - Operates on a standard 3V to 3.6V supply voltage, compatible with common embedded system power rails.
• Operating Temperature - Rated for 0°C to 70°C (TA) commercial temperature range, suitable for standard indoor environments.
• Package - Available in 86-TSOP II package with 10.16mm width, providing a compact footprint for space-constrained designs.

Typical Applications

• Embedded Computing Systems - This SDRAM serves as main memory or frame buffer in embedded processors and controllers where the 32-bit wide interface provides efficient data throughput for program execution and data processing.
• Communications Equipment - The synchronous interface and fast access time make this memory suitable for networking devices and telecommunications equipment that require predictable, low-latency memory operations.
• Legacy System Maintenance - As an obsolete component, this SDRAM provides replacement inventory for maintaining existing designs and extending the operational life of deployed systems.

Unique Advantages

• Standard SDRAM Interface: Simplifies integration with legacy processor and controller architectures that rely on parallel SDRAM interfaces.
• 32-bit Data Width: Reduces the number of memory devices needed in 32-bit bus architectures compared to narrower memory configurations.
• Proven Technology: SDRAM architecture provides well-understood timing characteristics and broad ecosystem support for system design.
• Compact TSOP Package: Enables higher board-level density compared to larger through-hole or wider surface-mount packages.

Why Choose AS4C2M32S-7TCNTR?

The AS4C2M32S-7TCNTR is positioned for system maintenance and legacy design support. While this component carries an obsolete lifecycle status, it provides critical memory functionality for extending the operational life of existing systems where design changes are not practical. The 32-bit organization and synchronous operation align well with embedded processors and controllers from the era when parallel SDRAM was the dominant memory technology.

For new designs, consider current-generation memory technologies that offer improved performance, lower power consumption, and active lifecycle status. However, for maintaining fielded systems or supporting long-term production commitments, securing inventory of this SDRAM helps ensure continuity of operations.
