AS4C2M32S-6BCN

The AS4C2M32S-6BCN from Alliance Memory is a 64-megabit synchronous DRAM (SDRAM) organized as 2M x 32 bits. This high-density volatile memory device features an LVTTL interface and operates at clock frequencies up to 166 MHz with a fast 5.5ns access time, making it well-suited for embedded systems and computing applications requiring reliable, high-bandwidth memory.

Packaged in a compact 90-ball TFBGA (8x13mm) format, this SDRAM delivers excellent density-to-footprint ratio for space-constrained designs while maintaining compatibility with standard 3.3V system logic levels.

Key Features

• Memory Configuration - 64Mbit density organized as 2M x 32, providing a wide 32-bit data bus for efficient data transfers in single-access operations.
• High-Speed Performance - 166 MHz clock frequency with 5.5ns access time enables high-bandwidth memory operations for demanding embedded applications.
• LVTTL Interface - Low-voltage TTL compatibility allows direct connection to 3.3V logic systems without level translation circuitry.
• Flexible Voltage Supply - Operates from 3V to 3.6V supply voltage, accommodating typical 3.3V system rails with adequate margin.
• Compact BGA Package - 90-TFBGA (8x13mm) package provides high-density mounting for board space optimization.
• Commercial Temperature Range - Rated for operation from 0°C to 70°C, suitable for commercial and light industrial environments.

Typical Applications

• Embedded Computing Systems - The 2M x 32 organization and 166 MHz operation make this SDRAM well-suited for embedded processors and SoCs requiring dedicated high-bandwidth memory with a wide data path.
• Networking Equipment - Routers, switches, and network interface cards benefit from the fast access time and high clock rate for packet buffering and protocol processing applications.
• Industrial Control Panels - Human-machine interfaces (HMIs) and programmable logic controllers can utilize this memory for display buffering and program execution within the 0°C to 70°C operating range.
• Consumer Electronics - Set-top boxes, digital media players, and smart home devices leverage the compact TFBGA package and cost-effective 64Mbit density for system memory requirements.
