Overview of AS4C2M32D1-5BCN - 64Mbit DDR SDRAM
The AS4C2M32D1-5BCN is a 64Mbit synchronous dynamic random access memory (SDRAM) from Alliance Memory, Inc., organized as 2M x 32-bit and built on DDR (Double Data Rate) technology. This volatile memory solution operates at 200MHz clock frequency with 0.7ns access time, making it suitable for applications requiring moderate-speed data buffering and processing. With a compact 144-LFBGA package measuring 12mm x 12mm, it provides a space-efficient solution for embedded systems operating in standard commercial temperature ranges.
Key Features
- DDR SDRAM Architecture - Built on Double Data Rate technology with 2M x 32-bit memory organization, providing 64Mbit total capacity for efficient data storage and retrieval in embedded applications.
- 200MHz Clock Operation - Operates at 200MHz clock frequency with 0.7ns access time and 15ns write cycle time, delivering responsive performance for real-time data processing tasks.
- Low-Voltage Operation - Functions on 2.3V to 2.7V supply voltage, supporting power-efficient designs and compatibility with standard low-voltage logic systems.
- Parallel Memory Interface - Provides parallel interface for straightforward integration with microcontrollers, processors, and FPGA systems requiring direct memory access.
- Compact Package - Available in 144-LFBGA (12mm x 12mm) package, offering high pin density in a small footprint for space-constrained PCB layouts.
- Commercial Temperature Range - Rated for 0°C to 70°C ambient operation, suitable for indoor and climate-controlled equipment environments.
Typical Applications
- Consumer Electronics - This DDR SDRAM serves as working memory in set-top boxes, digital media players, and home automation controllers where moderate memory capacity supports user interface rendering and data buffering without excessive power consumption.
- Networking Equipment - The AS4C2M32D1-5BCN provides packet buffering and routing table storage in switches and routers operating in office or data center environments where the commercial temperature rating is sufficient and the parallel interface simplifies processor integration.
- Embedded Computing - This memory supports embedded processors in point-of-sale terminals, kiosks, and information displays where the 64Mbit capacity handles application code execution and temporary data storage efficiently.
- Industrial Controllers - In climate-controlled industrial settings, this SDRAM provides data memory for control systems, HMIs, and monitoring equipment that require reliable volatile storage for runtime operations.
Unique Advantages
- Established DDR Technology: Uses mature DDR SDRAM architecture with well-documented integration processes, reducing design risk and accelerating time-to-market for new products.
- Space-Efficient Footprint: The 144-LFBGA package delivers high pin count in minimal PCB area, allowing designers to allocate board space to other critical components.
- Simplified Parallel Interface: Direct parallel memory connection eliminates the need for serial protocol converters, reducing component count and simplifying firmware development.
- Low-Voltage Compatibility: 2.3V to 2.7V operation aligns with common system voltage rails, avoiding the need for dedicated voltage regulators and associated circuitry.
- Alliance Memory Sourcing: Alliance Memory specializes in legacy and long-lifecycle memory components, offering supply chain stability for designs requiring extended product availability.
Why Choose AS4C2M32D1-5BCN?
The AS4C2M32D1-5BCN is positioned for embedded systems and commercial equipment where 64Mbit DDR SDRAM capacity meets application requirements without over-specification. Its parallel interface and standard voltage operation simplify integration with existing processor platforms, while the compact BGA package supports miniaturized designs. Engineers should note the commercial temperature rating (0°C to 70°C) limits use to controlled environments, and the obsolete lifecycle status indicates this component may be better suited for maintenance of existing designs or short-production-run projects rather than new long-term platforms. For legacy system support or designs with established DDR SDRAM infrastructure, this component offers a straightforward memory solution with Alliance Memory's focus on sustained availability.
