Overview of AS4C32M16SA-7BCNTR - 512Mbit Parallel SDRAM
The AS4C32M16SA-7BCNTR is a 512Mbit synchronous dynamic random access memory (SDRAM) from Alliance Memory, Inc. This parallel SDRAM features a 32M x 16 memory organization and operates at clock frequencies up to 143MHz with a 5.4ns access time. Designed for embedded systems and industrial applications requiring reliable, cost-effective volatile memory, this DRAM offers straightforward integration through its parallel interface and standard 3.3V operation.
Key Features
- Memory Architecture - 512Mbit total capacity organized as 32 million words by 16 bits, providing flexible data storage for embedded applications.
- Performance Specifications - 143MHz maximum clock frequency with 5.4ns access time and 2ns write cycle time ensures responsive data transfer for real-time systems.
- Power Supply - Single 3.3V supply voltage (3V to 3.6V range) simplifies power distribution and reduces component count in system designs.
- Parallel Interface - Standard parallel memory interface enables direct connection to microprocessors and controllers without additional protocol conversion.
- Package Options - Compact 54-pin FBGA package (8mm x 8mm) minimizes board space while maintaining reliable signal integrity.
- Temperature Range - Commercial temperature grade (0°C to 70°C) supports typical indoor and controlled environment applications.
Typical Applications
- Embedded Computing - This SDRAM serves as main memory or frame buffer in embedded processors and microcontrollers where the parallel interface provides direct, high-speed access to stored data without protocol overhead.
- Industrial Control Systems - The 0°C to 70°C operating range makes this memory suitable for programmable logic controllers (PLCs) and human-machine interfaces (HMIs) in climate-controlled industrial facilities.
- Consumer Electronics - This DRAM supports set-top boxes, digital displays, and multimedia devices where moderate performance requirements are balanced with cost-effective memory solutions.
- Legacy System Support - The parallel SDRAM architecture provides direct replacement capability for aging systems requiring compatible memory components to extend product lifecycles.
Unique Advantages
- Simplified Integration: The parallel interface eliminates the need for memory controllers or translation logic, reducing design complexity and development time.
- Standard Form Factor: Industry-standard pinout and package configuration enable drop-in compatibility with existing board layouts and reduce qualification time.
- Cost-Effective Solution: Mature SDRAM technology provides reliable volatile memory at competitive pricing for applications not requiring cutting-edge performance.
- Single Voltage Operation: 3.3V-only power requirement reduces power supply complexity and component count compared to dual-voltage architectures.
- Compact Footprint: The 8mm x 8mm FBGA package conserves board space while supporting sufficient capacity for embedded applications.
