Overview of AS4C4M32SA-6TINTR - 128Mbit Parallel SDRAM
The AS4C4M32SA-6TINTR from Alliance Memory, Inc. is a 128Mbit synchronous DRAM configured as 4M x 32 with a parallel interface. Built on proven SDRAM technology, this memory component delivers reliable performance for embedded systems, communications equipment, and industrial applications. With a 166MHz clock frequency and 5.4ns access time, it provides the speed and capacity needed for data buffering, temporary storage, and system memory expansion in applications requiring moderate bandwidth and wide data paths.
Key Features
- Memory Core - 128Mbit capacity organized as 4M x 32, providing a wide data bus suitable for parallel processing and high-throughput data transfer applications.
- Performance - 166MHz clock frequency with 5.4ns access time and 2ns write cycle time, enabling responsive memory operations for real-time embedded systems.
- Power Supply - Standard 3V to 3.6V operating voltage, compatible with common 3.3V system architectures.
- Temperature Range - Industrial-grade operating temperature range of -40°C to 85°C, suitable for harsh environments and demanding industrial applications.
- Package - 86-pin TSOP II form factor (0.400", 10.16mm width), a space-efficient surface-mount package that balances pin count with board space requirements.
Typical Applications
- Industrial Control Systems - This SDRAM serves as working memory in PLCs, motion controllers, and industrial PCs where the extended temperature range ensures reliable operation in factory floor environments.
- Network Equipment - Provides packet buffering and routing table storage in switches, routers, and network appliances where the 32-bit wide data path supports efficient data handling.
- Embedded Computing - Functions as main system memory or frame buffer in embedded processors and SBCs where moderate capacity and proven SDRAM architecture simplify integration.
- Test and Measurement Instruments - Enables data acquisition buffering and waveform storage in oscilloscopes, logic analyzers, and data loggers where industrial temperature tolerance supports field deployment.
Unique Advantages
- Wide Data Bus: The 32-bit organization reduces the number of memory devices needed for systems requiring parallel data access, simplifying board layout.
- Industrial Temperature Tolerance: Extended -40°C to 85°C operation eliminates the need for additional thermal management in many industrial environments.
