Overview of MT48LC4M32B2TG-6A IT:L - 128Mbit Parallel SDRAM
The MT48LC4M32B2TG-6A IT:L is a 128-megabit synchronous dynamic random access memory (SDRAM) from Alliance Memory, Inc. This parallel-interface DRAM features a 4M x 32 memory organization, operating at clock frequencies up to 167 MHz with a 5.4ns access time. Designed for industrial temperature environments ranging from -40°C to 85°C, this SDRAM delivers reliable volatile memory storage for embedded systems requiring high-bandwidth data access.
Built on proven SDRAM technology and supplied in a compact 86-TSOP II package, this device offers a practical memory solution for space-constrained applications requiring 32-bit parallel data paths and extended temperature operation.
Key Features
- Memory Architecture - 128-megabit capacity organized as 4 million words by 32 bits, providing efficient data access for 32-bit processors and controllers.
- Performance - 167 MHz clock frequency with 5.4ns access time enables fast data throughput for demanding embedded applications, while 12ns write cycle time supports rapid sequential operations.
- Power Supply - Single 3V to 3.6V operating voltage simplifies power distribution and aligns with common embedded system power rails.
- Temperature Range - Industrial-grade -40°C to 85°C ambient temperature tolerance ensures reliable operation in harsh environmental conditions.
- Package - 86-pin TSOP II surface-mount package with 10.16mm width provides a balance between pin count, board space, and manufacturability.
Typical Applications
- Industrial Controllers - This SDRAM provides working memory for programmable logic controllers (PLCs), human-machine interfaces (HMIs), and industrial PCs where the extended temperature range ensures consistent performance in factory floor environments.
- Embedded Computing Systems - The 32-bit wide data path and 167 MHz operation make this device suitable for embedded processors and DSPs requiring high-bandwidth memory access for real-time data processing and buffering.
- Communications Infrastructure - Networking equipment and telecommunications systems benefit from the fast access times and parallel interface for packet buffering, routing tables, and protocol processing in routers and switches.
- Test and Measurement Equipment - Instruments requiring temporary data storage for waveform capture, signal analysis, or measurement buffering utilize the SDRAM's combination of capacity and speed to handle high-sample-rate data streams.
Unique Advantages
- Proven Technology Platform: SDRAM architecture offers mature, well-understood performance characteristics that simplify system design and reduce integration risks compared to newer memory technologies.
- Extended Temperature Tolerance: The -40°C to 85°C operating range eliminates the need for thermal management in many industrial and outdoor installations, reducing system complexity and cost.
- Direct Parallel Interface: Native parallel connectivity to processors and controllers avoids the complexity and latency of serial memory interfaces, streamlining PCB layout and improving deterministic response.
- Flexible Memory Organization: The 4M x 32 configuration naturally aligns with 32-bit processor architectures, minimizing external logic and enabling efficient single-cycle accesses for word-sized data.
- Compact Surface-Mount Package: The 86-TSOP II form factor provides a standardized footprint compatible with automated assembly processes while maintaining a reasonable board space requirement.
