MT48LC16M16A2F4-6A:GTR

The MT48LC16M16A2F4-6A:GTR from Alliance Memory is a 256-megabit synchronous DRAM designed for applications requiring high-speed parallel memory access. Built on proven SDRAM technology, this device organizes 256 million bits as 16M x 16 and operates at clock frequencies up to 167 MHz with a 5.4 ns access time. It delivers reliable performance for embedded systems, networking equipment, and industrial applications where volatile memory with straightforward parallel interfacing is essential.

Key Features

• Memory Core: 256Mbit capacity organized as 16M x 16, providing flexible data path width for word-oriented applications.
• High-Speed Operation: Supports clock frequencies up to 167 MHz with 5.4 ns access time, enabling fast read and write operations for time-sensitive applications.
• Parallel Interface: Standard parallel memory interface simplifies integration with microcontrollers, FPGAs, and processors requiring direct memory connections.
• Power Supply: Operates from a single 3V to 3.6V supply, compatible with standard 3.3V system designs.
• Package: 54-pin VFBGA (8x8mm) offers a compact footprint for space-constrained designs.
• Operating Temperature: Rated for 0°C to 70°C (TA), suitable for commercial and standard industrial environments.

Typical Applications

• Networking Equipment - This SDRAM serves as buffer memory in routers and switches where fast packet processing and temporary data storage require predictable access times and parallel bandwidth.
• Industrial Control Systems - PLCs and HMI devices benefit from the reliable volatile memory for runtime variables and display buffers, with the commercial temperature range supporting typical factory floor conditions.
• Embedded Computing - System-on-module designs and embedded processors use this SDRAM for program execution space and data caching where parallel interfacing reduces controller complexity.
• Legacy System Upgrades - The standard SDRAM architecture and pinout make this device suitable for replacing or extending memory in established designs requiring continued parts availability.

Unique Advantages

• Straightforward Integration: Standard SDRAM protocol and parallel interface eliminate the need for complex memory controllers or protocol translation.
• Proven Technology: Mature SDRAM architecture offers well-understood behavior and extensive reference designs, reducing development risk.
• Compact Package: The 8x8mm VFBGA footprint provides higher density than TSOP packages while maintaining routing accessibility.
• Single Supply Operation: 3.3V-only power requirement simplifies power distribution and reduces BOM count compared to multi-rail memory devices.
• Alliance Memory Availability: Sourcing from Alliance Memory provides access to legacy-compatible devices with focus on long-term supply continuity.

Why Choose MT48LC16M16A2F4-6A:GTR?

This SDRAM is positioned for designs requiring parallel memory with established SDRAM protocols. Engineers working on industrial controls, networking equipment, or embedded systems will find the 16M x 16 organization and 167 MHz speed grade well-suited to applications where volatile working memory must interface directly with processors or FPGAs. The commercial temperature rating and compact VFBGA package support typical embedded deployment scenarios.

While this product carries an obsolete lifecycle status, it remains relevant for legacy system support, repair inventories, and designs requiring form-fit-function compatibility with existing memory selections. Alliance Memory's focus on memory component availability makes this device a practical choice for sustaining engineering projects.
