The MT48LC16M16A2TG-7E IT:D is a 256Mb (16Meg x 16) SDRAM (Synchronous Dynamic Random-Access Memory) module manufactured by Micron Technology. It's designed for applications requiring high bandwidth and moderate density memory, such as graphics processing, networking, and embedded systems. It is a legacy part, so documentation can be sparse, but core SDRAM principles apply.

Applications:

• Graphics cards (older models).
• Networking equipment (routers, switches).
• Embedded systems (industrial controllers).
• Printers.
• Set-top boxes.

Features:

• 256Mb density (16Meg x 16 organization).
• PC133 SDRAM (133MHz clock speed).
• 3.3V power supply.
• CAS latency (CL) of 3.
• Double Data Rate (DDR) capability.
• LVTTL compatible inputs and outputs.
• Available in a TSOP package.

Benefits:

• Provides ample memory for various applications.
• Enables high-speed data transfer with PC133 SDRAM and DDR.
• Simplifies system design with a 3.3V power supply.
• Ensures compatibility with standard logic levels.

Additional Details:

The '-7E' likely refers to a specific speed grade (133MHz) and temperature range. The 'IT:D' likely specifies the industrial temperature range and packaging options. SDRAM needs to be constantly refreshed to retain data, which is handled automatically by the memory controller. The synchronous nature of SDRAM allows for higher data transfer rates compared to asynchronous DRAM. This specific module is a legacy part and may be difficult to source, but it highlights Micron's contribution to memory technology.
