The MT46V16M16P-75IT is a 256Mb DDR SDRAM component manufactured by Micron Technology. It's designed for high-speed memory applications requiring substantial bandwidth and low latency. This particular configuration features a 16Mb x 16 organization, indicating its memory density and data bus width. The -75 in the part number signifies a clock rate corresponding to a 75 MHz operation, yielding a data transfer rate up to 133 MHz.

Applications

• High-performance computing systems
• Graphics cards
• Networking equipment (routers, switches)
• Embedded systems with high memory requirements
• Digital signal processing (DSP) applications

Features

• Double data rate (DDR) architecture: Achieves high bandwidth by transferring data on both the rising and falling edges of the clock signal.
• Clock rate: Specified for 75 MHz operation.
• 16Mb x 16 organization: Offers a balance between memory density and data bus width.
• Differential clock inputs (CK and /CK): Enhances noise immunity and signal integrity.
• Data Mask (DM) for write operations: Allows selective writing to specific bytes within a word.
• Auto Refresh and Self Refresh modes: Minimizes power consumption during idle periods.
• Programmable Burst Length: Supports burst lengths of 2, 4, or 8 locations for optimized data transfer.
• Programmable CAS Latency (CL): Allows adjustment of read latency to match system requirements.

Benefits

• Increased system performance: DDR architecture provides significantly higher memory bandwidth compared to single data rate SDRAM.
• Reduced power consumption: Auto Refresh and Self Refresh modes help minimize power dissipation in low-activity states.
• Improved signal integrity: Differential clock inputs contribute to better noise immunity.
• Flexibility in system design: Programmable burst length and CAS latency enable optimization for different applications.
• High memory density: The 256Mb capacity allows for storing large amounts of data.

Additional Details

The MT46V16M16P-75IT operates at a voltage of typically 2.5V. It is packaged in a standard FBGA (Fine-Pitch Ball Grid Array) package for surface mount assembly. The operating temperature range is industrial, as indicated by the "IT" suffix, allowing operation in harsher environments. The component requires careful PCB layout to maintain signal integrity and minimize reflections, especially at higher clock speeds. Proper decoupling capacitors are essential for stable operation.
