The MT47H64M8JN-3 IT:F is a DDR2 SDRAM (Double Data Rate 2 Synchronous Dynamic Random-Access Memory) component produced by Micron Technology Inc. It's designed to deliver high-speed data access for a variety of applications requiring significant memory bandwidth. This particular variant, denoted with "IT," likely indicates an industrial temperature grade.

Applications

• Industrial PCs
• Embedded systems operating in harsh environments
• Networking equipment
• Automotive systems
• Medical devices
• Applications requiring extended temperature range operation

Features

• 64Mb x 8 organization
• DDR2 architecture: Provides high bandwidth
• Double data rate: Transfers data on both rising and falling edges of the clock signal
• On-chip DLL (Delay-Locked Loop): Ensures accurate timing
• Data mask (DM): Allows selective write operations
• Burst lengths: Supports burst lengths of 2, 4, and 8
• Auto precharge: Simplifies memory management
• Differential clock inputs (CK, /CK): Improves noise immunity
• Industrial Temperature Grade: Specifically designed to operate in a wider temperature range compared to commercial grade memory

Benefits

• Reliable operation in harsh environments (extended temperature range)
• Increased system performance due to faster memory access
• Higher bandwidth for demanding applications
• Improved responsiveness in memory-intensive tasks
• Enhanced stability

Additional Details

The MT47H64M8JN-3 IT:F typically operates at a clock frequency of up to 333 MHz, resulting in a data transfer rate of up to 667 Mbps (PC2-5300). It requires a power supply voltage of 1.8V. The device is commonly available in a FBGA (Fine-pitch Ball Grid Array) package. The "IT" designation suggests that this memory component is suitable for applications with stringent environmental requirements, such as industrial and automotive applications where reliability across a broad temperature range is crucial.
