Overview
The MT47H64M16NF-25E: M is a 1Gb DDR2 SDRAM device designed for stable, high-reliability memory applications. It features a 64M × 16 organization and operates at 1.8 V, complying fully with JEDEC DDR2 standards. This component is widely used in embedded and industrial systems that require predictable timing behavior and long-term availability rather than frequent platform upgrades.
With an internal 8-bank architecture and 4n-prefetch design, the MT47H64M16NF-25E:M supports efficient data throughput while maintaining controlled power consumption.

Features
- DDR2-800 support with 2.5 ns tCK
- Differential DQS/DQS# signaling for improved timing margins
- On-Die Termination (ODT) to enhance signal integrity
- Internal DLL for clock alignment
- Programmable CAS latency and additive latency
- Fully JEDEC-compliant DDR2 interface
- Pb-free, RoHS-compliant package
These features allow stable operation in multi-bank access scenarios and reduce design complexity for memory controllers.
Typical Application Scenarios
- Embedded computing platforms
- Industrial automation systems
- Networking and communication equipment
- Legacy systems requiring DDR2 memory support
- Long-lifecycle products where component continuity matters
The MT47H64M16NF-25E:M is especially suitable for systems where DDR2 remains a validated and supported memory standard.
Performance Comparison
Compared with lower-speed DDR2 variants (DDR2-533 / DDR2-667), the MT47H64M16NF-25E:M offers:
- Higher bandwidth at DDR2-800
- Improved timing stability due to tighter clock cycle specification
- Better signal integrity via ODT and differential strobes
While newer DDR3/DDR4 memories provide higher densities, DDR2 solutions like this device remain advantageous for cost-controlled and legacy designs with proven controller compatibility.
Conclusion
The MT47H64M16NF-25E:M delivers a balanced combination of performance, reliability, and electrical stability. Its DDR2-800 capability, x16 data width, and industrial temperature support make it a dependable choice for embedded and industrial systems that prioritize consistency and long-term supply over bleeding-edge specifications.
