Description and Introduction

256Mb DDR2 SDRAM The part **HY5PS561621BFP-Y5** is a DDR2 SDRAM manufactured by **Hynix**. Here are its specifications based on Ic-phoenix technical data files:  

- **Type**: DDR2 SDRAM  
- **Density**: 512Mb (64M x 8)  
- **Organization**: 64M words × 8 bits  
- **Speed**: **-Y5** speed grade (PC2-5300, 667 MHz)  
- **Voltage**: 1.8V ± 0.1V  
- **Package**: FBGA (Fine-pitch Ball Grid Array)  
- **Operating Temperature**: Commercial (0°C to 85°C)  
- **Refresh**: 8K refresh cycles (64ms)  
- **Burst Length**: 4 or 8 (programmable)  
- **CAS Latency**: 3, 4, 5 (programmable)  
- **Data Rate**: 667 Mbps/pin (DDR2-667)  

This part is compliant with **JEDEC DDR2 standards** and is typically used in computing and embedded applications.  

(Note: If more detailed specifications are needed, refer to the official **Hynix datasheet** for HY5PS561621BFP-Y5.)

Application Scenarios & Design Considerations

256Mb DDR2 SDRAM

Alternative Part Number

  • MT47H64M16HR-3IT:H --: 1Gb DDR2 SDRAM in 16M x 16 organization, same density and interface as the original, widely available and pin-compatible in most designs.
  • K4T51163QJ-BCE7 --: 512Mb DDR2 SDRAM with comparable speed grade and organization, a common drop-in alternative from a major DRAM vendor.
  • W9751G6KB-25 --: 512Mb DDR2 SDRAM offering similar density, voltage, and timing, suitable as a second-source replacement when the original is unavailable.
  • MT47H64M16HR-25E --: 1Gb DDR2 SDRAM in 84-ball FBGA with comparable organization and speed grade, widely available and pin-compatible in most designs.
