Description and Introduction

64M(4Mx16) DDR SDRAM The part **HY5DV641622AT-5** is a **512Mb (32Mx16) DDR SDRAM** manufactured by **Hynix**. Below are its key specifications:

- **Density**: 512Mb (32M words × 16 bits)  
- **Organization**: 4 banks × 8M words × 16 bits  
- **Voltage**: 2.5V ± 0.2V (core and I/O)  
- **Speed**: **-5** (5ns cycle time, 200MHz clock rate)  
- **Package**: 66-pin TSOP-II (400mil width)  
- **Refresh**: 8K refresh cycles / 64ms (self-refresh supported)  
- **Burst Length**: 2, 4, or 8 (programmable)  
- **CAS Latency (CL)**: 2, 2.5, or 3 (programmable)  
- **Operating Temperature**: Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  

This DDR SDRAM is commonly used in networking, computing, and embedded systems requiring high-speed memory.

Application Scenarios & Design Considerations

64M(4Mx16) DDR SDRAM

Alternative Part Number

  • MT48LC4M16A2P-6A --: 64Mb SDRAM organized as 4M x 16, same 54-pin TSOP package and PC133-class speed grade, widely available and a common drop-in replacement for Hynix 64Mb SDRAM.
  • IS42S16400J-7TL --: 64Mb SDRAM in 4M x 16 organization with compatible 54-pin TSOP-II pinout and 3.3V interface, a well-stocked alternative with similar timing.
  • W9864G6JH-6 --: 64Mb SDRAM 4M x 16 device with matching package and voltage, offering comparable performance as a second-source option for the Hynix part.
  • IS42S16400F-6TL --: 64Mb SDRAM in 4M x 16 configuration with compatible pinout and 3.3V supply; widely available drop-in style replacement for HY5DV641622AT.
