64M(4Mx16) DDR SDRAM The HY5DV641622AT-33 is a DDR SDRAM module manufactured by Hynix (now SK Hynix). Here are its key specifications:

- **Type**: DDR SDRAM (Double Data Rate Synchronous Dynamic Random-Access Memory)  
- **Density**: 64Mbit x 16 (1Gbit total)  
- **Organization**: 4 Banks x 4M x 16  
- **Speed**: -33 (300MHz, DDR-600, PC4800)  
- **Voltage**: 2.5V ±0.2V  
- **Package**: 66-pin TSOP-II  
- **Data Rate**: 600Mbps/pin  
- **CAS Latency (CL)**: 3  
- **Burst Length**: 2, 4, 8  
- **Refresh**: 8K/64ms (Self-Refresh & Auto-Refresh)  
- **Operating Temperature**: Commercial (0°C to 70°C)  

This module is commonly used in memory applications requiring high-speed data transfer.

Application Scenarios & Design Considerations

64M(4Mx16) DDR SDRAM

Alternative Part Number

  • MT48LC4M16A2P-7E --: 64Mb SDRAM organized as 4M x 16, same 54-pin TSOP package and 3.3V interface; 7ns speed grade meets or exceeds the -33 (3.3ns/133MHz-class) timing, making it a strong drop-in alternative.
  • IS42S16400J-7TL --: 64Mb SDRAM in 4M x 16 organization with 3.3V supply and 54-pin TSOP II footprint; widely available and commonly used as a replacement for HY5DV-series 64Mb SDRAM parts.
  • W9864G6JH-6 --: 64Mb SDRAM (4M x 16) in 54-pin TSOP II with 3.3V operation; 6ns speed grade covers the original timing requirement and it is a cost-effective second-source option.
