Description and Introduction

128Mbit Synchronous DRAMs The HYB39S128800CT-7 is a 128Mbit (16M x 8) Synchronous DRAM (SDRAM) manufactured by Infineon Technologies (formerly Siemens).  

### **Key Specifications:**  
- **Organization:** 16M words × 8 bits  
- **Density:** 128Mbit  
- **Voltage Supply:** 3.3V ± 0.3V  
- **Speed Grade:** 7ns (143MHz)  
- **Package:** 54-pin TSOP-II  
- **Refresh Cycles:** 4096 refresh cycles every 64ms  
- **Burst Lengths:** 1, 2, 4, 8, or full page  
- **CAS Latency (CL):** 2 or 3 (programmable)  
- **Operating Temperature:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  

### **Features:**  
- Fully synchronous operation with a single 3.3V power supply  
- Internal pipelined architecture for high-speed data transfer  
- Auto Refresh (CBR) and Self Refresh modes  
- Programmable burst read and write operations  
- Compatible with JEDEC-standard SDRAM specifications  
- Four internal banks for concurrent operation  

This SDRAM is commonly used in networking, telecommunications, and computing applications requiring high-speed memory access.

Application Scenarios & Design Considerations

128Mbit Synchronous DRAMs

Alternative Part Number

  • MT48LC8M16A2P-7E --: 128Mb SDR SDRAM organized as 8M x 16, 7ns speed grade, functionally equivalent to the original 128Mb SDRAM device.
  • IS42S16800E-7TL --: 128Mb SDR SDRAM in 8M x 16 organization with 7ns access time, a common drop-in replacement for HYB39S128800 series.
  • W9864G6JH-7 --: 64Mb SDR SDRAM with 7ns speed grade; lower density but pin-compatible in many designs and widely available as an alternative SDR SDRAM option.
