Description and Introduction

4M x 32 128Mb SYNCHRONOUS DRAM The **IS42S32400E-6TL** is a **32Mbit (4M x 8) Synchronous DRAM (SDRAM)** manufactured by **ISSI (Integrated Silicon Solution, Inc.)**.  

### **Key Specifications:**  
- **Density:** 32Mbit (4M words × 8 bits)  
- **Organization:** 4 banks × 1,048,576 rows × 8 columns  
- **Voltage Supply:** 3.3V (±0.3V)  
- **Speed Grade:** -6 (166 MHz clock frequency)  
- **Access Time:** 5.4 ns (CL=3)  
- **CAS Latency (CL):** 2, 3 programmable  
- **Burst Length:** 1, 2, 4, 8, full page  
- **Refresh:** 4,096 refresh cycles every 64ms  
- **Interface:** LVTTL  
- **Package:** 54-pin TSOP II  

### **Features:**  
- Fully synchronous operation with a single 3.3V power supply  
- Programmable burst lengths (1, 2, 4, 8, full page)  
- Auto Refresh (CBR) and Self Refresh modes  
- Internal pipelined operation for high-speed data transfer  
- Auto Precharge option for burst read/write operations

This SDRAM is commonly used in applications requiring high-speed memory, such as networking equipment, embedded systems, and consumer electronics.

Application Scenarios & Design Considerations

4M x 32 128Mb SYNCHRONOUS DRAM

Alternative Part Number

  • MT48LC4M32B2P-6A --: Same 128Mb SDR SDRAM organization (4M x 32) with 166MHz speed grade, widely available and pin-compatible in the same TSOP package.
  • W9825G6KH-6 --: 128Mb SDR SDRAM in 4M x 32 configuration with 166MHz speed, a common drop-in alternative for ISSI SDRAM parts.
  • AS4C4M32S-6TCN --: Directly comparable 128Mb SDR SDRAM organized as 4M x 32 at 166MHz, offered as a legacy SDRAM replacement for ISSI devices.
