Description and Introduction

256-MBIT SYNCHRONOUS DRAM The IC42S16160B-7TL is a synchronous DRAM (SDRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Part Number:** IC42S16160B-7TL  
- **Manufacturer:** ISSI (Integrated Silicon Solution, Inc.)  
- **Type:** Synchronous DRAM (SDRAM)  
- **Density:** 256Mbit (16M x 16)  
- **Organization:** 4 Banks x 4M x 16  
- **Voltage Supply:** 3.3V ± 0.3V  
- **Speed Grade:** -7 (143MHz clock frequency)  
- **Access Time:** 7ns (tAC)  
- **CAS Latency:** 2, 3 (programmable)  
- **Refresh Cycles:** 4096 refresh cycles / 64ms  
- **Package:** 54-pin TSOP-II (400mil width)  
- **Operating Temperature:** Commercial (0°C to +70°C)  

### **Descriptions:**
- The IC42S16160B-7TL is a high-speed CMOS synchronous DRAM designed for applications requiring high bandwidth and low power consumption.  
- It supports burst read and write operations with programmable burst lengths (1, 2, 4, 8, or full page).  
- The device is compatible with JEDEC-standard SDRAMs and operates with a single 3.3V power supply.  

### **Features:**
- **Synchronous Operation:** Clock-controlled commands and data transfers.  
- **Programmable Burst Length:** Supports 1, 2, 4, 8, or full-page bursts.  
- **Auto Refresh & Self Refresh:** Supports power-saving modes.  
- **CAS Latency Options:** 2 or 3 cycles (selectable via mode register).  
- **Burst Termination:** Controlled by burst stop or precharge commands.  
- **Low Power Consumption:** Standby and auto refresh modes reduce power usage.  
- **Single 3.3V Power Supply:** Compatible with standard SDRAM interfaces.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

256-MBIT SYNCHRONOUS DRAM

Alternative Part Number

  • MT48LC4M16A2P-7E --: Same 64Mb SDR SDRAM density in 4M x 16 organization with 7ns speed grade, widely available and pin-compatible in the same TSOP-II package.
  • W9864G6JH-7 --: 64Mb SDR SDRAM organized as 4M x 16 with 7ns access time, a common drop-in alternative for ISSI SDR SDRAM parts.
  • AS4C4M16SA-7TCN --: 4M x 16 64Mb SDR SDRAM with 7ns speed grade in TSOP-II, specifically marketed as a replacement for legacy ISSI SDR SDRAM devices.
