Description and Introduction

256 Mb Single Data Rate Synchronous DRAM The **IS42S16160C-7TL** is a synchronous DRAM (SDRAM) manufactured by **Integrated Silicon Solution Inc. (ISSI)**. Below are its specifications, descriptions, and features:  

### **Specifications:**  
- **Memory 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)  
- **Refresh Mode:** Auto-Refresh & Self-Refresh  
- **Refresh Cycles:** 4096 cycles every 64ms  
- **Package:** 54-pin TSOP-II (400mil width)  
- **Operating Temperature:** Commercial (0°C to +70°C)  

### **Descriptions & Features:**  
- **Fully Synchronous Operation:** All signals are registered on the positive edge of the clock.  
- **Burst Mode Support:** Supports programmable burst lengths (1, 2, 4, 8, or full page).  
- **CAS Latency Options:** Supports CAS latencies of 2 or 3.  
- **Auto Precharge:** Configurable for each burst access.  
- **Low Power Consumption:** Standby and power-down modes reduce power usage.  
- **Single 3.3V Power Supply:** Compatible with standard 3.3V systems.  
- **Industrial Standard Pinout:** Matches JEDEC-compliant SDRAM pin configurations.  

This SDRAM is commonly used in networking, telecommunications, and embedded systems requiring high-speed, low-power memory.

Application Scenarios & Design Considerations

256 Mb Single Data Rate Synchronous DRAM

Alternative Part Number

  • MT48LC16M16A2P-7E --: 16M x 16 SDR SDRAM in TSOP-54 with 7ns speed grade, functionally equivalent to the IS42S16160C-7TL and widely available.
  • W9825G6KH-6 --: 16M x 16 SDR SDRAM, 54-pin TSOP II, compatible organization and interface; 6ns grade is faster and can replace the 7ns part.
  • AS4C16M16SA-7TCN --: Direct 16M x 16 SDR SDRAM alternative in TSOP-54 with 7ns speed, designed as a drop-in replacement for ISSI SDRAM parts.
