Description and Introduction

1M x 16 (16-MBIT) DYNAMIC RAM WITH FAST PAGE MODE The IS41LV16105-50TI is a high-speed CMOS synchronous dynamic RAM (SDRAM) manufactured by Integrated Silicon Solution Inc. (ISSI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 1M x 16-bit  
- **Density:** 16 Megabit (2M x 8 or 1M x 16)  
- **Voltage Supply:** 3.3V ± 0.3V  
- **Access Time:** 5.4ns (CL=3)  
- **Operating Frequency:** 143MHz (for -50 speed grade)  
- **Refresh Cycles:** 4096 refresh cycles every 64ms  
- **CAS Latency (CL):** 2 or 3 programmable  
- **Burst Length:** 1, 2, 4, 8, or full page  
- **Package:** 50-pin TSOP II (400 mil width)  
- **Operating Temperature:** Industrial (-40°C to +85°C)  

### **Descriptions:**
- Fully synchronous operation with a single 3.3V power supply  
- Internal pipelined operation for high-speed data transfer  
- Auto Refresh (CBR) and Self Refresh modes  
- Programmable burst read and write operations  
- Supports sequential and interleaved burst modes  

### **Features:**
- **High Performance:** 143MHz operation with low latency  
- **Low Power Consumption:** Standby and power-down modes for reduced power usage  
- **Auto Precharge:** Supports auto precharge for efficient memory management  
- **Burst Mode:** Configurable burst lengths for flexible data access  
- **Industrial Temperature Range:** Suitable for harsh environments  

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

Application Scenarios & Design Considerations

1M x 16 (16-MBIT) DYNAMIC RAM WITH FAST PAGE MODE

Alternative Part Number

  • AS4C1M16S-5TCN --: Alliance Memory specializes in drop-in replacements for legacy ISSI SRAM/DRAM; this 1M x 16 asynchronous SRAM matches the 50ns speed grade and TSOP package, making it the closest functional substitute.
  • CY7C1041CV33-10ZXI --: Cypress 1M x 16 asynchronous SRAM with similar organization and TSOP II package; a widely available alternative with comparable timing characteristics for legacy designs.
  • IS61LV10248-55TLI --: Same manufacturer's 1M x 8 low-voltage SRAM family with similar 50-55ns access time; useful when board layout allows byte-wide configuration and keeps vendor consistency.
