Description and Introduction

1M x 16 (16-MBIT) DYNAMIC RAM WITH FAST PAGE MODE The IS41C16105-50K is a 16Mbit (1M x 16) CMOS DRAM manufactured by ISSI (Integrated Silicon Solution Inc.). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 1M x 16  
- **Density:** 16Mbit  
- **Access Time:** 50 ns  
- **Operating Voltage:** 5V ±10%  
- **Package:** 42-pin SOP (Small Outline Package)  
- **Refresh Cycles:** 1K cycles every 8ms (CAS-before-RAS refresh)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**
- The IS41C16105-50K is a high-speed, low-power DRAM designed for applications requiring moderate memory capacity.  
- It supports both fast page mode and static column mode operations.  
- The device is compatible with industry-standard 16-bit memory interfaces.  

### **Features:**
- **Fast Page Mode Operation:** Enhances access speed for sequential reads.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **Single 5V Power Supply:** Simplifies system design.  
- **CAS-before-RAS Refresh:** Reduces external refresh circuitry complexity.  
- **TTL-Compatible Inputs and Outputs:** Ensures compatibility with standard logic levels.  
- **Industry-Standard Pinout:** Facilitates easy replacement in existing designs.  

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

Application Scenarios & Design Considerations

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

Alternative Part Number

  • AS4C1M16S-5TCN --: 1M x 16 asynchronous DRAM in the same 50 ns speed grade and TSOP package, a direct drop-in replacement for the IS41C16105.
  • MT4C1M16C3DJ-5 --: 1M x 16 fast page mode DRAM with 50 ns access time, functionally equivalent to the IS41C16105-50K.
  • HM5116105F-5 --: 1M x 16 DRAM in 50 ns grade with compatible pinout and timing, suitable as a second-source alternative.
  • AS4C1M16S-50TCN --: Alliance Memory specializes in legacy DRAM drop-in replacements; this 1M x 16 asynchronous SRAM-class part matches the 50 ns speed grade and 5 V operation of the IS41C16105, making it a strong form-fit-function substitute.
  • CY7C1041CV33-10ZXC --: Cypress 1M x 16 asynchronous SRAM with similar organization and pinout; a widely available alternative when the 50 ns timing can be relaxed to 10 ns, with broad industrial availability.
  • IS61WV102416BLL-10TLI --: Same manufacturer's 1M x 16 high-speed asynchronous SRAM in a compatible package; staying within ISSI keeps electrical and packaging compatibility while offering a different series naming for easy distinction.
