Description and Introduction

32Mx8, 16Mx16 256Mb DDR Synchronous DRAM The IS43R16160B-5TLI is a 256Mb (16Mx16) DDR SDRAM manufactured by ISSI (Integrated Silicon Solution Inc.).  

### **Specifications:**  
- **Density:** 256Mb (16M words × 16 bits)  
- **Organization:** 16M × 16  
- **Voltage:** 1.8V ± 0.1V  
- **Speed Grade:** -5 (200MHz, CL=3)  
- **Refresh:** 8K refresh cycles every 64ms  
- **Burst Length:** 2, 4, or 8  
- **CAS Latency (CL):** 2, 2.5, 3  
- **Package:** 60-ball FBGA (8mm × 10.5mm)  
- **Operating Temperature:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  

### **Descriptions & Features:**  
- **Double Data Rate (DDR) Interface:** Transfers data on both rising and falling clock edges.  
- **Programmable Burst Length:** Supports 2, 4, or 8.  
- **Auto Refresh & Self Refresh Modes:** For power efficiency.  
- **Differential Clock Inputs (CK & /CK):** Improves noise immunity.  
- **Data Strobe (DQS):** Edge-aligned for write operations, center-aligned for reads.  
- **On-Die Termination (ODT):** Reduces signal reflections.  
- **4 Internal Banks:** Allows concurrent operations.  
- **RoHS Compliant:** Lead-free and halogen-free.  

This DDR SDRAM is commonly used in networking, industrial, and consumer electronics applications.

Application Scenarios & Design Considerations

32Mx8, 16Mx16 256Mb DDR Synchronous DRAM

Alternative Part Number

  • MT46V16M16P-5B:M --: Same 256Mb DDR SDRAM density, 16M x16 organization, 66-pin TSOP package, and 5ns speed grade; widely available drop-in equivalent from a major DRAM vendor.
  • W9825G6KH-5 --: 256Mb DDR SDRAM organized as 16M x16 with 5ns speed grade in TSOP-66 package; pin-compatible and commonly used as a second source for ISSI DDR parts.
  • AS4C16M16D1-5TCN --: Alliance Memory specializes in legacy DRAM second sources; this 256Mb 16M x16 DDR SDRAM at 5ns in TSOP-66 is a direct functional replacement for the IS43R16160B.
