Description and Introduction

4M x 16Bit x 4 Banks (256-MBIT) SDRAM The IC42S16160-6TG is a 16Mbit (1M x 16) Synchronous DRAM (SDRAM) manufactured by Silicon Integrated Systems (SiS). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Density:** 16Mbit (1M words × 16 bits)  
- **Organization:** 1 Meg × 16  
- **Voltage Supply:** 3.3V ± 0.3V  
- **Speed Grade:** -6 (6ns access time, 166MHz operating frequency)  
- **Package:** 54-pin TSOP-II  
- **Refresh Cycles:** 4096 refresh cycles every 64ms  
- **Burst Lengths:** 1, 2, 4, 8, or full page  
- **CAS Latency (CL):** 2 or 3 (programmable)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**
- **Type:** Synchronous DRAM (SDRAM)  
- **Interface:** Fully synchronous with a single 3.3V power supply  
- **Architecture:** Four internal banks for concurrent operations  
- **Data I/O:** Double Data Rate (DDR) not supported (standard SDRAM)  

### **Features:**
- **High-Speed Operation:** Up to 166MHz clock frequency  
- **Programmable Burst Length:** Supports 1, 2, 4, 8, or full-page burst modes  
- **Auto Refresh & Self Refresh:** Supports both modes for power efficiency  
- **Single 3.3V Power Supply:** Low power consumption  
- **Pipelined Operation:** Enables high-speed data transfer  
- **On-Chip PLL:** Eliminates clock skew  
- **Compatible with JEDEC Standards:** Meets industry-standard SDRAM specifications  

This SDRAM is commonly used in memory modules for PCs, networking devices, and embedded systems requiring moderate-speed memory access.

Application Scenarios & Design Considerations

4M x 16Bit x 4 Banks (256-MBIT) SDRAM

Alternative Part Number

  • MT48LC4M16A2P-6A --: Same 64Mb SDR SDRAM density in a 4M x 16 organization with 166MHz speed grade, widely available and pin-compatible in the TSOP-II package.
  • IS42S16160D-6TL --: Direct 16M x 16 SDR SDRAM equivalent from ISSI with matching 166MHz timing and TSOP-II footprint, commonly used as a drop-in replacement.
  • W9864G6GH-6 --: 64Mb SDR SDRAM organized as 4M x 16 with 166MHz speed grade, offering comparable timing and package compatibility for this application.
  • MT48LC16M16A2P-6A --: Micron 16M x16 SDR SDRAM with 166MHz speed grade, functionally equivalent and commonly used as an alternative to the ISSI part.
  • W9825G6KH-6 --: Winbond 16M x16 SDR SDRAM rated at 166MHz, pin-compatible with the original and a cost-effective second source.
