Description and Introduction

256Mbit GDDR SDRAM The part **K4D553238F-JC33** is a memory IC manufactured by **Samsung**. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Samsung  
- **Part Number:** K4D553238F-JC33  
- **Type:** DDR SDRAM (Double Data Rate Synchronous Dynamic Random-Access Memory)  
- **Density:** 256Mb (32M x 8)  
- **Organization:** 32M words × 8 bits  
- **Voltage:** 2.5V (±0.2V)  
- **Speed Grade:** JC33 (333MHz @ CL=2.5)  
- **Package:** 66-pin TSOP-II (Thin Small Outline Package)  
- **Refresh:** 4K refresh cycles/64ms  
- **Operating Temperature:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) depending on variant  

### **Descriptions and Features:**
- **Double Data Rate (DDR):** Supports data transfer on both rising and falling clock edges.  
- **Burst Length:** Programmable burst lengths (2, 4, 8).  
- **CAS Latency:** Supports CL=2.5 at 333MHz.  
- **Auto Precharge:** Supports auto precharge for efficient memory management.  
- **On-Die Termination (ODT):** Reduces signal reflection for improved signal integrity.  
- **Low Power Consumption:** Operates at 2.5V, optimizing power efficiency.  
- **SSTL_2 Interface:** Uses Stub Series Terminated Logic for 2.5V (SSTL_2) signaling.  
- **Applications:** Commonly used in networking equipment, embedded systems, and consumer electronics requiring DDR1 memory.  

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

Application Scenarios & Design Considerations

256Mbit GDDR SDRAM

Alternative Part Number

  • MT47H128M16RT-25E --: DDR2 SDRAM in the same density class with comparable speed grade; widely available and pin-compatible at the board level for many designs.
  • IS43DR16160B-3DBL --: DDR2 SDRAM alternative from a different vendor with similar organization and speed, suitable as a drop-in replacement in many applications.
  • W972GG6JB-25 --: DDR2 SDRAM offering comparable capacity and performance, providing a second-source option when Samsung parts are unavailable.
  • MT47H32M16HR-25E --: DDR2 SDRAM with comparable density and organization, widely available and pin-compatible in many designs.
  • IS43DR16320B-25DBL --: DDR2 SDRAM with matching density and 333 MHz speed class, good alternative when SEC parts are unavailable.
  • W972GG6KB-25 --: DDR2 SDRAM offering comparable capacity and speed grade; a viable secondary source for cost or supply reasons.
