Description and Introduction

128Mb DDR SDRAM The **K4H281638D-TCA2** is a memory chip manufactured by **Samsung**. Below are the factual specifications, descriptions, and features based on available knowledge:  

### **Specifications:**  
- **Manufacturer:** Samsung  
- **Part Number:** K4H281638D-TCA2  
- **Memory Type:** DDR SDRAM (Double Data Rate Synchronous Dynamic Random-Access Memory)  
- **Density:** 256Mb (Megabit)  
- **Organization:** 16M x 16 (16 million words × 16 bits)  
- **Voltage:** 2.5V ± 0.2V  
- **Speed:** TC-A2 (typically indicates a speed grade, but exact frequency depends on datasheet)  
- **Package:** TSOP (Thin Small Outline Package)  
- **Pins:** 66-pin configuration  

### **Descriptions & Features:**  
- Designed for high-speed data transfer applications.  
- Supports **Double Data Rate (DDR)** operation, allowing data transfer on both rising and falling clock edges.  
- **Low power consumption** with 2.5V operating voltage.  
- **Synchronous operation** with a system clock for precise timing.  
- **Auto refresh and self-refresh** modes for power efficiency.  
- **CAS Latency (CL) support** for optimized performance.  
- Commonly used in **consumer electronics, networking devices, and embedded systems**.  

For exact timing parameters (e.g., clock frequency, latency), refer to Samsung's official datasheet for **K4H281638D-TCA2**.

Application Scenarios & Design Considerations

128Mb DDR SDRAM

Alternative Part Number

  • MT46V16M8P-6T --: 16M x 8 DDR SDRAM in TSOP package with comparable speed grade, a common drop-in alternative from a different series.
  • HY5DU121622DTP-D43 --: 128Mb DDR SDRAM organized 16M x 8, similar density and interface, widely used as a substitute.
  • IS43R16800E-6TL --: 128Mb DDR SDRAM 16M x 8 in TSOP, pin-compatible class device suitable for replacement.
  • MT48LC16M16A2P-75 --: 256Mb SDR SDRAM in 16M x16 organization, same 54-pin TSOP package and 3.3V interface, widely available and a common drop-in replacement for K4H281638D.
  • IS42S16160D-7TL --: 256Mb SDR SDRAM organized as 16M x16 with compatible 3.3V signaling and TSOP-II footprint, pin-compatible with the Samsung part and well stocked.
  • W9825G6JH-6 --: 256Mb SDR SDRAM 16M x16 device with matching 54-pin TSOP package and 3.3V operation, a cost-effective alternative with similar timing grades.
