The **H5TC4G83AFR-RDA** is a high-density, high-performance synchronous dynamic random-access memory (SDRAM) chip manufactured by **SK hynix**. It is commonly found in laptop RAM modules (SODIMMs), embedded systems, and consumer electronics. --- ## 1. Technical Specifications The following table highlights the core technical parameters of the chip: | Feature | Specification | | :--- | :--- | | **Manufacturer** | SK hynix | | **Part Number** | H5TC4G83AFR-RDA | | **Memory Type** | DDR3L SDRAM (Low Voltage) | | **Density** | 4 Gigabits (512 Megabytes) | | **Organization** | 512M x 8 bits | | **Clock Speed** | 800 MHz (Effective 1600 Mbps - DDR3-1600) | | **Voltage (VDD/VDDQ)** | 1.35V (Backward compatible with 1.5V) | | **Package Type** | 78-ball FBGA | | **Operating Temp** | 0°C to 95°C (Commercial Grade) | --- ## 2. Key Features - **Low Voltage (DDR3L):** Operating at 1.35V reduces power consumption by significantly compared to standard 1.5V DDR3, making it ideal for mobile devices and energy-efficient servers. - **Bi-directional Differential Data Strobe:** Optimizes data transfer timing. - **8n-bit Prefetch Architecture:** Allows high-speed data transfer rates. - **Internal Bank Structure:** Organized into 8 internal banks for concurrent operation. - **On-Die Termination (ODT):** Improves signal integrity by terminating the signal within the chip itself, reducing reflections. --- ## 3. Part Number Decoder To understand the specific variant, we can break down the suffix **"RDA"**: * **R:** Denotes the "Rie" revision (C-die or specific generation). * **DA:** Refers to the speed bin and latency. * **1600 (DDR3-1600)** * **CAS Latency:** 11-11-11 --- ## 4. Application Use Cases 1. **Computing:** Used as the memory chips on DDR3L SODIMM or UDIMM sticks for laptops and desktops. 2. **Embedded Systems:** High-definition televisions, set-top boxes, and automotive infotainment systems. 3. **Networking:** Routers and switches requiring high-speed data buffering. ---
