MPN： H5AN8G6NAFR ✓ 啟用中H5AN8G6NAFR 概覽
DDR4 SDRAM is the fourth generation of double data rate synchronous dynamic random-access memory, succeeding DDR3. It provides higher module density and lower voltage (1.2V vs 1.5V) while delivering increased bandwidth. DDR4 is a key component in modern computing systems, from servers and desktops to embedded and networking equipment, where it serves as the main system memory. The H5AN8G6NAFR is part of the DDR4 SDRAM family, which includes x4, x8, and x16 configurations, and is essential for high-performance computing.
Key features include a 1.2V power supply, 8Gb density, 512M x 16 organization, and a 96-ball FBGA package. It supports data rates up to 2400 MT/s (PC4-19200) and includes features such as auto self-refresh, auto precharge, asynchronous reset, data mask, dynamic on-chip termination (ODT), ZQ calibration, CRC, and write leveling. The device is lead-free and halogen-free, RoHS compliant, and operates over a temperature range of 0°C to +85°C.
Technically, the H5AN8G6NAFR uses a high-performance CMOS process and features a pseudo-open-drain interface for compatibility with DDR4 controllers. It incorporates a DLL (Delay-Locked Loop) to align data output with the clock, and supports on-die termination for improved signal integrity. The device also includes a temperature sensor for auto-refresh rate adjustment, enhancing reliability in varying thermal conditions.
Typical applications include servers, data centers, networking equipment, and high-end consumer electronics such as gaming PCs and workstations. Its high density and bandwidth make it ideal for memory-intensive tasks like virtualization, big data analytics, and real-time signal processing. The 1.2V operation reduces power consumption, making it suitable for energy-efficient designs.
When designing with this device, ensure proper decoupling of the VDD and VDDQ supplies with 0.1uF and 1uF capacitors placed close to the pins. Follow the DDR4 layout guidelines for impedance matching and signal integrity, and use the ZQ calibration resistor (240 ohm) as specified in the datasheet.

主要差異化特點
- High density 8Gb in x16 organization (對比MT40A512M16JY-075E)
- Low 1.2V supply voltage (對比K4A8G165WB-BCWE)
- Wide operating temperature range (對比AS4C512M16D4A-62BCN)
設計說明
Ensure stable power supply to VDD and VDDQ pins. Use 0.1uF and 1uF decoupling capacitors placed as close as possible to each power pin. The 1.2V supply should be clean and well-regulated to avoid data corruption.
Follow DDR4 layout guidelines for impedance matching and signal integrity. Route DQ, DQS, and address/control lines with controlled impedance (typically 40-50 ohms). Keep trace lengths matched within the specified skew limits to ensure reliable operation at 2400 MT/s.
The H5AN8G6NAFR operates up to +85°C. Ensure adequate airflow or heatsinking in high-density designs. Monitor the temperature sensor and adjust refresh rate if necessary to maintain data integrity.
