MPN: AS4C512M16D4A-62BCNTR ✓ Hoạt độngAS4C512M16D4A-62BCNTR Tóm tắt
DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random-Access Memory) is a type of volatile memory that transfers data on both edges of the clock signal, doubling the data rate compared to DDR3. It operates at a lower voltage (1.2V) than DDR3 (1.5V), reducing power consumption. DDR4 is the industry standard for modern computing, offering higher density and speed while maintaining backward compatibility with JEDEC standards.
Key features include a 1.2V power supply, 1600MHz clock rate (PC4-3200), 18ns CAS latency, and a 96-ball FBGA package. The device supports on-die termination (ODT), programmable read/write latencies, and auto-refresh and self-refresh modes. It is available in commercial temperature range (0°C to +95°C) and is RoHS compliant.
The AS4C512M16D4A-62BCNTR uses a 20nm-class process technology, offering high density and low power. It features a 16n prefetch architecture, which improves bandwidth efficiency. The device includes a temperature sensor for thermal management and supports DLL (Delay-Locked Loop) for precise timing.
Typical applications include servers, networking equipment, industrial PCs, and embedded systems requiring high-capacity, high-speed memory. Its 512M x 16 organization is ideal for systems with a 16-bit data bus, such as high-end routers and switches.
When designing with this device, ensure proper decoupling capacitors near the power pins and follow the layout guidelines in the datasheet to minimize signal integrity issues. The device requires a 1.2V supply and a separate VPP (2.5V) for wordline boost, which must be generated correctly.

Ghi chú thiết kế
The AS4C512M16D4A-62BCNTR requires a 1.2V VDD supply and a separate 2.5V VPP supply for wordline boost. Ensure these supplies are clean and well-regulated. Use 0.1uF decoupling capacitors close to each VDD and VDDQ pin, and a 10uF bulk capacitor near the power entry point. The VPP supply should be capable of sourcing transient current during write operations.
For high-speed DDR4 signals, maintain controlled impedance of 40-50 ohms for DQ, DQS, and address/command lines. Keep trace lengths matched within +/- 10 mils for data groups. Use ground planes beneath the FBGA package to minimize noise. Follow the layout guidelines in the Alliance Memory datasheet for optimal signal integrity.
The AS4C512M16D4A-62BCNTR has a maximum operating temperature of +95°C. In high-ambient environments, ensure adequate airflow or heatsinking. The 96-ball FBGA package has a thermal resistance of approximately 20°C/W (theta_JA) with proper PCB copper. Monitor junction temperature to avoid exceeding the absolute maximum rating of +95°C.
