AS4C256M16D3L-12BCN 概要
DDR3L (Double Data Rate 3 Low Voltage) is a type of synchronous dynamic random-access memory (SDRAM) that operates at a reduced supply voltage of 1.35V, compared to standard DDR3's 1.5V. This lower voltage reduces power consumption by up to 20% while maintaining similar performance, making it ideal for power-sensitive applications such as laptops, embedded systems, and networking equipment. DDR3L is part of the DDR SDRAM family, which includes DDR, DDR2, DDR3, and DDR4, each offering increased speed and lower power.
Key features include a parallel interface with a 16-bit data bus, 800MHz clock speed, and a CAS latency of 20ns. The device supports JEDEC clock jitter specifications, ensuring reliable operation in high-speed systems. The 96-ball FBGA package provides excellent thermal and electrical performance, with a compact footprint suitable for space-constrained designs.
The AS4C256M16D3L-12BCN utilizes advanced CMOS technology to achieve high density and low power consumption. It supports various burst lengths and programmable CAS latency, allowing flexibility in system design. The device also includes on-die termination (ODT) and dynamic ODT for improved signal integrity, reducing the need for external termination resistors.
Typical applications include networking equipment (routers, switches), industrial automation, embedded computing, and consumer electronics such as set-top boxes and smart TVs. Its low voltage and high bandwidth make it suitable for DDR3L-based systems requiring 4Gbit density.
When designing with this memory, 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 1.35V supply and a separate VDDQ, which should be regulated accurately.

主な差別化要因
- Low voltage operation (1.35V) reduces power consumption by up to 20% compared to standard DDR3 （vs AS4C256M16D3-12BCN)
- Pin-compatible with multiple cross-brand DDR3L 4Gbit parts （vs MT41K256M16HA-125)
- RoHS compliant and halogen-free （vs K4B4G1646E-BYMA)
設計ノート
For high-speed DDR3L routing, maintain controlled impedance of 40-50 ohms for DQ/DQS signals and 50-60 ohms for address/command signals. Keep trace lengths matched within +/- 0.5mm for each byte lane. Use ground planes beneath the memory area to reduce noise. Refer to the Alliance Memory layout guidelines in the datasheet for specific recommendations.
Decouple VDD and VDDQ with 0.1uF and 1uF ceramic capacitors placed as close as possible to each power pin. Use a bulk capacitor of 10uF near the memory. Ensure the 1.35V supply has low ripple (<50mV) and adequate current capability. The VDDQ supply should be separate or well-filtered to avoid noise coupling.
The AS4C256M16D3L-12BCN has a maximum operating temperature of 95C (Tc). For high-density systems, ensure adequate airflow or a heatsink to keep the case temperature below this limit. The FBGA package has a thermal resistance of approximately 20C/W, so power dissipation of 2W would raise the case temperature by 40C above ambient.
