AS4C256M16D3LC-12BIN Overview
DDR3L SDRAM is a type of dynamic random-access memory that operates at a lower voltage (1.35V) compared to standard DDR3 (1.5V), reducing power consumption by about 20% while maintaining similar performance. It is part of the DDR3 family, which uses double data rate architecture to transfer data on both edges of the clock, achieving high bandwidth. DDR3L is commonly used in embedded systems, networking equipment, and industrial applications where power efficiency and reliability are critical.
Key features include an 8-bank architecture, programmable CAS latency, burst lengths of 8 and 4, on-die termination (ODT), and a 20ns row cycle time. The device supports auto-refresh and self-refresh modes, and includes a temperature sensor for thermal management. The 96-ball FBGA package provides a compact footprint suitable for space-constrained designs.
Technically, the AS4C256M16D3LC-12BIN uses a high-speed CMOS process and features a 16-bit data bus, achieving data rates up to 1600 Mbps per pin. It operates from a single 1.35V supply, with an I/O voltage of 1.35V, and is compatible with JEDEC DDR3L standards. The device includes programmable read and write latencies, and supports DLL (Delay-Locked Loop) for precise timing.
Typical applications include embedded computing, industrial PCs, networking routers, and automotive infotainment systems. Its low voltage and industrial temperature range make it ideal for harsh environments. The device is also suitable for high-reliability systems requiring long-term availability.
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 stable 1.35V supply and careful termination of the data and address lines.

Key Differentiators
- Industrial temperature range (vs MT41K256M16HA-125)

- Drop-in replacement availability (vs AS4C256M16D3LC-12BAN)
Design Notes
Place 0.1uF decoupling capacitors close to each VDD and VDDQ pin, and a 10uF bulk capacitor near the power entry. Follow the layout guidelines in the Alliance Memory datasheet to minimize trace lengths and ensure signal integrity for high-speed DDR3L signals.
The AS4C256M16D3LC-12BIN operates up to +95°C. Ensure adequate airflow or heatsinking in high-temperature environments. The 1.35V supply reduces power dissipation, but thermal vias under the FBGA package can help conduct heat away from the device.
For DDR3L-1600 operation, maintain controlled impedance of 40-50 ohms for data and address lines. Use series termination resistors (22-33 ohms) near the driver to reduce reflections. Keep the clock and strobe pairs tightly coupled and length-matched to minimize skew.
