AS4C256M16D3L-12BCNTR Overview
DDR3L (Double Data Rate 3 Low Voltage) SDRAM is a type of synchronous dynamic random-access memory that operates at a reduced supply voltage of 1.35V, compared to standard DDR3's 1.5V, reducing power consumption by up to 20% while maintaining similar performance. It is part of the DDR3 memory family, which uses double-data-rate signaling to transfer data on both edges of the clock, achieving high bandwidth. DDR3L is widely used in mobile devices, embedded systems, and networking equipment where power efficiency is critical.
Key features include a parallel interface with 16-bit data bus, 800 MHz clock speed, 20 ns access time, and support for 1.283V to 1.45V supply voltage. The device is RoHS compliant and lead-free, meeting environmental standards. The 96-FBGA package with 9x13mm dimensions provides a compact footprint suitable for space-constrained PCB designs.
Technically, the AS4C256M16D3L-12BCNTR utilizes advanced DRAM process technology to achieve high density and low power. It supports burst lengths of 8 and 4, on-die termination (ODT), and programmable CAS latency. The device includes auto-refresh and self-refresh modes for power saving. The 1.35V operation reduces I/O power, making it ideal for battery-powered applications.
Typical applications include servers, workstations, networking equipment, and embedded systems requiring high-capacity, low-power memory. The 4Gbit density and 16-bit organization make it suitable for memory expansion in industrial PCs, routers, and test equipment.
When designing with this component, 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 reference voltage (VREF) for reliable operation.

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 for DQ and address lines, ensuring signal integrity at 800 MHz.
The AS4C256M16D3L-12BCNTR operates up to +95°C. Ensure adequate airflow or heatsinking in high-temperature environments. The 1.35V supply reduces power dissipation, but verify the thermal profile in your system.
Do not exceed the supply voltage range of 1.283V to 1.45V. Ensure the VREF voltage is properly generated and decoupled. Incorrect termination of address/control lines can cause data corruption. Refer to the datasheet for ODT settings.
