H5TC4G63CFR-xxL 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 approximately 20% while maintaining backward compatibility with DDR3-based environments. 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 commonly used in laptops, embedded systems, and networking equipment where power efficiency is critical.
Key features of the H5TC4G63CFR-xxL include a 4Gb density, 256M x 16 organization, 1.35V power supply, and support for data rates up to 2133 Mbps (depending on the speed grade). The device offers low power consumption, with a typical operating current of and standby current of . It also features on-die termination (ODT), programmable CAS latency, and burst lengths of 8 and 4 (with burst chop). The device is designed for reliable operation over a temperature range of .
The H5TC4G63CFR-xxL utilizes advanced DRAM process technology, providing high density and performance while minimizing power consumption. The 96-pin FBGA package offers excellent thermal and electrical characteristics, supporting high-speed signaling with minimal parasitic inductance. The device includes auto-refresh and self-refresh modes to maintain data integrity with minimal power draw.
Typical applications include main memory for laptops and ultrabooks, embedded systems, networking equipment, and industrial computing. The low voltage and high bandwidth make it suitable for power-sensitive designs that require high performance. The device is also used in memory modules and system-on-module (SoM) designs.
When designing with this component, ensure proper decoupling capacitors are placed near the power pins to minimize noise. The DDR3L interface requires careful PCB layout to maintain signal integrity, including matched trace lengths and controlled impedance.

Key Differentiators
- Low voltage operation at 1.35V (vs K4B4G1646E-BYMA)
- Lead-free and halogen-free (vs MT41K256M16TW-107)
- Same-brand drop-in availability (vs K4B4G1646E-BYMA)
Design Notes
For DDR3L memory, maintain controlled impedance of 40-50 ohms for data lines and 50-60 ohms for address/control lines. Keep trace lengths matched within 100 mils to ensure signal integrity. Use a solid ground plane and place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin.
The H5TC4G63CFR-xxL operates at 1.35V, which is lower than standard DDR3. Ensure the power supply provides stable 1.35V with low ripple. Use a dedicated voltage regulator for the memory rail and place bulk capacitors (10uF) near the device to handle transient currents.
Although DDR3L consumes less power than DDR3, thermal management is still important. Ensure adequate airflow or a heatsink if the device is used in high-temperature environments. The FBGA package has a thermal resistance of [DATA_NEEDED: theta_JA], so calculate junction temperature to avoid exceeding the maximum rating.
