H5TC4G63CFR-xxJ - 4Gb DDR3L SDRAM 256Mx16 | SK Hynix
MPN: H5TC4G63CFR-xxJ ✓ AktifH5TC4G63CFR-xxJ Ringkasan
DDR3L SDRAM (Double Data Rate 3 Low Voltage) is a type of synchronous dynamic random-access memory that transfers data on both rising and falling edges of the clock signal, effectively doubling the data rate. DDR3L operates at 1.35V, reducing power consumption by about 20% compared to standard DDR3 (1.5V), while maintaining compatibility with DDR3 signaling levels. It is part of the memory hierarchy in computing systems, serving as main memory for processors, and is widely used in laptops, servers, and embedded applications.
Key features include a 4Gb density, 16-bit I/O width, and support for various speed grades (e.g., -xxJ indicates a specific speed grade, likely 1600 Mbps or 1866 Mbps). The device uses a 96-ball FBGA package, which is standard for DDR3L SDRAM, ensuring compatibility with existing PCB designs. The operating temperature range is from 0°C to 95°C (case temperature), and it supports auto-refresh and self-refresh modes for power saving.
Technically, the H5TC4G63CFR-xxJ employs an 8n-prefetch architecture, which allows high-speed data transfer by fetching 8 data bits per clock cycle per I/O. It includes programmable CAS latency, burst length (8 and 4 with burst chop), and on-die termination (ODT) for signal integrity. The device also supports write leveling and read leveling for improved timing margins in high-speed systems.
Typical applications include main memory for laptops, ultrabooks, and embedded systems, as well as networking equipment like routers and switches, and industrial computing platforms. Its low voltage and high density make it suitable for power-constrained designs that require large memory capacity.
When designing with this component, ensure proper decoupling capacitors near the VDD and VDDQ pins, and follow the DDR3L layout guidelines for signal integrity, including impedance matching and length matching for data and address lines. The device requires a stable 1.35V supply and a reference voltage (VREF) for the command/address bus.
