K4B4G1646D-BCMA0 Visão geral
DDR3 SDRAM (Double Data Rate Type 3 Synchronous Dynamic Random Access Memory) is a type of volatile memory that transfers data on both edges of the clock, doubling the data rate compared to DDR2. It features a prefetch buffer of 8n, enabling high bandwidth while operating at lower voltages (1.5V) than previous generations. DDR3 is widely used in PCs, servers, and embedded systems where high speed and capacity are required.
Key features include a 256M x 16 organization, 1866 Mbps data rate, and 1.5V supply voltage. The device supports auto precharge, asynchronous reset, ZQ calibration, data mask, and dynamic on-chip termination (DTC), enhancing signal integrity and system reliability. The 96-ball FBGA package provides a compact footprint suitable for space-constrained designs.
Technically, the K4B4G1646D-BCMA0 utilizes Samsung's advanced DRAM process technology, ensuring low power consumption and high-speed operation. The D-die revision offers improved timing margins and reduced latency compared to earlier dies. The device operates over a temperature range of 0°C to 85°C, making it suitable for commercial and industrial applications.
Typical applications include main memory in laptops and desktops, networking equipment such as routers and switches, and embedded systems like set-top boxes and industrial controllers. Its high density and speed make it ideal for applications requiring large memory footprints and fast data access.
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 is RoHS compliant and halogen-free, meeting environmental standards.
