K4B4G1646D-BYH90 - 4Gb DDR3L SDRAM x16 96FBGA | Samsung
MPN: K4B4G1646D-BYH90 ✓ Hoạt độngK4B4G1646D-BYH90 Tóm tắt
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 up to 20% while maintaining similar performance. It is part of the DDR3 SDRAM family, which uses double data rate architecture to transfer data on both edges of the clock, and is widely used in computing, networking, and embedded systems where high bandwidth and low power are critical.
Key features include programmable CAS latency (CL) and CWL, on-die termination (ODT) using the ODT pin, internal self-calibration via ZQ calibration, and asynchronous reset. The device supports auto precharge, data mask, and dynamic on-chip termination, enhancing signal integrity and simplifying system design. It is lead-free and halogen-free, RoHS compliant, and operates over a temperature range of 0°C to +85°C.
The K4B4G1646D uses a D-die process and is available in a 96-ball FBGA package (ball pitch 0.8mm), providing a compact footprint for space-constrained designs. The device includes a programmable output driver impedance and supports DLL (Delay Locked Loop) for precise timing. It also features a temperature-compensated self-refresh (TCSR) mode to reduce power in standby.
Typical applications include DDR3L memory modules for laptops, embedded systems, networking equipment, and industrial computing. Its low voltage and high speed make it ideal for battery-powered devices and high-performance computing platforms. The device is also suitable for use in servers and storage systems where reliability and efficiency are paramount.
When designing with this device, ensure proper decoupling capacitors near the power pins and follow the PCB layout guidelines in the datasheet to maintain signal integrity at 2133 Mbps. The ZQ pin requires a 240-ohm resistor to ground for calibration, and the VREFCA and VREFDQ should be properly bypassed.

Ghi chú thiết kế
For reliable operation at 2133 Mbps, maintain controlled impedance for DQ, DQS, and address/command traces. Use 40-60 ohm single-ended and 80-120 ohm differential impedance. Keep trace lengths matched within +/- 0.5mm for DQ/DQS groups. Place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin, and a 10uF bulk capacitor near the device. Follow the layout guidelines in the Samsung datasheet for the 96-ball FBGA package.
The K4B4G1646D-BYH90 operates from a 1.35V supply (VDD) and 1.35V I/O supply (VDDQ). Ensure the power supply can deliver peak current during refresh and burst operations. Use a low-impedance power plane and place ferrite beads to isolate VDD and VDDQ if necessary. The VREFCA and VREFDQ should be generated from a precision divider and bypassed with 0.1uF capacitors. Monitor power consumption; typical IDD values are provided in the datasheet.
Do not exceed the absolute maximum ratings for VDD (1.45V) and VDDQ (1.45V). Ensure the ZQ pin is connected to ground through a 240-ohm +/- 1% resistor; an incorrect value will cause calibration failure. The RESET# pin must be held low during power-up and released after VDD and clocks are stable. Avoid floating the ODT pin; tie it to VDD or VSS as needed. Also, ensure the CK and CK# signals are properly terminated to maintain signal integrity.
