Technical Guide: How to Select, Design In, and Use the CXDB5CCAM-MK

Understanding the LPDDR4X Interface

The CXDB5CCAM-MK is a low-power double data rate 4X memory, optimized for mobile and embedded applications. Its 0.6V I/O voltage (VDD2) reduces power consumption significantly compared to LPDDR4's 1.1V I/O, while the 1.1V core (VDD1) maintains performance. The device supports asynchronous reset, data mask, ZQ calibration, and on-die ECC, ensuring reliable operation in demanding environments.

Selecting the Right Memory for Your Application

When selecting the CXDB5CCAM-MK, verify that your system's memory controller supports LPDDR4X at 4266 Mbps. The 512M x 16 organization provides a 16-bit data bus, which is typical for mid-range mobile processors. For higher bandwidth, consider multiple devices or a wider bus. The BGA200 package requires careful PCB layout for high-speed signals.

Designing with the CXDB5CCAM-MK

Follow these guidelines for a successful design:

  • Power Supply Decoupling: Place 0.1µF and 1µF capacitors close to each VDD1 and VDDQ pin to maintain stable voltage.
  • Signal Integrity: Match trace impedances (typically 50Ω single-ended, 100Ω differential) and keep trace lengths minimal for DQ, DQS, and clock signals.
  • ZQ Calibration: Connect a 240Ω ±1% resistor to the ZQ pin and perform calibration during initialization to optimize signal integrity.
  • Thermal Management: The -25°C to +85°C range covers most commercial and industrial environments; ensure adequate airflow or heatsinking if operating near the upper limit.
  • Reset and Clock: Use the asynchronous reset (RESET#) to initialize the device, and provide a clean differential clock (CK/CK#) with proper termination.

Using the CXDB5CCAM-MK in Rockchip RK3588S Systems

The CXDB5CCAM-MK is commonly used in Rockchip RK3588S-based systems, providing the memory bandwidth needed for high-resolution displays and AI processing. Ensure your RK3588S design's memory controller is configured for LPDDR4X and that the PCB layout meets the manufacturer's recommendations.
