CXDB5CCAM-MK 概要
LPDDR4X (Low Power Double Data Rate 4X) is a type of synchronous dynamic random-access memory (SDRAM) optimized for low power consumption and high data rates, commonly used in smartphones, tablets, and embedded systems. It is part of the LPDDR memory family, which evolved from DDR to provide reduced voltage and power for mobile applications. LPDDR4X operates at a lower I/O voltage (0.6V) compared to LPDDR4 (1.1V), enabling significant power savings while maintaining high bandwidth.
Key features of the CXDB5CCAM-MK include support for asynchronous reset, data mask function, and ZQ calibration, which are essential for reliable memory operation. The device is RoHS compliant, ensuring environmental safety. The BGA200 package offers a compact footprint suitable for space-constrained designs, and the -25°C to +85°C operating temperature range supports both commercial and industrial applications.
Technically, the CXDB5CCAM-MK is a 8Gb (gigabit) LPDDR4X device, organized as 512M x 16, providing a 16-bit data bus. It supports data rates up to 4266 Mbps, delivering high bandwidth for demanding applications. The memory uses a 1.1V core voltage and 0.6V I/O voltage, reducing power consumption by up to 40% compared to LPDDR4. The device includes on-die ECC and supports deep power-down mode for extended battery life.
Typical applications include smartphones, tablets, AI edge devices, and automotive infotainment systems. The CXDB5CCAM-MK is also used in Rockchip RK3588S-based systems, where it provides the necessary memory bandwidth for high-resolution displays and AI processing. Its low power consumption makes it ideal for battery-powered devices.
When designing with this memory, ensure proper PCB layout for high-speed signals, including impedance matching and minimal trace lengths. Use the ZQ calibration feature to optimize signal integrity. The device supports a wide range of operating conditions, but careful attention to power supply decoupling is recommended to maintain stable operation.

設計ノート
For high-speed LPDDR4X signals, maintain 50-ohm single-ended and 100-ohm differential impedance. Keep trace lengths matched within 0.5mm for DQ/DQS groups. Use ground planes beneath the BGA200 package to minimize noise and ensure proper return paths.
Decouple VDD1 and VDDQ with 0.1uF and 1uF capacitors placed as close to the balls as possible. Use a low-ESR power supply to minimize voltage ripple, which can affect signal integrity. Consider a dedicated power plane for VDDQ to reduce noise.
The CXDB5CCAM-MK operates up to +85°C. Ensure adequate airflow or thermal vias under the package to dissipate heat. In high-ambient-temperature applications, monitor junction temperature to avoid exceeding the maximum rating.
