CXDB4ABAM-MK Overview
LPDDR4X (Low Power Double Data Rate 4X) is a type of synchronous dynamic random-access memory (SDRAM) designed for mobile and embedded systems. It is an evolution of LPDDR4, offering higher data rates and lower power consumption through reduced I/O voltage (0.6V). LPDDR4X is part of the broader DRAM memory hierarchy, which includes DDR4, DDR5, and LPDDR5, and is specifically optimized for power-sensitive applications such as smartphones, tablets, and IoT devices.
Key features of the CXDB4ABAM-MK include a 3733 MHz data rate, 8Gb density, and support for dual-channel operation. The device operates from a 1.8V VDD1 and 1.1V VDD2 power supply, with a VDDQ of 0.6V for the I/O, reducing power consumption by up to 20% compared to LPDDR4. It supports various operating modes including active, standby, and deep power-down, enabling efficient power management. The package is RoHS compliant, meeting environmental standards.
The CXDB4ABAM-MK utilizes advanced process technology to achieve high speed and low power. It features on-die termination (ODT) for improved signal integrity and supports a 16n prefetch architecture, which enhances data throughput. The device includes a temperature-compensated self-refresh (TCSR) mechanism to maintain data integrity across a wide temperature range. The 200-ball FBGA package provides excellent thermal dissipation and is suitable for space-constrained designs.
Typical applications include smartphones, tablets, set-top boxes, and IoT devices. In smartphones, the high data rate enables smooth multitasking and immersive VR experiences. In set-top boxes, it supports high-definition video streaming and fast app loading. The low power consumption extends battery life in portable devices.
When designing with this device, ensure proper decoupling capacitors are placed near the power pins to minimize noise. The device requires a stable power supply and careful PCB layout to maintain signal integrity at 3733 MHz. Refer to the datasheet for detailed layout guidelines.

Design Notes
For high-speed LPDDR4X signals at 3733 MHz, maintain controlled impedance of 50 ohms for single-ended and 100 ohms differential for clock signals. Keep trace lengths matched within 0.1mm for data and address buses. Use ground planes beneath the memory to minimize noise.
Decouple VDD1 (1.8V) and VDD2 (1.1V) with 0.1uF and 1uF capacitors placed as close to the pins as possible. Use a 4.7uF bulk capacitor on the power rail. Ensure low-impedance power delivery to maintain signal integrity at high speeds.
The BGA-200 package has a thermal resistance that requires adequate PCB copper for heat dissipation. Provide thermal vias under the package to the ground plane. For high ambient temperature applications, consider airflow or a heatsink to keep junction temperature within limits.
