The manufacturer ordering information and package drawing should be checked before assigning this memory to a processor or memory-controller platform, particularly when a different package or suffix is listed.
cxdb4abam emmc
CXDB4ABAM-MK is LPDDR4X volatile SDRAM, not eMMC storage. LPDDR4X is connected to the processor memory controller as main working memory, while eMMC is a nonvolatile storage device used for persistent files and applications. The CXDB4ABAM-MK provides 8Gb at 3733 MHz with 0.6 V VDDQ, while an eMMC device serves a separate storage function and requires a different interface and protocol.
Where can I download the CXDB4ABAM-MK datasheet PDF?
The CXDB4ABAM-MK datasheet is linked in the datasheet field on this page and identifies the CXMT LPDDR4X SDRAM documentation. The document covers ordering information, device decoding, electrical characteristics, input timing, output-driver behavior, and package information. Use the manufacturer document when assigning balls, planning power rails, selecting decoupling, or configuring the host memory controller.
Where can I find the CXDB4ABAM-MK pinout?
Use the ball-assignment and package-drawing sections of the CXMT LPDDR4X SDRAM datasheet for the CXDB4ABAM-MK pin map. The device uses a 200-ball FBGA package, and its complete ball numbering cannot be reconstructed safely from a distributor summary. Before PCB routing, verify every command, address, clock, data, and supply ball against the exact ordering option and package revision shown in the manufacturer document.
What is the best drop-in replacement for CXDB4ABAM-MK?
No drop-in replacement for CXDB4ABAM-MK has been established from the available cross-reference information. An LPDDR4X memory is not interchangeable solely because it uses the same BGA family: density, timing, command support, ball mapping, voltage domains, and host-controller initialization must all match. CXDB4ABAM-ML and CXDB4CCAM-MJ are possible CXMT-family candidates, but the manufacturer documentation must confirm pin and parameter compatibility before either is treated as a drop-in substitute.
Can another CXMT LPDDR4X part replace CXDB4ABAM-MK?
A CXMT LPDDR4X part can replace CXDB4ABAM-MK only after its ordering code, package, ball map, density, speed grade, and timing parameters are verified. CXDB4ABAM-ML is identified as a similar CXMT-family listing, but that relationship alone does not prove drop-in compatibility. The CXMT ordering table, package drawing, and device datasheet should be compared with the incumbent memory before a substitution is approved.
When should I choose CXDB4ABAM-MK instead of another LPDDR4X device?
Choose CXDB4ABAM-MK when the design requires an 8Gb LPDDR4X device with a 3733 MHz data rate, 0.6 V VDDQ, dual-channel support, and a 200-ball FBGA footprint. Select another device when its density, timing, ball assignment, power behavior, or package matches the host platform better. Processor support, PCB constraints, and thermal performance should determine the final choice rather than data rate alone.
Is CXDB4ABAM-MK suitable for mobile and embedded applications?
Yes, CXDB4ABAM-MK is suitable for mobile and embedded systems that support LPDDR4X memory. Its 8Gb density, 3733 MHz data rate, 0.6 V I/O supply, and operating modes including standby and deep power-down align with compact, power-sensitive products. The host platform must provide compatible LPDDR4X training and power-management support, and the PCB must meet the high-speed routing and decoupling requirements.
What are the key specifications of CXDB4ABAM-MK that engineers should know?
The key CXDB4ABAM-MK specifications are 8Gb density, 3733 MHz LPDDR4X operation, 1.8 V VDD1, 1.1 V VDD2, 0.6 V VDDQ, dual-channel operation, and a 16n prefetch architecture. According to the CXMT LPDDR4X datasheet, the device also supports on-die termination, deep power-down, and temperature-compensated self-refresh. It uses a 15 × 10 × 0.8 mm 200-ball FBGA package and is RoHS compliant.
What is the difference between CXDB4ABAM-MK and CXDB4CCAM-MJ?
CXDB4ABAM-MK and CXDB4CCAM-MJ are different CXMT LPDDR4X ordering codes, so their ordering-table parameters must be compared before substitution. CXDB4ABAM-MK is identified as an 8Gb, 3733 MHz device in a 200-ball FBGA package, while the corresponding CXDB4CCAM-MJ density, speed grade, and electrical differences are not confirmed in the cross-reference information. Do not treat the shared memory family as proof of pin-to-pin equivalence.
What is the best Micron equivalent for CXDB4ABAM-MK?
No Micron drop-in equivalent for CXDB4ABAM-MK is established by the cross-reference information. A Micron LPDDR4X device would need matching density, package dimensions, ball map, command set, timing, voltage domains, and host-controller support to serve as a true drop-in replacement. Cross-brand memory substitution normally requires board changes or careful firmware and electrical validation, so the original CXMT package drawing must be used as the comparison baseline.
How are CXDB4ABAM-MK power rails decoupled?
Place the VDD1, VDD2, and VDDQ bypass capacitors directly beside their respective FBGA supply and ground balls, following the capacitor values and placement rules in the CXMT datasheet. Keep power-loop paths short and provide a low-impedance reference plane for high-speed signals. Stable rails, correct sequencing, and minimized package-to-decoupling inductance are essential because the device supports a 3733 MHz data rate.
Is CXDB4ABAM-MK in stock, and what is its lead time?
Current stock and lead time for CXDB4ABAM-MK should be requested through the Request a Quote form on this page. A distributor listing marked in stock does not establish XAIPART inventory, current lot traceability, or a delivery commitment. Provide the required quantity, date-code preference, destination, and qualification status when requesting a quotation so the memory order can be reviewed against the exact CXDB4ABAM-MK suffix.
Where can I buy CXDB4ABAM-MK?
Use the Request a Quote form on this page to request CXDB4ABAM-MK supply, current price, stock status, and lead time. The manufacturer ordering suffix identifies a specific 8Gb LPDDR4X configuration in a 200-ball FBGA package, so a quotation should request the exact CXDB4ABAM-MK MPN rather than a generic LPDDR4X device. Include lot, traceability, and delivery requirements for production purchasing.
