Overview (Abstract):

The CXDB4CBAM-MK-A is a low-power, high-speed SDRAM (Synchronous Dynamic Random-Access Memory) device manufactured by ChangXin Memory Technologies (CXMT) , a leading Chinese DRAM developer. Designed for mobile and embedded applications, this device integrates 16 Gigabits (2 Gigabytes) of memory in a compact FBGA-200 (Fine-Pitch Ball Grid Array) package .

Operating from a 1.7V to 1.95V power supply for I/O and a 1.1V core voltage, the CXDB4CBAM-MK-A implements the LPDDR4X interface standard. It achieves a maximum clock frequency of 1.866 GHz, supporting data rates up to 3733 Mbps per pin . The device is specified for an operating temperature range of -25°C to +85°C .

Market Status: Please note that this part number is listed as "Discontinued" or "End of Life" by major component distributors . It is recommended to verify availability with authorized suppliers or consider newer CXMT LPDDR4X offerings for new designs.
