The maximum memory capacity of the 8086 microprocessor is 1 megabyte (MB). This limitation arises from its 20-bit address bus, which allows it to address up to 2^20 memory locations, equating to 1,048,576 bytes or 1 MB. The memory is organized into segments, with the segmentation scheme allowing for more efficient memory management within this address space.
