The Arduino MEGA 2560 is a very popular and versatile Microcontroller board. Along with powerful I/O functionality, it offers 256K of program storage and 8K of internal SRAM. The small amount of SRAM is adequate for basic designs but can lead to low-memory issues when using the MEGA 2560 in more sophisticated applications.
Solution:
Plug-on the XMEM+ to upgrade your MEGA 2560
Increase SRAM up to 512K
Use the added SRAM for expanded internal stack space, more variable storage, extra-large arrays, and deep buffers. The external SRAM is organized as 16 banks of 32K each. The active 32K bank seamlessly follows the internal 8K SRAM, making a total of 40K available at any moment. On-Board high-speed logic simplifies bank-switching management.
Parallel Expansion Bus
Develop custom parallel type circuitry using the Expansion Bus. This 23K area is true Arduino MEGA 2560 memory space, no performance wasting "Bit-Banging" required. It directly supports all native software instructions and runs at full system speed. Buffered Control, Data, and Address signals are fully accessible for off-board prototyping. In addition, the operating logic level for all buffered signals is configurable as 3.3V or 5V which makes working with modern mixed voltage circuitry easy and straightforward.
