|Name||Microcontroller I/O Expander (AN 265)|
|Description||Many microcontroller and microprocessors limit I/O ports and pins to conserve pin counts and reduce package sizes. For many microcontroller- (e.g., PIC, 8051, and SX) or microprocessor-based systems, the system design requires more I/O pins without changing the microcontroller. To increase the number of I/O pins without changing the microcontroller, I/O expansion provides a solution. With up to 272 I/O pins and MultiVoltTM I/O capability, Altera® MAX 10 devices allow you to implement microcontroller I/O expansion in microcontroller- or microprocessor based systems. |
A key advantage of using MAX 10 devices as a microcontroller I/O expander is the integration of logic functions across your entire board. The flexibility of a programmable device means that not only can the I/O expansion function be implemented, but other functions can be integrated such as LED drivers or bus-bridging logic. Additionally, with the user flash memory in MAX 10 devices, functions that use memory also can be implemented. This integration allows you to reduce component count across the board, minimizing cost and maximizing board space efficiency.

Note: After downloading the design example, you must prepare the design template. The file you downloaded is of the form of a <project>.par file which contains a compressed version of your design files (similar to a .qar file) and metadata describing the project. The combination of this information is what constitutes a <project>.par file. In releases 16.0 or newer, you can simply double click on the <project>.par file and Quartus will launch that project.
Browse to the <project>.par file you downloaded, click next, followed by Finish, and your design template will be installed and displayed in the Project Navigator pane in Quartus.
Note: When a design is stored in the Design Store as a design template, it has been previously regression tested against the stated version of Quartus software. The regression ensures the design template passes analysis/synthesis/fitting/assembly steps in the Quartus design flow.
At the command-line, type the following command:
Once the process completes, then type:
