Pin-sharing Resolution

Resolving pin-sharing conflicts

Gopher PC is the one and only MCU search engine that accounts for pin-sharing in a search request. This feature automatically takes into account when multiple peripherals are assigned to the same physical package pin, and prevents the selection of parts that have shared functional use on the same pin.

The Gopher database has knowledge of the pin requirements for each functional block (e.g. ADC, DAC, UART, ROM, RAM, TIMER, etc) as well as whether the pin requirements of those functional blocks overlap.

Let’s say you need two A/D inputs and 10 general purpose I/Os (GPIO). Gopher PC first determines if the A/D requirement is using a shared-pin with a GPIO, and if so, it deducts the A/D input from the available GPIO total count for the part being evaluated. In this way pin conflicts are caught upfront and pin conflict MCUs are eliminated from the search since they cannot be used for the desired design project.

This "Pin Sharing Resolution" feature works with the following parameters:
      A/D channels (including differential inputs) (effects GPIOs)
      D/A channels (effects GPIOs)
      Analog Comparisons (effects GPIOs)
      Timer Compares (effects GPIOs and number of Timers)
      Timer Captures (effects GPIOs and number of Timers)
      External I/O Triggers (effects GPIOs)
      UARTs, CAN, LIN, I2C, SCI and SPI interface requirements (effects GPIOs)

Searchable across all major MCU manufacturers

Are you tired of having to search for MCU's via individual manufacturers' databases? GOPHER PC's database of search parameters is extensive and consistent and can search simultaneously across all major manufacturers (see Manufacturers in Database).

3

Consistency in the searchable parameters

The parametric data for each parameter is consistently described and searchable - e.g. standardization of all parameter headings along with normalization of all data for each of the parameters, allowing for concise searches across all MCU manufacturers.

Narrowing search by eliminating unwanted MCU features

If too many MCU parts are returned from a search, this proprietary feature helps limit the output to a manageable number of parts. User can reduce the number of search returns to show ONLY those parts that represent the best fit according to their pre-set preferences. That is, the search can be narrowed iteratively by eliminating unnecessary functionality that is either unwanted or unneeded.

5

No limits on search criteria

Searches allow as many parameters as necessary to be specified at the same time.

Quick response

The search engine provides quick responsive searches (matter of seconds) regardless of the volumes of data being searched - e.g. number of manufacturers, MCU parts and/or number of parameters.
