PIC microcontrollers Chip Resources

Easy Comparison of PIC microcontrollers
using bubble diagrams...

The following bubble diagrams let you easily view and compare PIC Microcontroller's resources; showing you:

• Program memory.
• RAM.
• EEPROM.
• All Peripherals at a glance.

The microcontrollers shown here especially 12F675, 16F88 and 16F877 are frequently used on this site as they provide good all round features and, importantly, they are all flash erasable and re-programmable.

Note: The 16F84 is provided for comparison as it is a nearly obsolete chip (but well known).  If you are starting out then a better choice would be the 16F88 which has the same pinout (extended) but many more features. For ease of use use a 16F877A as there are more pins making it easier for prototyping.

Comparing microcontroller diagrams

Use any tab capable browser e.g. Chrome or Firefox.

To compare device features open each link below in a new tab window (right click on the link and select 'open link in new Tab').  Then in each page click on the 'bubble diagram' link.  

Then simply select the tabs for the devices you are interested in - since the diagrams are designed to be similar you can easily identify the differences between each device e.g. if there is a peripheral that is not available in one device compared to the other there will be a blank space.

If you don't use a tabbed browser then just overlay new browser windows.
