Shown customized without power supply
Have you tried to learn PIC programming and been put off by banking and the minimalist instruction set? Are you an experienced PIC programmer looking for a more powerful PIC? Then the APP-III is for you! Although the PIC 16F-series is very popular, it has many limitations that make it hard to learn and even harder to use. Microchip's 18F series has many powerful features including:
Now with the APP-III you can quickly and easily develop programs for this powerful processor. You don't need a Programmer! Look at these great features:
|Supports MPLAB the free assembler/development environment from Microchip (or any tool that generates 8-bit hex files)|
|Up to 22 digital I/O ports (19 unrestricted)|
|Full serial port available to your program|
|5 channels of 10-bit A/D|
|1.5K bytes of RAM|
|256 bytes of EEPROM|
|15.8K of program words (32Kbytes - 512 bytes)|
|Can connect directly to a solderless breadboard|
|Self-contained 7805 regulator on PC board|

Please note that this is a kit and does require soldering and basic electronic tools. This allows you to customize the board to fit your needs. All the parts are through hole, and the solder masked board is very easy to assemble.
Q: What are the differences between the APP-III and an ordinary PIC18F252?
A: The APP-III doesn't require a programmer. However, this also means that there are a few differences. In particular, your program starts at location 0x200 (with interrupt vectors at 0x208 and 0x218). Port B pin 7 is not generally available for your use. You must use a HS-mode clock. Your program is free to use the serial port, but you should refrain from using the two serial port pins as general-purpose I/O unless you disconnect them before programming.
Q: Can I program a regular PIC with my APP-III code?
A: Yes. An APP-III program will run on any PIC18F252 (or similar processor). You simply include a stub to replace the bootloader or rebase your code from location 0 instead of 0x200.
Q: Can you supply the APP-III on other PIC18F chips?
A: Yes, by special order. Minimum quantity restrictions may apply.
Q: Does the APP-III support 16F parts?
A: No. But the APP-II does.
Q: Can I refit an APP-II or GPMPU28 to use the APP-III chip?
A: Yes. However, the programming jumper is in a different location. You will have to add a two-pin header to your board in a different location.
