7.0 Atmel AVR 328P Subsystem
Figure 7.1 – The AVR 328P Subsystem (not including SPI mux).
Referring to Figure 7.1, you can see the schematic refers to the ATMega 168 in the notation, this is because the 168 and
328 are 100% compatible, but the 328P has 2X the FLASH and RAM. Thus, when we started the design only the 168 was
available. Moving on, the chip is very simple to interface, just power and an external XTAL (which is removable) at 16
MHz. Take note of the SPI interface lines on the right, these are very important since they are used to communicate with
the Propeller chip as well as the on board 1MB FLASH.
