+==== PIC ====
+The Microchip PIC18F series chips are used as the main microprocessor in the Core module. Details regarding the chips are as follows:
+=== 18F452 (I/P) ===
+[[:home:mbhp:pic:18F452]]
+  * About - This is the original chip used for MIOS/MBHP projects
+  * Basic Specs -
+  * Pros/Cons - Simple, widely used, but lacks some features seen in newer PIC18F variants
+=== 18F4620 ===
+[[:home:mbhp:pic:18F4620]]
+  * About - Almost identical to the '452, but with expanded codespace and RAM.
+  * Basic Specs -
+  * Pros/Cons - Should work wherever a '452 is specified, and also used in other apps such as MBSEQv3 where extra RAM is useful. Beware early revesions of this chip may suffer from the EUSART bug.
+=== 18F4685 ===
+[[:home:mbhp:pic:18F4685]]
+  * About - A more recent PIC18F with similar codespace and RAM to the '4620, but with some added peripherals.
+  * Basic Specs
+  * Pros/Cons - Contains a CAN buss peripheral for fast inter-processor communications >1Mbps and implementation of [[#MBNet]]. Slightly less codespace and RAM compared to the '4620, to accomodate these features. RAM handling differs from the 452/4620, so not all apps are compatible.
