Description
PIC18FX58 devices have twice the Flash program memory and data RAM of PIC18FX48 devices (32 Kbytes and 1536 bytes vs. 16 Kbytes and 768 bytes, respectively). 2. PIC18F2X8 devices implement 5 A/D channels, as opposed to 8 for PIC18F4X8 devices. 3. PIC18F2X8 devices implement 3 I/O ports, while PIC18F4X8 devices implement 5. 4. Only PIC18F4X8 devices implement the Enhanced CCP module, analog comparators and the Parallel Slave Port.
