PIC18F66K80 FAMILY
6.0 MEMORY ORGANIZATION
PIC18F66K80 family devices have these types of
memory:
• Program Memory
• Data RAM
• Data EEPROM
As Harvard architecture devices, the data and program
memories use separate busses. This enables
concurrent access of the two memory spaces.
The data EEPROM, for practical purposes, can be
regarded as a peripheral device because it is
addressed and accessed through a set of control
registers.
Additional detailed information on the operation of the
Flash program memory is provided in Section 7.0
“Flash Program Memory”. The data EEPROM is
discussed separately in Section 8.0 “Data EEPROM
Memory”.
