There are three memory types in Enhanced MCU
devices. These memory types are:
• Program Memory
• Data RAM
• Data EEPROM
Data and program memory use separate busses which
allow for concurrent access of these types.
Additional detailed information for Flash program mem-
ory and data EEPROM is provided in Section 6.0
“Flash Program Memory” and Section 7.0 “Data
EEPROM Memory”, respectively.

5.1
A 21-bit program counter is capable of addressing the
2-Mbyte program memory space. Accessing a location
between the physically implemented memory and the
2-Mbyte address will cause a read of all ‘0’s (a NOP
instruction).
The PIC18F2220 and PIC18F4220 each have
4 Kbytes of Flash memory and can store up to 2,048
single-word instructions.
The PIC18F2320 and PIC18F4320 each have
8 Kbytes of Flash memory and can store up to 4,096
single-word instructions.
The Reset vector address is at 0000h and the interrupt
vector addresses are at 0008h and 0018h.
The Program Memory Maps for PIC18F2220/4220 and
PIC18F2320/4320 devices are shown in Figure 5-1
and Figure 5-2, respectively.
