5.0
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 allows 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.

PIC18F2331/2431/4331/4431
Preliminary
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 PIC18F2331/4331 devices each have 8 Kbytes of
Flash memory and can store up to 4,096 single-word
instructions.
The PIC18F2431/4431 devices each have 16 Kbytes
of Flash memory and can store up to 8,192 single-word
instructions.
The Reset vector address is at 000000h and the
interrupt vector addresses are at 000008h and
000018h.
The program memory maps for PIC18F2331/4331 and
PIC18F2431/4431 devices are shown in Figure 5-1
and Figure 5-2, respectively.
