3.0 MEMORY ORGANIZATION

There are three types of memory in

PIC16(L)F1824/1828 devices: Data Memory, Program

Memory and Data EEPROM Memory(1).

• Program Memory

• Data Memory

- Core Registers

- Special Function Registers

- General Purpose RAM

- Common RAM

- Device Memory Maps

- Special Function Registers Summary

• Data EEPROM memory(1)

Note 1: The data EEPROM memory and the

method to access Flash memory through

the EECON registers is described in

Section 11.0 “Data EEPROM and Flash

Program Memory Control”.

PIC16(L)F1824/1828

The following features are associated with access and

control of program memory and data memory:

• PCL and PCLATH

• Stack

• Indirect Addressing

3.1 Program Memory Organization

The enhanced mid-range core has a 15-bit program

counter capable of addressing a 32K x 14 program

memory space. Table 3-1 shows the memory sizes

implemented for the PIC16F/LF1824/1828 family.

Accessing a location above these boundaries will cause

a wrap-around within the implemented memory space.

The Reset vector is at 0000h and the interrupt vector is

at 0004h (see Figure 3-1).
