PIC12F1822-E

8/14-Pin Flash Microcontrollers with nanoWatt XLP Technology

Microchip Technology 

PIC12F/LF1822/16F/LF1823

3.0 MEMORY ORGANIZATION

There are three types of memory in

PIC12F/LF1822/16F/LF1823 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”.

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 PIC12F/LF1822/16F/LF1823

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 Figures 3-1 and ).
