4.0 MEMORY ORGANIZATION

4.1 Program Memory Organization

The PIC16C71X family has a 13-bit program counter

capable of addressing an 8K x 14 program memory

space. The amount of program memory available to

each device is listed below:

Device

Program

Memory

Address Range

PIC16C710

PIC16C71

PIC16C711

PIC16C715

512 x 14

1K x 14

1K x 14

2K x 14

0000h-01FFh

0000h-03FFh

0000h-03FFh

0000h-07FFh

For those devices with less than 8K program memory,

accessing a location above the physically implemented

address will cause a wraparound.

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

at 0004h.
