PIC16LC72A-04IP

28-Pin 8-Bit CMOS Microcontrollers

Microchip Technology 

2.0 MEMORY ORGANIZATION

There are two memory blocks in each of these micro-

controllers. Each block (Program Memory and Data

Memory) has its own bus, so that concurrent access

can occur.

Additional information on device memory may be found

in the PICmicro™ Mid-Range Reference Manual,

(DS33023).

2.1 Program Memory Organization

The PIC16C62B/72A devices have a 13-bit program

counter capable of addressing an 8K x 14 program

memory space. Each device has 2K x 14 words of pro-

gram memory. Accessing a location above 07FFh will

cause a wraparound.

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

at 0004h.
