In-System Reprogrammable Flash Program Memory
This section describes the different memories in the ATmega165P. The AVR architecture has
two main memory spaces, the Data Memory and the Program Memory space. In addition, the
ATmega165P features an EEPROM Memory for data storage. All three memory spaces are lin-
ear and regular.
The ATmega165P contains 16 Kbytes On-chip In-System Reprogrammable Flash memory for
program storage. Since all AVR instructions are 16 or 32 bits wide, the Flash is organized as 8K
x 16. For software security, the Flash Program memory space is divided into two sections, Boot
Program section and Application Program section.
The Flash memory has an endurance of at least 10,000 write/erase cycles. The ATmega165P
Program Counter (PC) is 13 bits wide, thus addressing the 8K program memory locations. The
operation of Boot Program section and associated Boot Lock bits for software protection are
described in detail in
