This section describes the different memories in the Atmel
ture has two main memory spaces, the Data Memory and the Program Memory space. In
addition, the ATmega32 features an EEPROM Memory for data storage. All three memory
spaces are linear and regular.
The ATmega32 contains 32 Kbytes On-chip In-System Reprogrammable Flash memory for pro-
gram storage. Since all AVR instructions are 16 or 32 bits wide, the Flash is organized as 16K ×
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 ATmega32 Pro-
gram Counter (PC) is 14 bits wide, thus addressing the 16K program memory locations. The
operation of Boot Program section and associated Boot Lock bits for software protection are
described in detail in
