This section describes the different memories in the ATmega162. The AVR architecture has two
main memory spaces, the Data Memory and the Program Memory space. In addition, the
ATmega162 features an EEPROM Memory for data storage. All three memory spaces are linear
and regular.
The ATmega162 contains 16K bytes 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 ATmega162
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
“Memory Programming” on page 231
loading using the SPI pins or the JTAG interface.
Constant tables can be allocated within the entire program memory address space (see the LPM
– Load Program Memory instruction description).
