AVR ATmega329/3290/649/6490 Memories
This section describes the different memories in the ATmega329/3290/649/6490. The Atmel
AVR architecture has two main memory spaces, the Data Memory and the Program Memory
space. In addition, the ATmega329/3290/649/6490 features an EEPROM Memory for data stor-
age. All three memory spaces are linear.

In-System Reprogrammable Flash Program Memory
The ATmega329/3290/649/6490 contains 32/64Kbytes 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 16/32K x 16. For software security, the Flash Program memory space is divided
into two sections, Boot Program section and Application Program section.
The F lash memory has an endurance of at least 10,000 write/erase cycles. The
ATmega329/3290/649/6490 Program Counter (PC) is 14/15 bits wide, thus addressing the
16/32K program memory locations. The operation of Boot Program section and associated Boot
Lock bits for software protection are described in detail in “Boot Loader Support – Read-While-
description on Flash data serial downloading 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).
Timing diagrams for instruction fetch and execution are presented in “Instruction Execution Tim-
Figure 7-1.
