AVR Memories

Overview
This section describes the different memories in the ATmega164P/324P/644P. The AVR archi-
tecture has two main memory spaces, the Data Memory and the Program Memory space. In
addition, the ATmega164P/324P/644P features an EEPROM Memory for data storage. All three
memory spaces are linear and regular.
6.2
In-System Reprogrammable Flash Program Memory
The ATmega164P/324P/644P contains 16/32/64K 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 32/64 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
ATmega164P/324P/644P Program Counter (PC) is 15/16 bits wide, thus addressing the 32/64K
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 296.
“Memory Programming” on page 296 contains a detailed description on Flash data serial down-
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.
Timing diagrams for instruction fetch and execution are presented in “Instruction Execution Tim-
