AVR memories
This chapter describes the different memories in the Atmel
ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P. The AVR architecture has two main
m e m o ry spa c es, the Dat a M e m o r y an d t he Prog ra m M e m o r y sp ace . In ad dition , th e
ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P features an EEPROM Memory for
data storage. All three memory spaces are linear and regular.
8.1
In-System Reprogrammable Flash Program Memory
The ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P 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 8K x 16. For software security, the Flash Program memory space is divided into
two sections, Boot Program section and Application Program section.
The
Flas h
memory
has
an
en durance
of
at
least
10,000
write/erase
cycles.
The
ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P Program Counter (PC) is 13/14/15
bits wide, thus addressing the 8/16/32K 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-
Write Self-Programming” on page 241. ”Memory programming” on page 257 contains a detailed 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 timing” on page 14.

SRAM data memory
Figure 8-2 on page 19 shows how the SRAM Memory is organized.
The ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P is a complex microcontroller with
more peripheral units than can be supported within the 64 locations reserved in the Opcode for the IN and OUT
