Overview
In-System Reprogrammable Flash Program Memory
This section describes the different memories in the ATmega1284P. The AVR architecture has
two main memory spaces, the Data Memory and the Program Memory space. In addition, the
ATmega1284P features an EEPROM Memory for data storage. All three memory spaces are lin-
ear and regular.
The ATmega1284P contains 128K 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
64 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 ATmega1284P
Program Counter (PC) is 16 bits wide, thus addressing the 64K program memory locations. The
operation of Boot Program section and associated Boot Lock bits for software protection are
described in detail in
291
JTAG interface.
Constant tables can be allocated within the entire program memory address space (see the LPM
– Load Program Memory instruction description.
