In-System Reprogrammable Flash Program Memory
Atmel ATmega16/32/64/M1/C1
This section describes the different memories in the ATmega16/32/64/M1/C1. The AVR archi-
tecture has two main memory spaces, the Data Memory and the Program Memory space. In
addition, the ATmega16/32/64/M1/C1 features an EEPROM Memory for data storage. All
three memory spaces are linear and regular.
The ATmega16/32/64/M1/C1 contains 16K/32K/64K bytes On-chip In-System Reprogramma-
ble Flash memory for program storage. Since all AVR instructions are 16 or 32 bits wide, the
Flash is organized as 8K x 16, 16K x 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 Flash memory has an endurance of at least 10,000 write/erase cycles. The
ATmega16/32/64/M1/C1 Program Counter (PC) is 14/15 bits wide, thus addressing the
8K/16K/32K program memory locations. The operation of Boot Program section and associ-
ated Boot Lock bits for software protection are described in detail in
Read-While-Write Self-Programming ATmega16/32/64/M1/C1” on page

Parallel programming mode.
Constant tables can be allocated within the entire program memory address space (see the
LPM – Load Program Memory.
