Overview
In-System Reprogrammable Flash Program Memory
This section describes the different memories in the ATmega48A/PA/88A/PA/168A/PA/328/P.
The AVR architecture has two main memory spaces, the Data Memory and the Program Mem-
ory space. In addition, the ATmega48A/PA/88A/PA/168A/PA/328/P features an EEPROM
Memory for data storage. All three memory spaces are linear and regular.
The ATmega48A/PA/88A/PA/168A/PA/328/P contains 4/8/16/32Kbytes 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 2/4/8/16K x 16. For software security, the Flash Program
memory space is divided into two sections, Boot Loader Section and Application Program Sec-
tion in ATmega88PA and ATmega168PA. See SELFPRGEN description in section
Store Program Memory Control and Status Register” on page 295
The Flash memory has an endurance of at least 10,000 write/erase cycles. The
ATmega48A/PA/88A/PA/168A/PA/328/P Program Counter (PC) is 11/12/13/14 bits wide, thus
addressing the 2/4/8/16K program memory locations. The operation of Boot Program section
and associated Boot Lock bits for software protection are described in detail in
ming the Flash, ATmega 48A/48PA” on page 271
Self-Programming” on page
description on Flash Programming in SPI- or Parallel Programming mode.
Constant tables can be allocated within the entire program memory address space (see the LPM
– Load Program Memory instruction description).
