Overview
In-System Reprogrammable Flash Program Memory
This section describes the different memories in the ATmega48P/88P/168P. The AVR architec-
ture has two main memory spaces, the Data Memory and the Program Memory space. In
addition, the ATmega48P/88P/168P features an EEPROM Memory for data storage. All three
memory spaces are linear and regular.
The ATmega48P/88P/168P contains 4/8/16 bytes On-chip In-System Reprogrammable Flash
memory for program storage. Since all AVR instructions are 16 or 32 bits wide, the Flash is orga-
nized as 2/4/8 x 16. For software security, the Flash Program memory space is divided into two
sections, Boot Loader Section and Application Program Section in ATmega88P and
ATmega168P. ATmega48P does not have separate Boot Loader and Application Program sec-
tions, and the SPM instruction can be executed from the entire Flash. See SELFPRGEN
description in section
273
The Flash memory has an endurance of at least 10,000 write/erase cycles. The
ATmega48P/88P/168P Program Counter (PC) is 11/12/13 bits wide, thus addressing the 2/4/8
program memory locations. The operation of Boot Program section and associated Boot Lock
bits for software protection are described in detail in
on page 267
and ATmega168P” 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).
Timing diagrams for instruction fetch and execution are presented in
