Overview
In-System Reprogrammable Flash Program Memory
ATmega4HVD/8HVD
This section describes the different memories in the ATmega4HVD/8HVD. The AVR architec-
ture has two main memory spaces, the Data Memory and the Program Memory space. In
addition, the ATmega4HVD/8HVD features an EEPROM Memory for data storage. All three
memory spaces are linear and regular.
The ATmega4HVD/8HVD contains 4/8K 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 2K/4K x 16.
The Flash memory has an endurance of at least 10,000 write/erase cycles. The
ATmega4HVD/8HVD Program Counter (PC) is 11/12 bits wide, thus addressing the 2K/4K
program memory locations.

Constant tables can be allocated within the entire program memory address space (see the
LPM – Load Program Memory instruction description).
