Overview
In-System Reprogrammable Flash Program Memory
SRAM Data Memory
ATmega8HVA/16HVA
This section describes the different memories in the ATmega8HVA/16HVA. The AVR architec-
ture has two main memory spaces, the Data Memory and the Program Memory space. In
addition, the ATmega8HVA/16HVA features an EEPROM Memory for data storage. All three
memory spaces are linear and regular.
The ATmega8HVA/16HVA contains 8K/16K 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 4K/8K x 16.
The Flash memory has an endurance of at least 10,000 write/erase cycles. The
ATmega8HVA/16HVA Program Counter (PC) is 12/13 bits wide, thus addressing the 4K/8K pro-
gram memory locations.
Flash data serial programming.
Constant tables can be allocated within the entire program memory address space (see the LPM
– Load Program Memory instruction description).

The ATmega8HVA/16HVA is a complex microcontroller with more peripheral units than can be
supported within the 64 locations reserved in the Opcode for the IN and OUT instructions. For
