Overview
In-System Reprogrammable Flash Program Memory
SRAM Data Memory
This section describes the different memories in the ATmega16HVB/32HVB. The AVR architec-
ture has two main memory spaces, the Data Memory and the Program Memory space. In
addition, the ATmega16HVB/32HVB features an EEPROM Memory for data storage. All three
memory spaces are linear and regular.
The ATmega16HVB/32HVB contains 16K/32K 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 8K/16K x 16.
The Flash memory has an endurance of at least 10,000 write/erase cycles. The
ATmega16HVB/32HVB Program Counter (PC) is 13/14 bits wide, thus addressing the 8K/16K
program memory locations. The operation of Boot Program section and associated Boot Lock
bits for software protection are described in detail in
Self-Programming” on page
description on Flash programming.
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
