Atmel AVR AT90USB64/128 memories
This section describes the different memories in the AT90USB64/128. The AVR architecture has
two main memory spaces, the Data Memory and the Program Memory space. In addition, the
AT90USB64/128 features an EEPROM Memory for data storage. All three memory spaces are
linear and regular.
Notes:
1. Byte address.
2. Word (16-bit) address.
6.1
In-system re-programmable flash program memory
The AT90USB64/128 contains 128Kbytes On-chip In-System Re-programmable Flash memory
for program storage. Since all AVR instructions are 16 or 32 bits wide, the Flash is organized as
64K × 16. For software security, the Flash Program memory space is divided into two sections,
Boot Program section and Application Program section.
The Flash memory has an endurance of at least 100,000 write/erase cycles. The
AT90USB64/128 Program Counter (PC) is 16 bits wide, thus addressing the 128K program
memory locations. The operation of Boot Program section and associated Boot Lock bits for
