In-System Reprogrammable Flash Program Memory
AT90CAN32/64/128
This section describes the different memories in the AT90CAN32/64/128. The AVR architecture
has two main memory spaces, the Data Memory and the Program Memory space. In addition,
the AT90CAN32/64/128 features an EEPROM Memory for data storage. All three memory
spaces are linear and regular.
Table 4-1.
Notes:
The AT90CAN32/64/128 contains On-chip In-System Reprogrammable Flash memory for pro-
gram storage (see “Flash size”). Since all AVR instructions are 16 or 32 bits wide, the Flash is
organized as 16 bits wide. For software security, the Flash Program memory space is divided
into two sections, Boot Program section and Application Program section.
The Flas h memory has an endur ance of at leas t 10,000 write/eras e cyc les. T he
AT90CAN32/64/128 Program Counter (PC) address the program memory locations. The opera-
tion of Boot Program section and associated Boot Lock bits for software protection are described
in detail in
Programming” on page 335
using the SPI pins or the JTAG interface.
