In-System Re-programmable Flash Program Memory
This section describes the different memories in the ATtiny87/167. The AVR architecture has
two main memory spaces, the Data memory and the Program memory space. In addition, the
ATtiny87/167 features an EEPROM Memory for data storage. All three memory spaces are
linear and regular.
Table 3-1.
Notes:
The ATtiny87/167 contains On-chip In-System Reprogrammable Flash memory for program
storage (see “Flash size” in
wide, the Flash is organized as 16 bits wide. ATtiny87/167 does not have separate Boot
Loader and Application Program sections, and the SPM instruction can be executed from the
entire Flash. See SELFPRGEN description in
and Status Register – SPMCSR” on page 219
The Flash memory has an endurance of at least 10,000 write/erase cycles in automotive
range. The ATtiny87/167 Program Counter (PC) address the program memory locations.
