AVR Memories
In-System Re-programmable Flash Program Memory
This section describes the different memories in the ATtiny167. The AVR architecture has two
main memory spaces, the Data memory and the Program memory space. In addition, the
ATtiny167 features an EEPROM Memory for data storage. All three memory spaces are linear
and regular.
Table 4-2.
The ATtiny167 contains On-chip In-System Reprogrammable Flash memory for program stor-
age (see “Flash size” in
the Flash is organized as 16 bits wide. ATtiny167 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
Register – SPMCSR” on page 244
The Flash memory has an endurance of at least 10,000 write/erase cycles in automotive range.
The ATtiny167 Program Counter (PC) address the program memory locations.
“Memory Programming” on page 250
loading using the SPI pins.
Constant tables can be allocated within the entire Program memory address space (see the
LPM – Load Program memory instruction description).
