Memories
6.1
Overview
The main memories are SRAM data memory, EEPROM data memory, and Flash program memory. In
addition, the peripheral registers are located in the I/O memory space.

In-System Reprogrammable Flash Program Memory
The ATtiny417/817 contains 4/8KB On-Chip In-System Reprogrammable Flash memory for program
storage. Since all AVR instructions are 16 or 32 bits wide, the Flash is organized as 4K x 16. For write
protection, the Flash Program memory space can be divided into three sections: Boot Loader section,
Application code section and Application data section, with restricted access rights among them.
The program counter is 11/12 bits wide to address the whole program memory. The procedure for writing
Flash memory is described in detail in the documentation of the Non-Volatile Memory Controller
(NVMCTRL) peripheral.
