ATtiny2313
This section describes the different memories in the ATtiny2313. The AVR architecture has two
main memory spaces, the Data Memory and the Program Memory space. In addition, the
ATtiny2313 features an EEPROM Memory for data storage. All three memory spaces are linear
and regular.
The ATtiny2313 contains 2K bytes On-chip In-System Reprogrammable Flash memory for pro-
gram storage. Since all AVR instructions are 16 or 32 bits wide, the Flash is organized as 1K x
16.
The Flash memory has an endurance of at least 10,000 write/erase cycles. The ATtiny2313 Pro-
gram Counter (PC) is 10 bits wide, thus addressing the 1K program memory locations.
