Program Memory (Flash)
The AVR architecture makes a distinction between program memory and data memory, locating
each memory type in a separate address space. Executable code is located in non-volatile pro-
gram memory (Flash), whereas data can be placed in either volatile (SRAM) or non-volatile
memory (EEPROM). See
Figure 5-1.
All memory spaces are linear and regular.
ATtiny48/88 contains 4/8K byte of on-chip, in-system reprogrammable Flash memory for pro-
gram storage. Flash memories are non-volatile, i.e. they retain stored information even when not
powered.
Since all AVR instructions are 16 or 32 bits wide, the Flash is organized as 4096/8192 x 16 bits.
The Program Counter (PC) is 11/12 bits wide, thus capable of addressing all 4096/8192 loca-
tions of program memory, as illustrated in
Table 5-1.
Constant tables can be allocated within the entire address space of program memory. See
instructions LPM (Load Program Memory), and SPM (Store Program Memory) in
