AVR Memories

This section describes the different memories in the ATtiny13. The AVR architecture

has two main memory spaces, the Data memory and the Program memory space. In

addition, the ATtiny13 features an EEPROM Memory for data storage. All three memory

spaces are linear and regular.

In-System Re-

programmable Flash

Program Memory

The ATtiny13 contains 1K byte On-chip In-System Reprogrammable Flash memory for

program storage. Since all AVR instructions are 16 or 32 bits wide, the Flash is orga-

nized as 512 x 16.

The Flash memory has an endurance of at least 10,000 write/erase cycles. The

ATtiny13 Program Counter (PC) is nine bits wide, thus addressing the 512 Program

memory locations. “Memory Programming” on page 103 contains a detailed description

on Flash data serial downloading using the SPI pins.

Constant tables can be allocated within the entire Program memory address space (see

the LPM – Load Program memory instruction description).

Timing diagrams for instruction fetch and execution are presented in “Instruction Execu-

tion Timing” on page 10.
