In-System Reprogrammable Flash Program Memory
SRAM Data Memory
AT90PWM216/316
This section describes the different memories in the AT90PWM216/316. The AVR architecture
has two main memory spaces, the Data Memory and the Program Memory space. In addition,
the AT90PWM216/316 features an EEPROM Memory for data storage. All three memory
spaces are linear and regular.
The AT90PWM216/316 contains 16K bytes 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
8K x 16. For software security, the Flash Program memory space is divided into two sections,
Boot Program section and Application Program section.
The Flash memory has an endurance of at least 10,000 write/erase cycles. The
AT90PWM216/316 Program Counter (PC) is 13 bits wide, thus addressing the 16K program
memory locations. The operation of Boot Program section and associated Boot Lock bits for
software protection are described in detail in
gramming” on page
on Flash programming in SPI or Parallel programming mode.
Constant tables can be allocated within the entire program memory address space (see the LPM
– Load Program Memory.
Timing diagrams for instruction fetch and execution are presented in

Figure 6-1.
