Why Does the AVR Win theBenchmarks?

Code size– Architecture tuned for C– 32 working registers– Efficient 16/32-bit data support– Large and linear address spaces(8 mbyte)– Efficient bit manipulation

Speed/performance– Single clock cycle instructions– No clock division from XTAL to CPU– Powerful instruction set– Efficient 16/32-bit data support

AVR Self Programming

• The ultimate In-System Re-programming solution• The AVR CPU writes directly to the Flash

– No external components

• In-System Re-program using UART, SPI, I2C, or customprotocols

• Perfect solution for “by-the-wire” remote upgrading– 1. Transfer the data over a ‘network’ to the system– 2. AVR receives data, writes to Flash, and upgrades itself !





Benefits with AVR Self ProgrammingiNo external components save costiFast programming time save production costiFull flexibility on programming schemes gives

the customer all choices on:– Speed, security and robustness

iTrue remote upgrading using existinginfrastructure for communication

Unique Features with AVR Self Programming

• Flexible Boot Block Sizes (128B - 2 KB)

• Smallest sector sizes, allows efficient data variablesmodifications–sector size is 128 Bytes

• Extremely fast programming time–10 ms for One Sector (128 Bytes)–16K (full Flash) in 1.3 sec.

• Program over the full temperature and voltageranges backback



Power Consumption

• Active Default mode. Entered after Reset or Wake-up.

•Idle Entered after a SLEEP execution with SE bit in MCUCR register.

•Power-Down Entered after SLEEP execution with SM bit set in MCUCR register.

•Power-Save* Entered after a SLEEP execution with SM0 and SM1 bit set.
