Description  
The Atmel AT43USB326 is an 8-bit microcontroller based on the AVR RISC architec-  
ture. By executing powerful instructions in a single clock cycle, the AT43USB326  
achieves throughputs approaching 12 MIPS. The AVR core combines a rich instruc-  
tion set with 32 general-purpose working registers. All 32 registers are directly  
connected to the ALU allowing two independent registers to be accessed in one single  
instruction executed in one clock cycle. The resulting architecture is more code effi-  
cient while achieving throughputs up to ten times faster than conventional CISC  
microcontrollers.  
AT43USB326  
Furthermore, the AT43USB326 features an on-chip 16-Kbyte program memory and  
512 bytes of data memory. It is supported by a standard set of peripherals such as  
timer/counter modules, watchdog timer and internal and external interrupt sources.  
The major peripheral included in the AT43USB326 is the USB Hub with an embedded  
keyboard controller function.
