AT43USB320A-AC

AT43USB320A-AC Datasheet

The Atmel AT43USB320A is an 8-bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle, the AT43USB320A achieves throughputs approaching 12 MIPS. The AVR core combines a rich instruction 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 efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.

The AT43USB320A features an on-chip 512-byte 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 AT43USB320A is the USB Hub with an embedded function for use in peripherals such as monitor with remote control as shown in Figure Note: There are two versions of the AT43USB320A. They are indicated by the internal part numbers 55618D and 55618E. The only difference between the two versions is in the polarity of the SUSPEND pin. The 55618D SUSPEND pin is active low, while the 55618E SUSPEND pin is active high.
