1 / 115 page  1 Features • AVR® 8-bit RISC Microcontroller with 83 ns Instruction Cycle Time • USB Hub with One Attached and Two External Ports • USB Function with Three Programmable End-points • 24 KB Program Memory, 1 KB Data SRAM • 32 x 8 General-purpose Working Registers • 27 Programmable I/O Port Pins • 12-channel 10-bit ADC • Master/Slave SPI Serial Interface • One 8-bit Timer/Counter with Separate Pre-scaler • One 16-bit Timer/Counter with Separate Pre-scaler and Two PWMs • External and Internal Interrupt Sources • Programmable Watchdog Timer • 6 MHz Oscillator with On-chip PLL • 5V Operation with On-chip 3.3V Power Supply • 64-lead LQFP Package Description The Atmel AT43USB355 is an 8-bit microcontroller based on the AVR RISC architec- ture. By executing powerful instructions in a single clock cycle, the AT43USB355 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. Furthermore, the AT43USB355 features an on-chip 24-Kbyte program memory and 1-Kbyte 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 AT43USB355 is a full-speed USB 2.0 Hub with an embedded function and a 12-channel Analog-to-Digital Converter (ADC) for use in applications such as game controllers.
