3V Power Supply 48-lead LQFP Package Description The Atmel AT43USB353M is an 8-bit microcontroller based on the AVR RISC architecture.
By executing powerful instructions in a single clock cycle, the AT43USB353M achieves throughputs approaching 24 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 AT43USB353M features an on-chip 24-Kbyte of masked ROM program memory and 1-Kbyte of data memory.
It is supported by a standard set of peripherals such as www.
DataSheet4U.
com timer/counter modules, watchdog timer and internal and external interrupt sources.
The major peripheral included in the AT43USB353M 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.
The AT43USB353M is binary compatible with the AT43USB355.
Program development and debugging for the AT43USB353M uses the AT43DK355, including all its tools and libraries.
