ATMEGA328-PU Datasheet PDF - ATMEL

●The ATMEGA328-PU is a low power CMOS 8 bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA328-PU achieves throughputs approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

● 131 powerful instructions - Most Single Clock Cycle Execution

● 32 x 8 general purpose working registers

● Fully static operation

● Up to 20MIPS throughput at 20MHz

● On-chip 2-cycle multiplier

● Write/erase cycles: 10,000 flash/100,000 EEPROM

● Optional boot code section with independent lock bits

● In system programming by on chip boot program

● True read while write operation

● Programming lock for software security

● Atmel® QTouch® library support

● Capacitive touch buttons, sliders and wheels

● QTouch and QMatrix® acquisition

● Up to 64 sense channels

● Two 8-bit timer/counters with separate prescaler and compare mode

● One 16-bit timer/counter with separate prescaler, compare mode, and capture mode

● Real time counter with separate oscillator

● Six PWM channels

● Programmable serial USART

● Master/Slave SPI
