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 8bit 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
- Serial peripheral interface (SPI)
Footnotes New IC marking code is implemented, instead ATMEGA328 -PU used ATMEGA328 -U. Warnings Market demand for this product has caused an extension in leadtimes. Delivery dates may fluctuate. Product exempt from discounts.
