The ATMEGA328-PU is an 8-bit microcontroller based on the AVR-enhanced RISC architecture. It executes powerful instructions in a single clock cycle, achieving a high throughput of up to 20MIPS at 20MHz. The microcontroller features 32 x 8 general-purpose working registers, fully static operation, and an on-chip 2-cycle multiplier. It offers flash memory with 10,000 write/erase cycles, EEPROM with 100,000 cycles, and an optional boot code section with independent lock bits. Key peripherals include timers/counters, PWM channels, USART, SPI, 2-wire serial interface, watchdog timer, analog comparator, and interrupt capabilities. The ATMEGA328-PU is suitable for applications requiring low-power operation and high performance.
