Product Overview: ATMEGA328P-20MU from Microchip Technology

The ATMEGA328P-20MU is a high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller. Combining 32KB ISP flash memory, 1KB EEPROM, 2KB SRAM, 23 general-purpose I/O lines, 32 general-purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter (8 channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The device operates between 1.8-5.5 volts.

By executing powerful instructions in a single clock cycle, the ATMEGA328P-20MU achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed. This microcontroller is the engine behind the popular Arduino Uno board, making it a favorite among hobbyists and professionals for rapid prototyping and production in embedded systems.
