Description:

• This high-performance Microchip picoPower® 8-bit AVR® RISC-based microcontroller has the following features: a 6-channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages), a programmable watchdog timer with an internal oscillator, three flexible timer/counters with compare modes, internal and external interrupts, a serial programmable USART, a byte-oriented Two-Wire serial interface, an SPI serial port, a programmable watchdog timer with an internal oscillator, and five software-selectable power-saving modes.
• The device operates between 1.8 and 5.5 volts.
• By executing strong instructions in a single clock cycle, the device achieves throughputs of around one MIPS per MHz, balancing power consumption and processing performance.
• The ATMEGA328P-AU is a versatile, high-performance 8-bit AVR microcontroller designed by Microchip Technology, known for its frugal power consumption and processing capabilities.
