  • ATMEGA328P - AU Microcontroller  - (SMD Package) - TQFP - 32 Pin Microcontroller

The ATMEGA328P 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 ATMEGA328P achieves through puts approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. 

The high-performance Power 8-bit AVR RISC-based microcontroller combines 32KB ISP flash memory with read-while-write capabilities, 1024B 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 device achieves through puts approaching 1 MIPS per MHz, balancing power consumption and processing speed.
