Product Overview: ATMEGA328P-MNR from Microchip Technology
The ATMEGA328P-MNR is a high-performance, low-power Microchip picoPower® 8-bit AVR® RISC-based microcontroller. This microcontroller combines 32KB ISP flash memory with read-while-write capabilities, 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 at a frequency of up to 20MHz with a voltage range of 1.8-5.5 volts. By executing powerful instructions in a single clock cycle, the ATMEGA328P-MNR achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
