The ATMEGA328P-MNR is a high-performance, low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It integrates 32KB of in-system self-programmable Flash program memory, 1KB EEPROM, and 2KB internal SRAM. This device operates with a power supply range of 1.8V to 5.5V and can achieve throughputs approaching 20 MIPS at 20 MHz. Supplied in a 32-pad QFN package, this model is rated for the industrial temperature range of -40°C to 105°C, making it a flexible and cost-effective solution for various embedded control applications.
