Microchip Technology ATMEGA328P-PN Microcontroller
The ATMEGA328P-PN is a high-performance, low-power Microchip picoPower 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 six-channel 10-bit A/D converter (eight 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-PN achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed. Designed for more demanding applications, it offers substantial program and data memories with performance up to 20 MIPS. With its complete feature set and extensive I/O capabilities, this microcontroller is ideal for applications requiring a high level of control and connectivity, such as industrial automation, home automation, and IoT devices.
The microcontroller's versatility is further enhanced by the In-System Programming feature, which allows for firmware upgrades without removing the microcontroller from its application. Additionally, it supports In-Circuit Debugging/Programming with on-chip debug capability.
The ATMEGA328P-PN is compatible with the Arduino development platform, which makes it a popular choice for hobbyists and educators, as well as professional engineers developing prototypes. Its robustness, extensive support, and ease of use have made it a go-to microcontroller for a wide range of projects.
With its rich set of peripherals and low power consumption, the ATMEGA328P-PN from Microchip Technology is a reliable and economical choice for sophisticated and power-sensitive applications in embedded systems.
