![]() ![]() This product line contains multiple 8-bit microcontrollers of different shapes, pin configurations, and sizes. The ATmega328P is part of the ATmega328 product line. ![]() The memory is divided into two sections: a boot loader and an application program section. Since the flash memory is so flexible, security is a foremost concern. Designers can rely on the flash memory to handle at least 10,000 write/erase cycles. This memory can be reprogrammed through multiple interfaces on the chip, and the flash memory does not interfere with execution in the general purpose registers. The chip’s memory and its execution registers are both programmable, and the ATmega328P includes 32KB of onboard flash memory. For programming ease, the datasheet also translates its assembly language samples into C code. The datasheet includes many code samples in assembly language. Its versatility makes it ideal for jobs consumers rely on, such as control within automobiles.Ī key feature of the ATmega328P is that programmers can customize its functionality through targeted programming of its registers. This processing power is reliable throughout a wide temperature range, from -40 to 125 degrees Celsius. ![]() Using a reduced instruction set computer (RISC) architecture, the ATmega328P can process instructions up to 10 times faster than other comparable microcontrollers. The ATmega328P connects all its general purpose registers to its arithmetic logic unit (ALU), which allows instructions in two different registers to be executed at the same time. 131 unique instructions are possible within the chip’s registers, and combinations of those instructions allow for high variability and fast execution. This is possible because the chip is optimized for maximum efficiency and minimum power usage. The ATmega328P datasheet describes the component as capable of handling complex instructions within a single clock cycle. All of its features are itemized in its datasheet. Designed for very high processing speeds, the ATmega328P includes many special features to optimize power usage and processing efficiency. It is a common component in Arduino robotics, and is often praised for its high performance with low power consumption. The ATmega328P is an 8-bit AVR microcontroller chip developed by Atmel (which was acquired by Microchip Technology in 2016). Variants of the ATmega328P in the Ultra Librarian search engine. ![]()
