Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ATMEGA328P-AU is an 8-bit megaAVR microcontroller based on the AVR enhanced RISC architecture. It integrates 32KB of in-system self-programming Flash program memory, 1KB of EEPROM and 2KB of SRAM, providing rich storage resources to meet various application requirements. The microcontroller features 23 general-purpose I/O lines, 32 general-purpose operating registers and a wide range of peripheral functions, including two 8-bit timer/counters, a 16-bit timer/counter, a 6-channel 10-bit analogue-to-digital converter (ADC), a programmable serial USART, a master/slave SPI serial interface, and a 2-wire byte-oriented serial interface (I2C compatible). The ATMEGA328P-AU also supports a variety of low-power modes, allowing it to excel in battery-powered applications.

Product Features

High performance and low power consumption: With a maximum operating frequency of 20MHz, the ATMEGA328P-AU is capable of achieving up to 20MIPS throughput, and features picoPower technology, which provides ultra-low power consumption and multiple power-saving sleep modes, making it ideal for battery-powered applications.

Rich storage resources: 32KB Flash programme memory, 1KB EEPROM and 2KB SRAM provide ample space for programme and data storage.

Flexible I/O and peripherals: 23 general-purpose I/O lines support a wide range of peripheral functions, including timer, ADC, USART, SPI and I2C interfaces to meet the interface requirements of different applications.

Multiple low-power modes: Supports six power-saving sleep modes, including idle, ADC noise reduction, power-saving, power-down, standby and long-time standby modes, helping to reduce system power consumption.

Reliability and Security: Highly durable non-volatile memory segments with write/erase cycles up to 10,000 (Flash) and 100,000 (EEPROM), and data retention time of up to 20 years (85°C) and 100 years (25°C) ensure long-term data reliability.

Wide operating voltage range: Supports an operating voltage range of 1.8V to 5.5V, adapting to different power supply environments.

Strong temperature adaptability: Operating temperature range from -40°C to +85°C, capable of stable operation in various harsh environments.

Variety of packages: TQFP-32 package, size 7.1mm x 7.1mm x 1.05mm, suitable for surface mount installation.
