ATMEGA328P-MUR Description

Short technical summary and product information.

The ATMEGA328P-MUR is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features 32KB of in-system self-programmable Flash memory, 2KB of internal SRAM, and 1KB of EEPROM with high endurance (10,000 write/erase cycles for Flash and 100,000 for EEPROM). The device operates at a maximum clock frequency of 20MHz, delivering up to 20 MIPS throughput.

 

This microcontroller includes a rich set of peripherals: two 8-bit timers, one 16-bit timer, six PWM channels, an 8-channel 10-bit ADC, and serial communication interfaces including I²C, SPI, and USART. It also features a brown-out detect/reset, power-on reset, and a watchdog timer. The operating voltage range is 1.8V to 5.5V, and the device is rated for an industrial temperature range of -40°C to +85°C.

 

The ATMEGA328P-MUR is supplied in a 32-VQFN (5x5mm) surface-mount package with an exposed pad for improved thermal performance. It is designed for a wide range of embedded control applications requiring low power consumption and high performance.
