ATMEGA328P-ANR Description

Short technical summary and product information.

The ATMEGA328P-ANR 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 SRAM, and 1KB of EEPROM. The device operates at a maximum speed of 20MHz and supports a wide supply voltage range of 1.8V to 5.5V.

 

Peripherals include two 8-bit and one 16-bit timer/counters, six PWM channels, an 8-channel 10-bit ADC, and an on-chip analog comparator. Connectivity options include I²C, SPI, and UART/USART interfaces. The microcontroller also features brown-out detection, power-on reset, and a programmable watchdog timer.

 

The ATMEGA328P-ANR is housed in a 32-lead TQFP package (7x7mm) with surface-mount gull-wing leads. It is suitable for a variety of embedded applications including consumer electronics, industrial control, automotive systems, medical devices, and IoT endpoints. The device is RoHS3 compliant and REACH unaffected.
