ATMEGA324PA-MUR

ATmega324PA-MUR is an 8-bit AVR microcontroller from Microchip/Atmel (megaAVR family). It uses the AVR RISC core with most instructions in one cycle and runs up to about 20 MHz. Key specs (typical):
- Memory: 32 KB flash, 1 KB EEPROM, ~2 KB SRAM
- Peripherals: USART, SPI, I2C (TWI); two 8-bit timers plus one 16-bit timer; PWM outputs; 8-channel 10-bit ADC; analog comparator; multiple external interrupts
- I/O: a multi-pin digital I/O port set (package dependent)
- Power/clock: operates from 1.8–5.5 V
- Features: watchdog timer, brown‑out detector, several sleep modes; ISP programming
- Packaging: -MUR denotes a specific surface-mount package and temperature grade (check datasheet for pinout)
Uses: general-purpose embedded control, sensors, small automation, hobby boards. Development supported by AVR-GCC, Microchip Studio, and bootloaders (depending on board). For exact pinout, voltage range, and timing, refer to the datasheet.
