The ATMEGA328-MUR is a high-performance, low-power Microchip picoPower® 8-bit AVR® RISC-based microcontroller. This versatile microcontroller combines 32KB ISP flash memory with read-while-write capabilities, 1KB EEPROM, 2KB SRAM, 23 general-purpose I/O lines, 32 general-purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, a serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter (8 channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes.
The device operates between 1.8-5.5 volts, making it suitable for a wide range of applications, including battery-powered devices and handheld equipment. By executing powerful instructions in a single clock cycle, the ATMEGA328-MUR achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
