ATMEGA64A-MUR

The Atmel ATMEGA64A-MUR is a high-performance, low-power 8-bit microcontroller based on the enhanced AVR RISC architecture. It executes powerful instructions in a single clock cycle, achieving throughputs close to 1 MIPS per MHz, allowing optimization for power consumption versus processing speed.

This microcontroller features 64KB of self-programmable Flash program memory, 2KB of EEPROM, and 4KB of internal SRAM. It operates at speeds up to 16MHz and supports a voltage range of 2.7V to 5.5V. Key peripherals include two 8-bit timer/counters, two expanded 16-bit timer/counters, an 8-channel 10-bit ADC, and dual programmable USARTs.

The ATMEGA64A-MUR is supplied in a 64-QFN (9x9) package suitable for surface mounting. It includes features like Power-on Reset, Programmable Brown-out Detection, and an internal calibrated RC oscillator. The device also supports various sleep modes for power efficiency and offers extensive on-chip debug support via its JTAG interface.

With 53 programmable I/O lines and connectivity options including I²C, SPI, and UART/USART, this microcontroller is well-suited for a wide range of embedded applications requiring efficient processing and peripheral integration.
