ATmega64A, 8-Bit Microcontroller, TQFP-64

The ATmega64A is a low-power CMOS 8-bit microcontroller from Microchip Technology, based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega64A achieves throughputs approaching 1 MIPS per MHz, allowing system designers to optimize power consumption versus processing speed.

This microcontroller features 64KB of In-System Self-Programmable Flash memory, enabling firmware updates without external programming devices. It also includes 4KB of SRAM and 2KB of EEPROM, providing ample data storage for a variety of applications.

With 53 programmable I/O lines, the ATmega64A offers extensive interfacing capabilities. Its advanced peripherals include two 8-bit Timer/Counters, two expanded 16-bit Timer/Counters, a Real-Time Counter with a separate oscillator, dual programmable serial USARTs, a byte-oriented Two-Wire Serial Interface, an 8-channel 10-bit ADC, and a programmable Watchdog Timer with an internal oscillator.

The integrated JTAG interface supports on-chip debugging and programming, as well as boundary-scan capabilities according to the JTAG standard. The device operates over a voltage range of 2.7V to 5.5V and can run at speeds up to 16 MHz, making it suitable for a wide range of applications, including industrial automation, consumer electronics, and embedded systems.
