Microchip ATMEGA64A-AU ATMEGA64A-AU 8 Bit MCU Low Power High Performance AVR Atmega Family ATmega64 Series Microcontrollers

The ATMEGA64A-AU is a 8-bit high-performance low-power AVR RISC-based Microcontroller combines 64kB ISP flash memory with read-while-write capabilities, 2kB EEPROM, 4kB SRAM, 53 general purpose I/O lines, 32 general purpose working registers, a real time counter, four flexible timer/counters with compare modes and PWM, two USARTs, a byte-oriented 2-wire serial interface, an 8-channel/10-bit A/D converter with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, SPI serial port, a JTAG (IEEE 1149.1 compliant) test interface for on-chip debugging and programming and six software selectable power saving modes. The device operates between 2.7 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.

• Advanced RISC architecture - On-chip 2-cycle multiplier
• High endurance, non-volatile memory segments
• JTAG (IEEE 1149.1 compliant) interface
• QTouch® library support - Capacitive touch buttons, sliders and wheels
• Peripheral features - Real time counter with separate oscillator
• Power-on reset (POR) and programmable brown-out detection
• Internal calibrated RC oscillator
• External and internal interrupt sources
• Six sleep modes - Idle, ADC noise reduction, power-save, power-down, standby and extended standby
• Software selectable clock frequency
• ATmega103 compatibility mode selected by a fuse
• Global pull-up disable
