MICROCHIP ATMEGA324A-AU 8 Bit MCU, Low Power High Performance, AVR ATmega Family ATmega324 Series Microcontrollers, AVR

The ATMEGA324A-AU is a 8-bit high-performance AVR RISC-based Microcontroller combines 32kB ISP flash memory with read-while-write capabilities, 1kB EEPROM, 2kB SRAM, 32 general purpose I/O lines, 32 general purpose working registers, a real time counter, three 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 1.8 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
• QTouch® library support - Capacitive touch buttons, sliders and wheels
• JTAG (IEEE 1149.1 compliant) interface
• Peripheral features - Real time counter with separate oscillator
• Power-on reset (POR) and programmable brown-out detection
• Internal calibrated oscillator
• External and internal interrupt sources
• Six sleep modes - Idle, ADC noise reduction, power-save, power-down, standby and extended standby
