ATMEGA644A-MU  

Microcontrollers

The ATMEGA644A-MU is a microcontroller unit (MCU) produced by Microchip Technology. It is part of the AVR Enhanced series of MCUs and is based on the ATmega644A microcontroller.

Description:

The ATMEGA644A-MU is a low-power, high-performance 8-bit microcontroller with 64KB of in-system programmable flash memory. It features a rich set of communication interfaces, including a universal serial interface (USI), two USARTs, and a two-wire interface. The MCU also includes a range of peripherals, such as an 8-channel 10-bit analog-to-digital converter (ADC), a real-time counter (RTC), and a watchdog timer (WDT).

Features:

• 64KB of in-system programmable flash memory
• 8KB of SRAM
• 2KB of EEPROM
• 8-channel, 10-bit ADC
• Two USARTs with mode support for SPI, I2C, and TWI
• Universal Serial Interface (USI)
• Real-time counter (RTC)
• Watchdog timer (WDT)
• Eight general-purpose I/O lines
• Three 16-bit timer/counters with PWM and phase-correct PWM modes
• On-chip debug system with JTAG interface
• Brown-out detection and reset
• Sleep mode to reduce power consumption

Applications:

The ATMEGA644A-MU is suitable for a wide range of applications, including:

1. Industrial control systems
2. Home automation and smart home devices
3. Medical devices and equipment
4. Portable electronics and wearable devices
5. Automotive systems and control modules
6. IoT devices and applications
7. Robotics and automation systems
