ATMEGA2561-16AUR 詳細描述
Product Overview
The ATMEGA2561-16AUR is an 8-bit Microchip Technology microcontroller from the AVR® ATmega family. It provides 256KB (128K x 16) of FLASH program memory, 8K x 8 RAM, and 4K x 8 EEPROM. The device operates at 16MHz with an internal oscillator and supports a 4.5V to 5.5V supply range. It is offered in a 64-TQFP (14x14) surface-mount package and provides 54 I/O pins for digital control, interfacing, and peripheral expansion.
Key Features
- 8-bit AVR core with 16MHz operating speed.
- 256KB (128K x 16) FLASH program memory, 8K x 8 RAM, and 4K x 8 EEPROM.
- 54 I/O pins for digital control and peripheral interfacing.
- Connectivity options include EBI/EMI, I2C, SPI, and UART/USART.
- Integrated peripherals include PWM, brown-out detect/reset, power-on reset, and watchdog timer.
- Eight 10-bit analog-to-digital converter channels are available.
- Internal oscillator and 4.5V to 5.5V supply range support system-level integration.
- 64-TQFP (14x14) surface-mount package for board-level embedded designs.
Applications
- Embedded control systems using 54 I/O pins and FLASH program memory.
- Sensor measurement designs using eight 10-bit ADC channels.
- Peripheral and communication interfaces using EBI/EMI, I2C, SPI, and UART/USART.
- Timing and protection functions using PWM, watchdog timer, brown-out detect/reset, and power-on reset.
Design & Procurement Notes
For PCB planning, note the 64-TQFP (14x14) surface-mount package and 54 I/O pins, which affect routing density and connector or header allocation. The 4.5V to 5.5V supply range should be matched to the board power architecture. The internal oscillator, 16MHz speed, FLASH program memory, EEPROM, RAM, ADC channels, PWM, and communication interfaces define the resources available for firmware and hardware partitioning. The -40°C to 85°C operating temperature range should be considered when placing the device near heat-generating components or in enclosures with limited airflow.
