Detailed Description for ATMEGA1280-16AUR
Product Overview
The ATMEGA1280-16AUR from Microchip Technology is an 8-bit AVR microcontroller intended for embedded control tasks. It provides 128KB (64K x 16) of FLASH program memory, 8K x 8 RAM, and 4K x 8 EEPROM, with a specified speed of 16MHz and an internal oscillator. The device supports 86 I/O points and includes interfaces such as EBI/EMI, I2C, SPI, and UART/USART. It uses a 100-TQFP (14x14) surface-mount package and operates over a -40°C to 85°C ambient temperature range.
Key Features
- 8-bit AVR core with a specified speed of 16MHz.
- 128KB (64K x 16) FLASH program memory, 8K x 8 RAM, and 4K x 8 EEPROM.
- 86 I/O points for expanded peripheral and control connections.
- Communication interfaces include EBI/EMI, I2C, SPI, and UART/USART.
- On-chip peripherals include PWM, brown-out detect/reset, POR, and WDT.
- 16 analog-to-digital inputs with 10-bit resolution.
- Internal oscillator for timing generation.
- 100-TQFP (14x14) surface-mount package with 2.7V to 5.5V supply range and -40°C to 85°C ambient operating temperature.
Applications
- Embedded control systems requiring multiple digital I/O and serial communication links.
- Data acquisition assemblies that use 10-bit analog inputs to monitor sensors.
- Motor or actuator control subsystems using PWM outputs.
- Instrumentation or equipment controllers that combine FLASH program storage, EEPROM parameter retention, and RAM working storage.
Design & Procurement Notes
Design considerations should center on the fixed 100-TQFP footprint, the 86 I/O allocation, and the 2.7V to 5.5V supply range. The 16MHz specified speed, internal oscillator, and 128KB FLASH memory set the timing and program capacity envelope, while 8K x 8 RAM and 4K x 8 EEPROM define runtime and EEPROM storage budgets. The presence of EBI/EMI, I2C, SPI, and UART/USART supports multi-interface system architectures, and the 16x10-bit A/D function supports analog measurement paths. The -40°C to 85°C ambient range should be evaluated against the final enclosure thermal environment. For procurement, specify the exact part number ATMEGA1280-16AUR to match the 100-TQFP package and the 16MHz, 128KB FLASH, 86 I/O configuration.
