ATMEGA1280-16AU 詳細描述
Product Overview
The ATMEGA1280-16AU from Microchip Technology is an 8-bit AVR microcontroller for embedded control designs that require multiple digital I/O paths, serial communication interfaces, and on-chip analog measurement. It provides 128KB (64K x 16) FLASH program memory, 8K x 8 RAM, and 4K x 8 EEPROM, with a 16MHz speed rating and an internal oscillator. The device uses a 100-TQFP (14x14) surface-mount package and operates from a 2.7V to 5.5V supply over a temperature range of -40°C to 85°C.
Key Features
- 8-bit AVR core with 16MHz speed and internal oscillator.
- 128KB (64K x 16) FLASH program memory, 8K x 8 RAM, and 4K x 8 EEPROM.
- 86 I/O pins for digital control, sensing, and peripheral interfacing.
- EBI/EMI, I2C, SPI, and UART/USART connectivity.
- 16-channel 10-bit ADC, PWM, brown-out detect/reset, POR, and WDT.
Applications
- Embedded control boards using many digital inputs and outputs for switches, indicators, or discrete control signals.
- Sensor measurement modules sampling multiple analog signals through the 16-channel 10-bit ADC.
- Peripheral interface units connecting to I2C, SPI, UART/USART, or EBI/EMI devices.
- PWM-driven output stages for timing-based actuation or modulation.
Design & Procurement Notes
Design teams should verify the 100-TQFP (14x14) surface-mount footprint, pinout, and PCB routing before layout, because the 86 I/O and multiple communication interfaces require careful signal placement. The 2.7V to 5.5V supply range and -40°C to 85°C operating temperature range should be checked against the final power and environmental conditions. The 128KB FLASH, 8K x 8 RAM, and 4K x 8 EEPROM provide fixed on-chip memory resources, so firmware size and data storage needs should be mapped to these capacities. The device has an internal oscillator and a 16MHz speed rating, while external timing requirements, analog input layout, and brown-out, POR, and watchdog behavior should be reviewed during system integration.
