Detailed Description for ATMEGA1280V-8AU
Product Overview
The Microchip Technology ATMEGA1280V-8AU is an AVR® ATmega 8-bit microcontroller IC in a 100-TQFP (14x14) surface-mount package. It provides 128KB (64K x 16) FLASH program memory, 8K x 8 RAM, and 4K x 8 EEPROM, with an internal oscillator and 8MHz speed. The device supports a 1.8V to 5.5V supply range and offers 86 I/O pins, along with EBI/EMI, I2C, SPI, and UART/USART connectivity.
Key Features
- AVR core processor with 8-bit architecture and 8MHz speed.
- 128KB (64K x 16) FLASH program memory, 8K x 8 RAM, and 4K x 8 EEPROM.
- 1.8V to 5.5V operating voltage range for Vcc/Vdd.
- 86 I/O pins in a 100-TQFP (14x14) surface-mount package.
- Supports EBI/EMI, I2C, SPI, and UART/USART interfaces.
- Includes Brown-out Detect/Reset, POR, PWM, and WDT peripherals.
- Provides 16x10b A/D data converters.
- Uses an internal oscillator and operates from -40°C to 85°C (TA).
Applications
- Embedded control tasks requiring multiple I/O pins and EBI/EMI, I2C, SPI, or UART/USART interfaces.
- Measurement or control systems that use 16x10b A/D conversion and PWM outputs.
- Systems requiring 128KB program FLASH, 8K x 8 RAM, and 4K x 8 EEPROM storage.
- Surface-mount designs operating from 1.8V to 5.5V in a 100-TQFP (14x14) package.
Design & Procurement Notes
Designers should confirm that the 8MHz speed, 1.8V to 5.5V supply range, and 100-TQFP (14x14) package meet the board-level electrical and mechanical constraints. The 86 I/O pins, 16x10b A/D converters, and EBI/EMI, I2C, SPI, and UART/USART interfaces support designs with multiple external peripherals, while the internal oscillator, Brown-out Detect/Reset, POR, PWM, and WDT peripherals should be mapped against the required system functions. The 128KB (64K x 16) FLASH, 8K x 8 RAM, and 4K x 8 EEPROM sizes define the available program memory, RAM, and EEPROM storage budget.
