MCHPATMEGA1280-16AU
Overview
The ATMEGA1280-16AU is a high-performance, low-power 8-bit RISC microcontroller featuring 128KB of Flash memory and 8KB of SRAM. It operates at up to 16MHz and provides an extensive peripheral set including 16-channel 10-bit ADC, four UARTs, and multiple timers in a 100-pin TQFP package. This device is designed for applications requiring high I/O counts and substantial program space within the proven AVR architecture.
Why Choose This Part
This MCU offers a high pin-to-memory ratio, providing 86 general-purpose I/O lines for complex hardware interfacing. It features a true Read-While-Write operation and a 2-cycle hardware multiplier that significantly speeds up arithmetic operations compared to smaller 8-bit cores. The device also maintains excellent data retention of 20 years at 85C, making it suitable for long-lifecycle industrial products.
Applications
Getting Started
Development is best supported through Microchip Studio or the MPLAB X IDE using the XC8 compiler. Hardware debugging and programming can be performed using the Atmel-ICE or Power Debugger via the JTAG or ISP interfaces. For rapid prototyping, this chip is the core processor used in the Arduino Mega 1280 platform.
