MCHPATMEGA128-16AUR
Overview
The ATMEGA128-16AUR is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 128KB of programmable flash memory and 4KB of SRAM. It operates at a maximum frequency of 16MHz and is designed to execute powerful instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz. This device is housed in a 64-pin TQFP package and includes a wide range of peripherals such as an 8-channel 10-bit ADC, JTAG interface for on-chip debugging, and multiple serial communication interfaces.
Why Choose This Part
This microcontroller balances a large memory footprint with a robust peripheral set, including an on-chip 2-cycle multiplier and JTAG boundary-scan for simplified testing. Its highly efficient RISC architecture allows for significant processing power at relatively low clock speeds, optimizing power consumption across its six software-selectable sleep modes.
Applications
Key Specifications
Getting Started
Engineers can begin development using the Microchip Studio (formerly Atmel Studio) IDE and the AVR GCC toolchain. Hardware debugging and programming are typically performed via the JTAG interface using the Atmel-ICE or a similar AVR-compatible programmer. Evaluation can be accelerated using standard AVR development boards that support 64-pin TQFP footprints.
