We can break Atmel MCU ATMEGA1281 locked heximal, please view the Atmel MCU ATMEGA1281 features for your reference:
The ATMEGA1281 provides the following features: 4K/8Kbytes of In-System Programmable Flash with Read-While-Write capabilities, 256/512/512/1Kbytes EEPROM, 512/1K/1K/2Kbytes SRAM when break Atmel MCU.
23 general purpose I/O lines, 32 general purpose working registers, three flexible Timer/Counters with compare modes, internal and external interrupts, a serial programmable USART, a byte-oriented 2-wire Serial Interface.
an SPI serial port, a 6-channel 10-bit ADC (8 channels in TQFP and QFN/MLF packages), a programmable Watchdog Timer with internal Oscillator, and five locked heximal selectable power saving modes.
The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, USART, 2-wire Serial Interface, SPI port, and interrupt system to continue functioning.
The Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or hardware reset. In Power-save mode, the asynchronous timer continues to run, allowing the user to maintain a timer base while the rest of the device is sleeping when Break Atmel MCU ATmega1281 Locked Heximal.
The ADC Noise Reduction mode stops the CPU and all I/O modules except asynchronous timer and ADC, to minimize switching noise during ADC conversions.
In Standby mode, the crystal/resonator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up combined with low power consumption.
Atmel® offers the QTouch® library for embedding capacitive touch buttons, sliders and wheels functionality into AVR® Atmel MCUs.
The patented charge-transfer signal acquisition offers robust sensing and includes fully debounced reporting of touch keys and includes Adjacent Key Suppression® (AKS™) technology for unambiguous detection of key events when Break Atmel MCU ATmega1281 Locked Heximal.
The easy-to-use QTouch Suite toolchain allows you to explore, develop and debug your own touch applications when BREAK IC.
