ATMEL Chip Unlock: Attiny, AT90, and ATmega Series

Atmel chips

What Is ATMEL Chips?

Atmel chips include both AVR and ARM cores. Among them, AVR includes Attiny series, AT90 series and ATmega series. ARM includes AT91 series.

Attiny Series

Atmel’s Attiny microcontroller integrates Atmel’s AVR microcontroller, flash memory, and SRAM. ATtiny series chips use Atmel’s patented picoPower technology with extremely low power consumption. The system clock frequency is controlled by software to achieve the best balance between system performance and power consumption. Additionally, these devices support SPI and TWI (with I2C-compatibility) communication for maximum flexibility.
