ATtiny85 Microcontroller IC DIP 8

ATtiny85 Microcontroller IC DIP 8 

The ATtiny85 is an 8-bit AVR RISC microcontroller developed by Atmel (now Microchip Technology). It belongs to the ATtiny series, which is designed for small, low-power, and cost-effective embedded systems.

The ATtiny85 uses Harvard architecture and a RISC instruction set, allowing most instructions to execute in a single clock cycle. Despite its compact 8-pin DIP package, it integrates Flash memory, SRAM, EEPROM, timers, ADC, PWM, and serial communication, making it suitable for compact control applications and easy prototyping.
