MICROCHIP ATTINY85V-10PU 8-Bit AVR Microcontroller

The MICROCHIP ATTINY85V-10PU is a high-performance, low-power 8-bit microcontroller built on the efficient AVR RISC architecture. It is designed to deliver robust processing capabilities while maintaining minimal power consumption, making it an ideal solution for a wide range of embedded applications. With an impressive throughput of 20 MIPS at 20MHz, this device executes powerful instructions in a single clock cycle, optimising the balance between speed and energy efficiency.

At the heart of the microcontroller is 8KB of in-system programmable (ISP) flash memory for storing your application code, complemented by 512 bytes each of EEPROM and SRAM for data storage and manipulation. The IC integrates a rich set of peripherals, including a 4-channel 10-bit analogue-to-digital converter (ADC), an 8-bit timer/counter, a high-speed 8-bit timer/counter, and a versatile Universal Serial Interface (USI) supporting I2C and SPI communications.

Engineered for reliability in diverse environments, it operates across a broad supply voltage range from 2.7V to 5.5V and can withstand temperatures from -40°C to 85°C. Key features for robust operation include an enhanced power-on reset circuit, a programmable brown-out detection circuit, and a watchdog timer with an internal oscillator. For development flexibility, it includes the debugWIRE on-chip debug system for simplified programming and debugging via an SPI port.

The device offers three software-selectable power-saving modes—Idle, ADC Noise Reduction, and Power-down—allowing designers to fine-tune power consumption for battery-operated or energy-sensitive projects. Its compact 8-pin DIP (Dual In-line Package) through-hole design makes it accessible for prototyping, hobbyist projects, and educational use, as well as for integration into final industrial products.
