ATMEL ATTINY85-20SU Microcontroller, 8Bit, SOIC8 - 20MHz

The ATMEL ATTINY85-20SU is a high-performance, low-power 8-bit AVR RISC-based microcontroller designed for a wide range of embedded applications. It combines advanced RISC architecture with non-volatile program and data memories, delivering efficient processing and flexible integration. With a throughput of up to 20 MIPS at 20 MHz, this device balances power consumption and processing speed, making it an ideal choice for battery-powered and energy-conscious designs.

The microcontroller operates within a supply voltage range of 2.7 to 5.5V and features 32 general purpose working registers, an 8-bit timer/counter with compare modes, a high-speed 8-bit timer/counter, a Universal Serial Interface (USI), and a 4-channel 10-bit A/D converter. It also includes external and internal interrupts, a programmable watchdog timer with an internal oscillator, and three software-selectable power saving modes: Idle, ADC Noise Reduction, and Power-down. For development, the device supports debugWIRE for on-chip debugging and is in-system programmable via SPI port.

This microcontroller is housed in an 8-pin SOIC package and provides 6 general purpose I/O lines. Its low-power consumption is exceptional, with 300µA active mode at 1MHz and 1.8V, and a power-down mode that draws only 0.1µA at 1.8V. The device is suitable for a wide temperature range from -40°C to 85°C, ensuring reliable performance in demanding environments. Its small footprint and robust feature set make it a versatile choice for automation, communication, consumer electronics, motor control, industrial, and sensing applications.

The AVR ATtiny85 series is known for its ease of use and extensive community support, backed by the reliability of the ATMEL brand. Whether you are prototyping a new design or building a production-ready system, the ATTINY85-20SU provides a balance of performance, efficiency, and functionality.
