ATTINY85-20PU Microcontroller 8KB Flash 20MHz DIP-8 Socket

Description

Product Overview

The ATTINY85-20PU microcontroller from risingsaplings is a compact 8‑pin DIP‑8 device that delivers a balanced mix of performance, power efficiency, and ease of integration. Featuring 8 KB of flash memory and 512 B of SRAM, it provides ample space for code and data in a variety of embedded applications. Operating at frequencies up to 20 MHz, the chip can handle demanding timing requirements while maintaining a low‑power profile suitable for battery‑operated devices. Its operating voltage range of 2.7 V to 5.5 V makes it compatible with both 3.3 V and 5 V logic levels, offering flexibility for designers working with diverse power supplies. The inclusion of an on‑board socket simplifies prototyping and testing, allowing developers to swap the IC without soldering, which reduces development time and cost. Additional built‑in peripherals such as a brown‑out detector, power‑on reset, pulse‑width modulation (PWM) channels, and a watchdog timer enhance reliability and enable sophisticated control schemes without external components. The package dimensions of 2.36 × 3.54 × 0.39 inches and a weight of 0.32 oz ensure that the component fits comfortably on standard breadboards and PCBs, while the robust construction guarantees durability in both hobbyist and industrial environments. This microcontroller is part of the AVR family, known for its efficient instruction set and widespread support in development tools, making it an ideal choice for engineers, makers, and educators seeking a versatile and cost‑effective solution.

Usage

The ATTINY85-20PU excels in a broad range of applications where size, power consumption, and functionality are critical. Its compact form factor and socketed design make it perfect for rapid prototyping in educational settings, allowing students to experiment with embedded programming without the need for soldering equipment. In hobbyist projects, the microcontroller can drive LED displays, control small motors, manage sensor data, and implement communication protocols such as I²C and SPI, thanks to its versatile I/O pins. For low‑power IoT devices, the 2.7‑5.5 V operating range and built‑in brown‑out detection help preserve battery life while ensuring reliable operation under fluctuating power conditions. The PWM channels are well suited for dimming LEDs, generating audio tones, or controlling servo motors in robotics projects. Additionally, the watchdog timer provides a safety net for unattended deployments, automatically resetting the system in case of software hangs. The DIP‑8 package with an included socket also facilitates integration into custom PCBs for wearable electronics, remote sensors, and compact control units where board space is at a premium. Whether you are building a simple temperature logger, a wireless button, or a more complex motor controller, the ATTINY85-20PU offers the necessary features to bring your concept to life with minimal overhead.
