ATTINY85-20PU DIP-8 Microcontroller with 8K Bytes Brand New and Original(BT)

Description

🔍 Product Overview

The ATTINY85-20PU is a compact, high-performance 8-bit AVR microcontroller from Microchip (formerly Atmel). Despite its small size, it packs powerful features — 8 KB of Flash memory, 512 B SRAM, 512 B EEPROM, and multiple peripherals — making it a favorite for small, low-power, and cost-sensitive embedded projects.

🚀 Why It’s Ideal for Your Projects

• Tiny yet powerful: Designed for projects where space is limited but performance matters — from wearable devices to custom automation.

• Low power consumption: Excellent for battery-operated designs thanks to multiple sleep modes and efficient operation up to 20 MHz.

• Flexible I/O: Each of the 6 I/O pins can serve multiple functions, such as ADC, PWM, or serial communication.
