The Microchip ATTINY45-15ST is a compact 8-bit AVR microcontroller designed for simple, cost-effective embedded tasks. It operates from 2.7V to 5.5V and runs at up to 16MHz, offering reliable performance for basic control functions. With 4KB of flash and 256 bytes of SRAM, it is suitable for small applications like lighting, sensing, and motor control. The 8-pin SOIC package is space-saving and easy to assemble. Integrated Brown-out Detect/Reset, POR, PWM, and WDT ensure stable operation in noisy environments. Its -40°C to +85°C range covers most commercial and industrial uses.
- Small footprint: 8-SOIC package fits tight PCB layouts.
- Wide voltage range: 2.7V to 5.5V simplifies power supply design.
- Integrated PWM: Enables direct control of LEDs and small motors.
- Reliable reset: Brown-out detection and POR prevent data corruption.
- Low cost: Ideal for high-volume consumer products.
LED Lighting Control
PWM outputs and 16MHz speed enable smooth dimming and color mixing in RGB LED strips.
Small Sensor Nodes
With 4KB flash, it can read a temperature sensor and transmit data via I2C or UART in IoT end devices.
