The Microchip ATTINY104-SSFR is a compact 8-bit AVR microcontroller with 1KB of Flash and 32 bytes of SRAM. It runs at up to 12MHz from a 1.8V to 5.5V supply, packaged in a 14-SOIC. This MCU includes PWM, a watchdog timer, and power-on reset, making it an economical choice for simple, space-limited applications.
- Ultra-low cost and small memory: Perfect for high-volume, disposable electronics where every cent matters.
- 12MHz operation: Sufficient for basic logic and timing, while consuming less power than faster MCUs.
- 14-SOIC package: Easy to solder manually and compatible with standard breadboards using adapters.
- Wide voltage range: Works with 3.3V and 5V systems without level shifters, simplifying design.
Simple LED Flashers and Toys
With 1KB Flash and 12MHz speed, it can generate blinking patterns or sound effects in low-cost consumer products, powered directly from 2xAA batteries.
Battery Management in Small Devices
The 1.8V minimum voltage allows monitoring of a single-cell Li-ion battery, triggering alerts via PWM-driven buzzers or LEDs.
Sensor Trigger Modules
In security systems, the ATTINY104 can read a PIR sensor and activate an alarm, using the WDT to recover from false triggers.
White Goods Timers
For washing machines or microwaves, this MCU can handle simple timing sequences and relay control, with the 14-SOIC package fitting on existing PCBs.
Educational Kits
Its simplicity and DIP-compatible SOIC footprint make it ideal for teaching embedded basics, with minimal external components required.
Remote Control Receivers
At 12MHz, it can decode IR signals from remote controls, providing a low-cost solution for TV or fan control.
