The Microchip ATTINY20-XUR is an 8-bit AVR microcontroller in a 14-pin TSSOP package. It operates from 1.8V to 5.5V and runs at up to 12MHz. With 2KB of Flash and 128 bytes of SRAM, it is designed for simple control and monitoring tasks. Integrated features include an ADC, PWM, watchdog timer, and brown-out detection, making it a reliable choice for compact embedded systems.
- Ultra-low power consumption: Supports 1.8V operation, extending battery life in portable devices.
- Compact footprint: 14-TSSOP package saves PCB space for miniaturized designs.
- Integrated analog: Built-in ADC eliminates the need for external converter chips.
- Robust protection: Brown-out reset and watchdog timer improve system reliability.
Battery-Powered Sensor Nodes
The 1.8V minimum supply voltage and low-power sleep modes enable long battery life in IoT sensor nodes that wake periodically to read sensors and transmit data.
Compact LED Lighting Controllers
With PWM channels and a 14-TSSOP package, the ATTINY20-XUR can drive LED dimming and color control in small form-factor lighting modules.
Portable Consumer Electronics
Its 12MHz speed and 2KB Flash are sufficient for debouncing buttons, managing simple user interfaces, and controlling haptic feedback in wearables.
Automotive Interior Ambient Lighting
Operating from -40°C to 85°C, it can handle under-dash lighting control and seat position memory in vehicles, using its EEPROM for data retention.
Industrial Sensor Signal Conditioning
The built-in ADC and brown-out reset ensure reliable reading of temperature or pressure sensors in factory automation, even with noisy power rails.
Smart Home Thermostat Interfaces
It can manage a small LCD, read a rotary encoder, and control a relay for HVAC systems, all within a minimal component count.
