The Microchip ATTINY20-MMHR is a low-power 8-bit AVR microcontroller in a tiny 20-VFQFN package. It delivers 2KB of flash memory and 128 bytes of RAM, running at up to 12MHz. With a supply range of 1.8V to 5.5V, it integrates essential features like Brown-out Detect/Reset, POR, PWM, and WDT. This MCU is engineered for compact, energy-efficient designs requiring reliable performance in harsh environments.
- Ultra-compact footprint: The 20-VFQFN exposed pad package minimizes PCB area, enabling miniaturized product designs.
- Wide voltage flexibility: 1.8V to 5.5V operation supports both 3.3V and 5V systems without external level shifters.
- Integrated safety features: Brown-out Reset and WDT prevent system lockups and ensure reliable long-term operation.
- Low-power consumption: Optimized for battery life with multiple sleep modes and fast wake-up times.
Battery-Powered Sensor Nodes
The 1.8V minimum supply voltage and low-power sleep modes allow the ATTINY20-MMHR to run directly from coin cells or two AA batteries, extending operational life in IoT sensors.
Compact Motor Control
With built-in PWM channels and a 12MHz AVR core, this MCU can generate precise control signals for small DC or brushless motors in drones and robotics.
Portable Consumer Electronics
The 20-VFQFN package (3x3mm) and 2KB flash make it ideal for e-cigarettes, wearables, and small handheld devices where board space is critical.
LED Lighting Systems
PWM outputs enable smooth dimming and color mixing in LED strips or indicators, while the WDT ensures reliable operation in always-on lighting fixtures.
Automotive Interior Accessories
Operating from -40°C to 85°C, it can handle under-dash lighting, seat control modules, or window switch interfaces in vehicles.
Security and Alarm Keypads
The POR and Brown-out Reset guarantee clean startup, and the 128 bytes of RAM are sufficient for debouncing keys and managing simple alarm logic.
