The Microchip ATTINY406-MFR is a low-power 8-bit AVR microcontroller in a compact 20-VFQFN package. It delivers 4KB flash memory and 256B SRAM, operating at up to 16MHz with a wide 2.7V-5.5V supply range. Integrated brown-out detection, power-on reset, and watchdog timer enhance system reliability in demanding environments. Rated for -40°C to 125°C, it suits industrial and automotive applications requiring robust performance in minimal space.
- Wide voltage range (2.7V-5.5V) simplifies power supply design across 3.3V and 5V systems.
- High-temperature tolerance (125°C) enables use in harsh automotive and industrial settings.
- Compact 20-VFQFN package saves PCB area for space-constrained designs.
- Integrated WDT and brown-out reset improve system reliability without external components.
Battery-Powered Sensor Nodes
