The Microchip ATTINY4-MAHR is an 8-bit AVR microcontroller in a compact 8-UFDFN package. It provides 512 bytes of Flash and 32 bytes of SRAM, running at up to 12MHz. With a wide 1.8V to 5.5V supply range and integrated POR, PWM, and WDT, it is a reliable choice for simple control and monitoring tasks in space-limited designs.
- Ultra-compact 8-UFDFN package: fits in minimal PCB space for miniaturized products.
- Wide voltage range (1.8V-5.5V): simplifies power design and supports battery operation.
- Integrated WDT and POR: enhances system reliability without external components.
- 12MHz AVR core: sufficient processing power for real-time control loops.
Compact Sensor Interfaces
The tiny 8-pin package and low pin count make it ideal for reading analog sensors and converting signals for a main controller.
Battery-Powered Devices
With a 1.8V minimum supply and low-power sleep modes, it extends battery life in wearables and remote monitors.
PWM Motor Control
Its built-in PWM peripheral allows direct speed control of small DC motors or LEDs without external components.
System Supervision
Use the watchdog timer (WDT) and power-on reset (POR) to monitor system health and recover from faults automatically.
Signal Conditioning
The 12MHz AVR core can handle simple filtering or calibration algorithms before sending data to a host system.
Space-Constrained PCBs
The 2mm x 3mm UFDFN package fits into tight layouts where larger MCUs cannot be placed.
