The ATTINY84A-MMH is a compact 8-bit AVR microcontroller housed in a 20-VFQFN package with exposed pad for improved thermal performance. It features 8KB of flash memory and 512 bytes of SRAM, running at up to 20MHz. With a supply voltage range of 1.8V to 5.5V and an operating temperature range of -40°C to 85°C, it is well-suited for space-constrained consumer and IoT applications. Integrated PWM, brown-out detection, and temperature sensor add versatility.
- 20-VFQFN package – ultra-compact footprint for miniaturized designs.
- Exposed pad – enhances heat dissipation for reliable operation.
- 1.8V to 5.5V supply – flexible for battery or regulated power sources.
- 8KB flash with 512B RAM – ample for complex embedded applications.
