Overview

The ATTINY84A-SSUR is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 8KB of ISP flash memory and 512 bytes of SRAM. Operating at speeds up to 20MHz, this device balances processing throughput with minimal power consumption in a compact 14-pin SOIC package.

Why Choose This Part

This MCU offers a versatile peripheral set, including 12 GPIO pins and a Universal Serial Interface (USI) in a small footprint. It provides an excellent performance-to-power ratio for cost-sensitive designs requiring more I/O than the 8-pin ATtiny series.

Applications

Simple Sensor Nodes
Ideal for reading analog sensors via its 10-bit ADC and transmitting data over basic serial interfaces.
Handheld Battery Devices
Utilizes picoPower technology to achieve extremely low current draw in sleep modes, extending battery life in portable electronics.
Interface Bridging
Commonly used to manage I/O expansion or protocol conversion between a host processor and peripheral components.

Getting Started

Developers can program this chip using the Microchip Studio or MPLAB X IDEs with an AVR Dragon or Atmel-ICE programmer. The part is fully supported by the AVR-GCC toolchain and can be integrated into the Arduino environment using third-party hardware cores like ATTinyCore.
