Overview

The ATTINY84A-SSF is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 8KB of flash memory, 512B of EEPROM, and 512B of SRAM. It operates at speeds up to 20MHz and includes an on-chip analog-to-digital converter, a temperature sensor, and a Universal Serial Interface (USI) in a compact 14-pin SOIC package.

Why Choose This Part

This MCU offers a high code density for its 8KB flash size, allowing complex logic in a small footprint. Its extremely low power consumption (210 uA at 1.8V/1MHz) and fast wake-up times make it an excellent choice for energy-harvesting and battery-critical designs.

Applications

Battery-Powered Sensing
Utilizes ultra-low power modes and 0.1 uA shutdown current for long-term monitoring applications.
Industrial Signal Conditioning
The integrated 10-bit ADC and on-chip temperature sensor enable localized analog data processing.
System Supervisory Circuits
Features brown-out detection and a programmable watchdog timer to monitor larger host processors.
Portable Consumer Electronics
Ideal for basic UI control and PWM signal generation in space-constrained handheld devices.
