Overview

The ATTINY84A-SSU is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 8KB of ISP flash and 512B of SRAM. It is designed for applications requiring small footprints and efficient power consumption, operating at currents as low as 0.21mA at 1.8V and 1 MHz.

Why Choose This Part

This MCU offers a significant memory upgrade over smaller TinyAVR parts while maintaining a low pin count and a broad 1.8V to 5.5V operating range. The inclusion of 512 bytes of EEPROM allows for robust local data logging and calibration storage with a retention rating of up to 100 years at 25C.

Applications

Battery-Powered Sensors
Leverages low-power modes like Power-down and Standby to extend the life of remote sensing nodes.
Handheld Consumer Electronics
Provides sufficient 8KB flash for user interface logic in a compact 14-pin SOIC package.
Signal Conditioning
Utilizes the internal ADC and ADC Noise Reduction mode for processing analog sensor data in industrial environments.
Legacy Logic Replacement
Replaces multiple discrete logic components with a programmable solution that offers 12 pin-change interrupts.
