ATTINY45-20XUR

Overview

The ATTINY45-20XUR is an 8-bit AVR microcontroller featuring 4K bytes of In-System Programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. It operates at a maximum clock frequency of 20 MHz within the 2.7V to 5.5V supply voltage range. The device includes a 10-bit ADC with four single-ended channels, two high-frequency PWM outputs, and six programmable I/O lines. It utilizes an 8-pin TSSOP package.

Feature Summary

Advanced RISC architecture executing most instructions in a single clock cycle for efficient processing.
Non-volatile memory with high endurance capabilities for program and data storage.
Integrated peripheral features including timers, counters, and analog-to-digital conversion.
Supports multiple power-saving modes to optimize energy consumption.

Applications

Battery-powered embedded systems requiring low power consumption
Simple control applications utilizing the integrated ADC and PWM
Industrial environments operating within the specified temperature range

Procurement Notes

Verify the specific speed grade and package configuration against project requirements. Confirm that the 20 MHz performance aligns with the intended supply voltage conditions. Ensure compatibility with existing development tools and programming interfaces before finalizing procurement decisions.

Selection Notes

Select this component when 4K Flash and 256 bytes of RAM are sufficient for application logic. Consider the TSSOP package constraints for PCB layout. Evaluate the need for the 20 MHz speed grade versus lower speed options if power savings are prioritized over processing throughput.

Part Context

This part belongs to the ATtiny45 family within the broader AVR microcontroller portfolio. It shares architectural similarities with the ATtiny25 and ATtiny85 variants, differing primarily in memory capacities. The device is designed for cost-sensitive applications requiring reliable 8-bit processing capabilities.
