ATTINY20-XUR

Overview

The ATTINY20-XUR is an 8-bit AVR microcontroller featuring a RISC core with 2 KB of in-system programmable Flash memory and 128 bytes of SRAM. It operates within a supply voltage range of 1.8 V to 5.5 V and supports clock frequencies up to 12 MHz. The device includes a 10-bit ADC, 12 I/O lines, and multiple communication interfaces including SPI and I2C. Packaged in a 14-lead TSSOP, it functions across an industrial temperature range.

Feature Summary

• Integrates a high-performance 8-bit AVR RISC architecture for efficient code execution.
• Provides non-volatile program storage via in-system programmable Flash technology.
• Includes analog-to-digital conversion capabilities with 10-bit resolution.
• Supports serial communication protocols such as SPI and I2C for peripheral connectivity.

Applications

• Battery-powered embedded systems requiring low voltage operation
• Industrial control modules utilizing serial communication interfaces
• Sensor interface circuits incorporating analog signal processing

Procurement Notes

Verify the suffix 'XUR' corresponds to the specific 14-lead TSSOP package variant. Confirm the operating temperature grade matches industrial requirements. Check current lifecycle status as some Atmel devices may be marked as not recommended for new designs. Ensure compatibility with existing PCB footprints and programming interfaces before procurement.

Selection Notes

Select this component when a compact 8-bit solution with integrated ADC is required. Compare against other ATtiny variants based on Flash capacity and pin count needs. Consider the 1.8 V minimum supply voltage for battery applications. Verify that the 12 MHz maximum frequency meets timing constraints for the target application logic.

Part Context

This part belongs to the Microchip (formerly Atmel) ATtiny family of 8-bit microcontrollers. These devices are designed for cost-sensitive applications requiring moderate performance and low power consumption. The series typically offers various memory sizes and package options to suit different design constraints while maintaining a common instruction set architecture.

Replacement Considerations

Consult official Microchip documentation for verified cross-reference part numbers. Ensure any substitute maintains identical pinout, voltage specifications, and package dimensions. Verify software compatibility if migrating between different memory capacities within the same family.
