ATTINY824-XU

Overview

The ATtiny824-XU is an 8-bit AVR microcontroller from the tinyAVR 2 family, featuring 8 KB of Flash memory, 1 KB of SRAM, and 128 B of EEPROM. It operates at a maximum frequency of 20 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit differential ADC with PGA, up to 18 general-purpose I/O pins, and supports interfaces such as USART, SPI, and TWI. It utilizes a TSSOP/SSOP package (suffix X) and offers industrial temperature range options.

Feature Summary

• Features a high-performance low-power AVR CPU with hardware multiplier and single-cycle I/O access.
• Includes advanced analog peripherals like a 12-bit differential ADC with Programmable Gain Amplifier.
• Supports flexible inter-peripheral signaling through an integrated Event System.
• Provides secure programming via a single-pin Unified Program and Debug Interface (UPDI).

Applications

• Industrial control systems requiring robust peripheral integration
• Battery-powered devices utilizing low-power architecture
• Sensor nodes using event-driven processing
• Embedded applications needing secure code protection

Procurement Notes

Verify the specific suffix requirements for your design, as ordering codes include carrier type indicators like 'R' for tape and reel. Confirm that the selected package variant matches your PCB footprint constraints. Ensure compatibility with existing UPDI programmers for development and production programming workflows.

Selection Notes

Select this component when 8 KB of program memory and 1 KB of data RAM are sufficient for the application logic. Consider the ATtiny824-XU for designs requiring a 14 or 20-pin form factor with extensive analog capabilities. Evaluate the 20 MHz performance against power consumption needs in varying voltage environments.

Part Context

This part belongs to the tinyAVR 2 family, which emphasizes vertical migration compatibility within the series. The device shares architectural similarities with other members like the ATtiny424 and ATtiny826, allowing for scalable design transitions based on pin count and memory requirements without code modification.

Replacement Considerations

Compatible replacements within the same family include ATtiny424-XU for reduced memory configurations. For higher memory needs, consider ATtiny826-XU or ATtiny827-XU variants. Verify pinout compatibility before substituting to ensure seamless integration into existing hardware layouts.
