ATTINY824-XFR

Overview

The ATTINY824-XFR is an 8-bit microcontroller from the Microchip tinyAVR 2 family, utilizing the AVR CPU with a hardware multiplier. It features 8 KB of Flash memory, 512 B of SRAM, and 128 B of EEPROM. The device operates at a maximum clock frequency of 20 MHz within a supply voltage range of 1.8 V to 5.5 V. It includes a 12-bit differential ADC with PGA, up to 12 general-purpose I/O pins, and supports industrial temperature ranges (-40°C to +85°C or -40°C to +125°C). The 'X' suffix indicates a TSSOP/SSOP package, while 'F' denotes extended temperature capability.

Procurement Notes

Verify the specific ordering suffixes for package type and temperature range, as these define the physical form factor and operational limits. Confirm availability status, noting that certain variants may be designated as Not Recommended for New Designs (NRND). Ensure compatibility with existing design tools and programming interfaces before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring vertical migration within the tinyAVR 2 family without code modification. Consider the pin count and memory size relative to application needs, as horizontal migration reduces available features. Evaluate the need for extended temperature ratings if operating in harsh environments, and ensure the chosen package variant meets PCB layout constraints.

Part Context

This device belongs to the tinyAVR 2 family, which emphasizes flexibility and low power consumption. The family allows for easy migration between devices with different pin counts and memory sizes. The ATTINY824 specifically offers a balance of processing power and peripheral richness suitable for compact embedded applications.

Replacement Considerations

Devices within the same family, such as ATtiny424 or ATtiny826, offer pin and feature compatibility for vertical migration. Check datasheet DS40002311A for detailed comparison of memory sizes and pin configurations to ensure functional equivalence in existing designs.
