ATTINY826-MFR

Overview

The ATtiny826-MFR is an 8-bit microcontroller from the tinyAVR® 2 family, utilizing the AVR CPU with a hardware multiplier. It features 8 KB of Flash memory, 1 KB of SRAM, and 128 B of EEPROM. The device operates at a maximum clock frequency of 20 MHz and supports a supply voltage range of 1.8 V to 5.5 V. It includes a 12-bit differential ADC with PGA, up to 18 general-purpose I/O pins, and multiple communication interfaces including USART, SPI, and TWI.

Feature Summary

• High-performance low-power architecture with single-cycle I/O access and two-level interrupt controller
• Integrated Event System for CPU-independent peripheral signaling and Configurable Custom Logic (CCL)
• Advanced analog capabilities featuring a 12-bit differential ADC with Programmable Gain Amplifier (PGA)
• Single-pin Unified Program and Debug Interface (UPDI) for programming and debugging

Applications

• Industrial control systems requiring robust I/O and programmable logic
• Battery-powered devices benefiting from low-power sleep modes and efficient CPU performance
• Sensor interface applications utilizing high-resolution differential ADC inputs
• Communication nodes employing USART, SPI, or TWI protocols

Procurement Notes

Verify the specific package type associated with the MFR suffix against official Microchip documentation, as ordering suffixes can indicate variations in tape-and-reel packaging or temperature grades. Confirm that the component matches the required industrial or extended temperature specifications for your application environment before finalizing procurement.

Selection Notes

Select this model when 8 KB of program memory and 1 KB of SRAM are sufficient for the application logic. It is suitable for designs requiring up to 18 I/O pins and advanced analog features like the 12-bit ADC with PGA. Consider vertical migration within the tinyAVR® 2 family if future pin count expansion is needed without code modification.

Part Context

This component belongs to the tinyAVR® 2 family, which offers vertical migration compatibility across different pin counts and memory sizes. The ATtiny826 provides a balance of processing power and peripheral richness, positioned between the smaller ATtiny426 and larger variants in terms of memory resources while maintaining the same core architecture.
