ATTINY826-MF

Overview

The ATtiny826-MF is an 8-bit microcontroller from the Microchip tinyAVR 2 family, featuring a 20 MHz AVR CPU with hardware multiplier. It provides 8 KB of Flash memory, 1 KB of SRAM, and 128 B of EEPROM. The device includes a 12-bit differential ADC with PGA, up to 18 general-purpose I/O pins, and supports multiple communication interfaces including USART, SPI, and TWI. Operating voltage ranges from 1.8 V to 5.5 V, with industrial temperature coverage.

Feature Summary

• Features a high-performance low-power AVR CPU running at up to 20 MHz with single-cycle I/O access and a two-cycle hardware multiplier.
• Includes advanced analog peripherals such as a 12-bit differential ADC with Programmable Gain Amplifier (PGA) and up to 15 input channels.
• Supports flexible inter-peripheral signaling through an Event System and Configurable Custom Logic (CCL) with four programmable Look-Up Tables.
• Offers versatile connectivity with dual USARTs, host/client SPI, and host/client TWI with dual address match capabilities.

Applications

• Industrial control systems requiring robust peripheral integration
• Battery-powered devices utilizing low-power sleep modes
• Sensor nodes using event-driven architectures
• Embedded applications needing secure code protection via lockbits

Procurement Notes

Verify the specific ordering suffix 'MF' corresponds to the VQFN package and extended temperature range (-40°C to +125°C) as defined in the datasheet naming convention. Confirm that the manufacturer part number matches the exact pin count and memory configuration required for your design. Ensure compatibility with UPDI programming tools for development and debugging.

Selection Notes

Select this component when vertical migration within the tinyAVR 2 family is desired without code modification. Choose this model if the application requires 8 KB of Flash and 1 KB of SRAM in a 20-pin package. Consider this device for designs needing a 12-bit ADC with PGA and extensive I/O options compared to smaller pin-count variants.

Part Context

This microcontroller belongs to the tinyAVR 2 family, which shares architectural similarities with other members like the ATtiny824 and ATtiny827. These devices are fully pin and feature compatible, allowing for easy scaling across different package sizes and memory configurations while maintaining software compatibility.

Replacement Considerations

Compatible replacements include other members of the tinyAVR 2 family such as ATtiny824 or ATtiny827, provided pin counts and memory requirements align. Verify package type and temperature range specifications before substitution to ensure physical and environmental compatibility.
