Overview
The ATtiny827-MFR is an 8-bit microcontroller from the Microchip tinyAVR® 2 family, featuring a 24-pin VQFN package. It integrates 8 KB of Flash memory, 1 KB of SRAM, and 128 B of EEPROM. The device operates at a maximum frequency of 20 MHz with a supply voltage range of 1.8V to 5.5V. Key peripherals include a 12-bit differential ADC with PGA, two USARTs, SPI, TWI, four CCL LUTs, and an Event System.
Feature Summary
- Features a high-performance low-power AVR CPU with hardware multiplier and single-cycle I/O access.
- Includes advanced analog capabilities such as a 12-bit differential ADC with Programmable Gain Amplifier (PGA).
- Supports flexible inter-peripheral signaling through a dedicated Event System.
- Provides Configurable Custom Logic (CCL) with programmable Look-Up Tables for logic implementation.
Applications
- Real-time control systems requiring low power consumption.
- Applications needing precise analog signal acquisition via differential ADC.
- Industrial environments utilizing extended temperature ranges (-40°C to +125°C).
Procurement Notes
Verify the specific ordering suffix 'MFR' corresponds to the required tape and reel packaging and industrial temperature grade. Confirm that the 24-pin VQFN footprint matches the target PCB design. Ensure compatibility with the UPDI programming interface for development and production flashing.
Selection Notes
Select this component when vertical migration within the tinyAVR 2 family is desired without code modification. Choose this part if 22 general-purpose I/O pins are required alongside extensive peripheral support. Consider this MCU for designs needing a balance of processing speed and energy efficiency in compact packages.
Part Context
This device belongs to the tinyAVR® 2 family, which shares pin and feature compatibility across variants. It utilizes the latest Microchip technologies for flexible architecture. The family supports horizontal migration to reduce pin counts or vertical migration to increase resources while maintaining software compatibility.
Replacement Considerations
Compatible substitutes include other members of the tinyAVR® 2 family such as ATtiny826 or ATtiny824, provided pin count and memory requirements align. Verify that alternative parts meet the same electrical characteristics and package dimensions for direct replacement.
