ATTINY25V-10MFR

Overview

The ATTINY25V-10MFR is an 8-bit AVR microcontroller featuring 2 KB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates at a maximum clock frequency of 10 MHz within a supply voltage range of 1.8 V to 5.5 V. The device includes a 4-channel 10-bit ADC, USI interface, and two PWM channels. It is housed in a 20-pad QFN/MLF package (20M1) and supports industrial temperature ranges up to +125°C.

Feature Summary

• AVR enhanced RISC architecture with single-cycle execution
• In-system programmable via SPI port
• Low power consumption with multiple sleep modes
• Integrated analog comparator and programmable watchdog timer

Applications

• Industrial control systems requiring extended temperature stability
• Battery-powered embedded devices utilizing low-voltage operation
• Sensor interfaces using the integrated 10-bit ADC
• General-purpose logic replacement in compact surface-mount designs

Procurement Notes

Verify the specific ordering suffix 'MFR' corresponds to the 20-pad QFN/MLF package and the +125°C industrial temperature rating. Confirm that the 'V' designation aligns with the required 1.8V minimum operating voltage for your application. Ensure compatibility with existing PCB footprints for the 20M1 package type before finalizing procurement.

Selection Notes

Select this component when high-temperature reliability up to 125°C is mandatory alongside low-voltage operation down to 1.8V. The 20-pad QFN package offers a compact footprint suitable for space-constrained designs. Consider the 10 MHz speed grade sufficient for applications not requiring the higher 20 MHz performance available in non-V variants.

Part Context

This part belongs to the ATtiny25/V family, which shares core specifications with the ATtiny45 and ATtiny85. The primary differentiator is the program memory size; the ATTINY25V variant provides 2 KB of Flash compared to larger capacities in other family members. All variants utilize the same pinout and peripheral set, facilitating design scalability.
