ATTINY25V-10MF

Overview

The ATTINY25V-10MF is an 8-bit AVR microcontroller featuring a high-performance RISC architecture with 2KB of in-system programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates within a supply voltage range of 1.8V to 5.5V and supports clock frequencies up to 10MHz at 2.7V–5.5V or 4MHz at 1.8V–5.5V. The device includes six programmable I/O lines, a 4-channel 10-bit ADC, USI, and multiple timer/counters. It is housed in a 20-pad QFN/MLF package (20M1) and is rated for industrial temperature ranges extending to +125°C.

Feature Summary

• AVR enhanced RISC core executing powerful instructions in single clock cycles
• Non-volatile memory with 10,000 Flash write/erase cycles and 100,000 EEPROM cycles
• Integrated Universal Serial Interface (USI) supporting SPI and TWI protocols
• Programmable Watchdog Timer with separate on-chip oscillator

Applications

• Industrial control systems requiring extended temperature stability
• Battery-powered embedded devices utilizing low power modes
• Sensor interfaces using the integrated 10-bit ADC
• Communication nodes using USI-based serial protocols

Procurement Notes

Verify the specific suffix 'MF' corresponds to the 20-pad QFN/MLF package and the +125°C industrial temperature rating as defined in the ordering information table. Confirm that the 'V' designation indicates the 1.8V minimum operating voltage capability. Ensure the source documentation explicitly lists this part number variant before procurement.

Selection Notes

Select this component when an 8-bit AVR MCU is required with 2KB Flash and operation at temperatures up to 125°C. The 20-pin QFN package is suitable for space-constrained surface mount designs. Consider the 1.8V operating range if the system requires lower voltage operation compared to standard 2.7V variants.

Part Context

This device belongs to the ATtiny25/V family, which shares architectural similarities with the ATtiny45 and ATtiny85. The primary distinction lies in the Flash memory size, with the ATtiny25 offering 2KB. The 'V' suffix denotes support for 1.8V operation, while the 'MF' suffix identifies the specific 20-pad QFN package and high-temperature industrial grade.

Replacement Considerations

ATtiny25V-10MFR is the tape and reel version of the same component.
