ATTINY25V-10MU

Overview

The ATTINY25V-10MU is an 8-bit AVR microcontroller featuring a 2 KB In-System Programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates within a voltage range of 1.8 V to 5.5 V with a maximum clock frequency of 10 MHz. The device utilizes a 20-pad QFN/MLF package (20M1) and supports industrial temperature ranges up to +105°C.

Feature Summary

• AVR enhanced RISC architecture with single-cycle execution for optimized power consumption
• In-system programmable via SPI port for flexible firmware updates
• Integrated Universal Serial Interface (USI) supporting multiple communication protocols
• Four-channel 10-bit Analog-to-Digital Converter (ADC) with differential inputs

Applications

• Industrial control systems requiring low-power operation
• Battery-powered embedded devices utilizing picoPower technology
• Sensor interfaces using the integrated ADC and USI capabilities
• General-purpose logic replacement in compact surface-mount designs

Procurement Notes

Verify that the specific ordering code matches the required speed grade and temperature rating. Confirm the package type corresponds to the 20-pad QFN/MLF designation. Ensure compatibility with existing PCB footprints and thermal management requirements for the exposed pad connection.

Selection Notes

Select this component when a balance of processing speed and low power consumption is required. The 10 MHz speed grade at 1.8 V makes it suitable for battery-operated applications. Consider the 20-pin form factor if additional I/O or thermal dissipation through the exposed pad is necessary compared to smaller packages.

Part Context

This part belongs to the ATtiny25/V family, which shares core architectural features with the ATtiny45 and ATtiny85. The primary distinctions lie in the non-volatile memory capacities. The 'V' suffix indicates support for extended low-voltage operation down to 1.8 V, while the '10' denotes the 10 MHz speed grade.
