ATTINY25V-10SUR

Overview

The ATTINY25V-10SUR is an 8-bit AVR microcontroller featuring 2KB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates at speeds up to 10MHz with a supply voltage range of 1.8V to 5.5V. The device includes six programmable I/O lines, a 4-channel 10-bit ADC, USI, two PWM channels, and an internal calibrated oscillator. It is housed in an 8-SOIC package and supports industrial temperature ranges.

Feature Summary

• High-performance 8-bit AVR architecture with single-cycle execution for optimized power consumption
• Non-volatile memory with high endurance for program flash and EEPROM data retention
• Integrated analog-to-digital converter with multiple channel options and programmable gain
• Universal Serial Interface (USI) supporting standard SPI and I2C communication protocols

Applications

• Battery-powered embedded systems requiring low active and power-down current modes
• Industrial control applications utilizing the Universal Serial Interface for sensor communication
• Consumer electronics using the internal calibrated oscillator for cost-effective clocking solutions
• Automotive or harsh environment devices operating within extended industrial temperature specifications

Procurement Notes

Verify the specific speed grade suffix '10' corresponds to the required 10MHz operational frequency at your target supply voltage. Confirm the 'SUR' suffix indicates tape and reel packaging suitable for automated surface-mount assembly. Ensure the component meets RoHS compliance requirements for your manufacturing process.

Selection Notes

Select this variant when a 1.8V minimum supply voltage is necessary, distinguishing it from non-V versions that require 2.7V. Consider the 8-SOIC package dimensions for PCB layout constraints. Evaluate the 6 available I/O pins against system interface requirements before choosing over higher-pin-count family members.

Part Context

This component belongs to the ATtiny25/45/85 series of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares the same core architecture and peripheral set as the ATtiny45V and ATtiny85V, differentiated primarily by program memory capacity. The V-series designation specifically enables operation down to 1.8V.

Replacement Considerations

ATtiny25V-10SU serves as a tube-packaged alternative. ATtiny25V-10SSUR provides a narrow-body SOIC option. For non-low-voltage applications, ATtiny25-10SUR offers identical functionality with a 2.7V minimum supply requirement.
