ATTINY85V-10MUR

Overview

The ATTINY85V-10MUR is an 8-bit AVR microcontroller featuring 8KB of In-System Programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates within a voltage range of 1.8V to 5.5V at speeds up to 10MHz. The device includes a 10-bit ADC with four single-ended channels, a Universal Serial Interface (USI), and six programmable I/O lines. It utilizes a 20-pad QFN/MLF package and supports industrial temperature ranges.

Feature Summary

• Supports low-power consumption with multiple software-selectable sleep modes including power-down and idle.
• Integrates a high-performance 8-bit RISC architecture achieving near 1 MIPS per MHz throughput.
• Includes on-chip debug capabilities via the debugWIRE system for in-system programming.

Applications

• Battery-powered embedded systems requiring extended operational life
• Industrial control interfaces utilizing serial communication protocols
• Sensor data acquisition applications involving analog-to-digital conversion

Procurement Notes

Verify the specific ordering suffix 'R' corresponds to tape and reel packaging requirements for automated assembly processes. Confirm that the 'V' designation aligns with the required 1.8V minimum operating voltage specifications for your target application environment. Ensure compatibility with standard surface mount placement equipment for the 20-pad MLF/QFN package geometry.

Selection Notes

Select this variant when the design requires operation down to 1.8V supply levels, distinguishing it from non-V versions which typically require higher minimum voltages. Consider the 20-pin footprint if board space constraints favor the compact MLF/QFN form factor over traditional leaded packages. Validate that the 8KB program memory capacity meets the firmware size requirements before finalizing the component choice.

Part Context

This component belongs to the ATtiny85 family of 8-bit microcontrollers manufactured by Microchip Technology. It shares architectural similarities with the ATtiny25 and ATtiny45, primarily differing in flash memory capacity. The series is designed for cost-sensitive applications demanding efficient code execution and minimal peripheral overhead.

Replacement Considerations

ATtiny85V-10MU serves as a direct pin-compatible alternative in the same package type but without the tape and reel suffix. Non-V variants such as ATtiny85-20MUR offer higher speed grades but operate at elevated minimum voltage thresholds.
