ATTINY861V-10MUR

Overview

The ATtiny861V-10MUR is an 8-bit AVR microcontroller featuring 8 KB of in-system programmable Flash memory, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates within a voltage range of 1.8 V to 5.5 V and supports clock frequencies up to 10 MHz. The device utilizes a 32-pin VQFN package with exposed pad.

Feature Summary

• AVR RISC core architecture for efficient instruction execution
• In-system programmable non-volatile memory systems
• Low power consumption operation across wide voltage ranges

Applications

• Battery-powered embedded control systems
• General-purpose digital logic interfacing
• Sensor data acquisition nodes

Procurement Notes

Verify the specific suffix 'V' indicates extended temperature or voltage variants per official datasheets. Confirm the 'MUR' suffix corresponds to the 32-pin VQFN tape and reel packaging configuration. Check current lifecycle status as some distributors list this part as Not Recommended for New Designs (NRND). Ensure RoHS compliance documentation matches the manufacturing date code.

Selection Notes

Select this component when 8 KB program memory and 512 bytes each of RAM and EEPROM are required in a compact surface-mount form factor. The 10 MHz speed rating suits applications where moderate processing performance is needed without high-frequency noise concerns. Compare against the ATTINY861A series if higher 20 MHz clock speeds are necessary for the application.

Part Context

This part belongs to the ATtinyx61 family of 8-bit microcontrollers from Microchip Technology (formerly Atmel). These devices are designed for cost-sensitive applications requiring reliable AVR architecture. The VQFN package provides thermal dissipation through an exposed pad, suitable for dense PCB layouts.

Replacement Considerations

ATTINY861A-MUR offers similar specifications but supports up to 20 MHz clock speeds. Verify pin compatibility and software register differences before substitution.
