ATTINY861V-10SUR

Overview

The ATTINY861V-10SUR is an 8-bit AVR microcontroller featuring 8K bytes 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 and supports clock frequencies up to 10MHz at the higher voltage range. The device utilizes a VQFN-32 package and includes an 11-channel 10-bit ADC, a Universal Serial Interface, and multiple timer/counters.

Feature Summary

• High-performance 8-bit AVR architecture with single-cycle execution for efficient processing
• Non-volatile memory with high endurance for program and data storage
• Integrated analog-to-digital converter with differential channel support
• Multiple low-power operating modes including Idle and Power-Down

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control applications utilizing programmable timers and PWM
• Sensor interfaces leveraging the high-resolution ADC channels
• General-purpose logic control using SPI and I2C communication interfaces

Procurement Notes

Verify the specific suffix 'SUR' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 'V' designation indicates the extended voltage range compatible with your system's power supply specifications. Ensure the component meets RoHS compliance standards if mandated by your manufacturing regulations.

Selection Notes

Select this variant when 8KB of program memory is necessary for complex firmware implementations. Choose the V-grade version if operation below 2.7V is required, as standard variants may not function correctly at lower voltages. Consider the VQFN-32 package dimensions against available PCB real estate constraints during the layout phase.

Part Context

This component belongs to the ATtinyX61 family of microcontrollers manufactured by Microchip Technology. It shares architectural similarities with the ATtiny461 and ATtiny261 but offers increased memory capacity. The series is designed for cost-sensitive applications demanding robust performance in a compact form factor.

Replacement Considerations

Direct substitutes include the ATTINY861V-10PU or ATTINY861V-10SU depending on the preferred package type. Verify pin compatibility and memory specifications before swapping between different package styles to ensure mechanical fit.
