ATTINY461V-10SU

Overview

The ATTINY461V-10SU is an 8-bit AVR microcontroller featuring 4K bytes of In-System Programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. It operates within a voltage range of 1.8V to 5.5V and supports clock frequencies up to 10MHz at this supply level. The device includes 16 programmable I/O lines, an 11-channel 10-bit ADC, and a Universal Serial Interface. It utilizes a 20-pin SOIC package and functions across the industrial temperature range of -40°C to +85°C.

Feature Summary

• Advanced RISC architecture with single-cycle instruction execution
• Non-volatile memory with high endurance for program and data storage
• Integrated analog-to-digital converter with multiple channel options
• Multiple low-power sleep modes for energy optimization

Applications

• Battery-powered embedded systems requiring extended operational life
• Industrial control applications operating in wide temperature environments
• Sensor interface circuits utilizing the on-chip ADC capabilities
• General-purpose logic control using programmable I/O ports

Procurement Notes

Verify that the specific part number suffix matches the required speed grade and package type. Confirm the manufacturing source aligns with project quality standards. Ensure the component meets RoHS compliance requirements for the intended market. Check for any specific handling instructions related to the surface-mount packaging during assembly processes.

Selection Notes

Select this variant when operation below 2.7V is necessary, as standard ATtiny461 models do not support voltages down to 1.8V. The 'V' suffix indicates the lower voltage capability essential for battery-operated designs. The '10' suffix specifies the maximum frequency rating suitable for moderate processing speeds. Consider the SOIC package for standard PCB layout compatibility.

Part Context

This component belongs to the ATtiny461 family of 8-bit AVR microcontrollers. It shares architectural similarities with the ATtiny261 and ATtiny861, differing primarily in memory capacity. The V-series variants are distinguished by their ability to operate at lower supply voltages compared to non-V counterparts. This specific model represents a mature device within the Microchip portfolio.

Replacement Considerations
