ATTINY461V-10MUR

Overview

The Atmel ATTINY461V-10MUR is an 8-bit microcontroller based on the AVR RISC architecture, featuring 4 kB of In-System Programmable Flash memory. It includes 256 bytes of EEPROM and 256 bytes of internal SRAM. The device supports a maximum clock frequency of 10 MHz and operates within a supply voltage range of 1.8 V to 5.5 V. It utilizes a WQFN-20 surface-mount package and provides 16 programmable I/O lines.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput
• Non-volatile memory segments with high endurance specifications for program and data storage
• Integrated 10-bit analog-to-digital converter with multiple channel options
• On-chip analog comparator and programmable watchdog timer

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control applications utilizing analog signal processing
• General-purpose microcontroller tasks in compact surface-mount designs

Procurement Notes

Verify the specific suffix 'V' indicates the extended temperature range variant and 'MUR' denotes the WQFN-20 tape and reel packaging configuration. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure compatibility with existing SPI programming interfaces for firmware updates.

Selection Notes

Select this model when 4 kB of flash memory and 256 bytes of RAM are sufficient for application logic. The 10 MHz speed rating suits moderate processing requirements. Consider the WQFN-20 package for space-constrained PCB layouts compared to larger SOIC or PDIP alternatives.

Part Context

This component belongs to the ATtinyx61A family of 8-bit microcontrollers. It shares architectural similarities with the ATtiny261A and ATtiny861A, differing primarily in memory capacities. The family is designed for cost-sensitive applications needing efficient code execution and peripheral integration.

Replacement Considerations

Public confirmed substitute part numbers include ATTINY461A-SU and ATTINY461A-MU. Verify pinout compatibility and electrical characteristics before substitution.
