ATTINY261V-10SU

Overview

The ATTINY261V-10SU is an 8-bit AVR microcontroller featuring a 2 KB In-System Programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. It utilizes the AVR enhanced RISC architecture with 32 general-purpose working registers. The device operates at a maximum frequency of 10 MHz when powered between 2.7 V and 5.5 V. It includes 16 programmable I/O lines, an 11-channel 10-bit ADC, a Universal Serial Interface (USI), and three high-frequency PWM outputs.

Feature Summary

• Executes powerful instructions in a single clock cycle for efficient processing.
• Supports In-System Programming via SPI interface for flexible firmware updates.
• Integrates multiple power-saving modes including Idle, Standby, and Power-Down.
• Features on-chip debug capabilities through the debugWIRE system.

Applications

• Battery-powered embedded systems requiring low active current consumption
• Industrial control applications utilizing the industrial temperature range
• Sensor interfaces leveraging the 11-channel analog-to-digital converter

Procurement Notes

Verify that the suffix 'V' confirms the extended voltage range of 1.8V to 5.5V operation. Confirm the '-10' designation indicates the 10 MHz speed grade. Ensure the 'SU' package code matches the required 20-pin SOIC form factor. Cross-reference the manufacturer part number with official Microchip databases to confirm authenticity and current production status before procurement.

Selection Notes

Select this component when a balance of moderate flash capacity and extensive analog peripherals is required. The 'V' variant is necessary if the design operates below 2.7V. Consider the 20-pin SOIC package for surface-mount assembly constraints. Evaluate the 10 MHz performance limit against the specific timing requirements of the target application logic.

Part Context

This part belongs to the ATtiny261/V family within the tinyAVR series. It shares architectural similarities with the ATtiny461 and ATtiny861, differing primarily in memory sizes. The 'V' suffix denotes devices optimized for lower voltage operation compared to standard variants. This family targets cost-sensitive applications needing robust peripheral integration.

Replacement Considerations

Direct substitutes include other ATtiny261 variants with matching speed grades and packages. Verify pin compatibility when considering upgrades to ATtiny461 or ATtiny861 due to increased memory resources. Ensure replacement parts maintain the same SOIC-20 footprint and electrical characteristics.
