ATTINY261V-10MU

Overview

The Atmel ATTINY261V-10MU is an 8-bit AVR RISC microcontroller featuring a 2 kB Flash program memory, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates at a maximum clock frequency of 10 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes an 11-channel 10-bit ADC, one I2C interface, one SPI channel, and one PWM unit. It is housed in a 32-pin QFN package (5x5 mm) and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates an 11-channel 10-bit analog-to-digital converter for signal acquisition.
• Supports serial communication via dedicated I2C and SPI interfaces.
• Includes hardware peripherals such as a programmable watchdog timer and power-on reset.

Applications

• Battery-powered embedded systems requiring low voltage operation
• Sensor data acquisition nodes utilizing the integrated ADC
• Industrial control modules within standard commercial temperature ranges

Procurement Notes

Verify that the suffix 'V' confirms compliance with RoHS standards and the absence of halogenated flame retardants. Confirm the '-10' designation matches the required 10 MHz operational speed limit for your specific circuit design. Ensure the 'MU' suffix corresponds to the 32-VQFN package type suitable for surface-mount assembly processes.

Selection Notes

Select this component when a compact 32-pin QFN footprint is required alongside 2 kB of non-volatile storage. It is appropriate for designs needing multiple analog inputs via the 11-channel ADC. Consider the 1.8 V minimum supply voltage for compatibility with low-power logic levels.

Part Context

This part belongs to the ATtiny family of 8-bit AVR microcontrollers manufactured by Atmel. It shares architectural similarities with other devices in the series but is distinguished by its specific memory configuration and 32-pin QFN packaging. The product line focuses on providing efficient processing capabilities for resource-constrained applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other ATtiny variants based on pinout and software architecture before substitution.
