ATTINY261V-10MUR

Overview

The Atmel ATTINY261V-10MUR is an 8-bit microcontroller based on the AVR RISC core, housed in a 32-pin VQFN package. It features 2 kB of Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. The device operates at a maximum clock frequency of 10 MHz with a supply voltage range of 1.8 V to 5.5 V. Key peripherals include one 10-bit ADC with 11 channels, one PWM unit, and communication interfaces such as SPI and I2C.

Feature Summary

• AVR high-performance RISC architecture enabling efficient code execution
• Integrated analog-to-digital conversion with multiple input channels
• Support for serial peripheral interface and two-wire serial communications

Applications

• Battery-powered embedded systems requiring low power consumption
• Sensor interface circuits utilizing internal ADC capabilities
• General-purpose control applications within industrial or consumer electronics

Procurement Notes

Verify the specific suffix 'MUR' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 32-VQFN form factor. Cross-reference electrical specifications with current datasheets to validate operational limits for your design environment.

Selection Notes

Select this component when a balance of moderate program memory and analog input channels is required in a compact surface-mount package. Consider the 10 MHz speed limit and 1.8 V minimum operating voltage for power-constrained designs. Evaluate alternative pin counts if more general-purpose I/O lines are necessary for the target application.

Part Context

This part belongs to the ATtinyx61 family of 8-bit microcontrollers. The series is characterized by its small footprint and integrated analog features. It shares architectural similarities with other AVR devices but offers specific memory and peripheral configurations tailored for cost-sensitive and space-constrained embedded applications.

Replacement Considerations

Check for ATTINY261A variants which may offer updated manufacturing processes or extended temperature ranges. Verify pinout compatibility before substituting with other members of the ATtinyx61 family to ensure functional equivalence.
