ATTINY261V-10PU

Overview

The ATTINY261V-10PU is an 8-bit AVR RISC microcontroller featuring a 10 MHz operating speed. It integrates 2 KB of Flash program memory, 128 bytes of EEPROM, and 128 bytes of SRAM. The device operates within a voltage range of 1.8 V to 5.5 V and supports a temperature range of -40°C to +85°C. Key peripherals include an 11-channel 10-bit ADC, USI interface, PWM, and hardware reset sources such as brown-out detect and power-on reset. It is housed in a 20-pin DIP package.

Feature Summary

• Integrates an 8-bit AVR RISC CPU with non-volatile memory for code storage and data retention.
• Includes an analog-to-digital converter with multiple channels for sensor interfacing.
• Provides universal serial interface (USI) for simplified communication protocols.
• Features internal oscillators and reset mechanisms for stable system operation.

Applications

• Battery-powered embedded systems requiring low voltage operation
• Simple sensor monitoring applications utilizing the ADC
• Basic control loops using PWM outputs
• Systems requiring minimal I/O count with serial communication via USI

Procurement Notes

Verify the specific suffix 'V' indicates the wide voltage range variant and '10' denotes the 10 MHz frequency rating. Confirm the 'PU' suffix corresponds to the 20-pin PDIP package. Check manufacturer documentation for current production status, as this part may be obsolete or superseded by newer revisions within the ATtiny family. Ensure compatibility with your programming interface before procurement.

Selection Notes

Select this component when an 8-bit AVR architecture is required with integrated EEPROM and ADC capabilities. It is suitable for applications needing a balance of processing power and peripheral integration in a small form factor. Consider the 1.8 V minimum supply voltage for battery-operated designs. Evaluate if the USI interface meets your communication needs instead of dedicated SPI or USART modules found in larger devices.

Part Context

This part belongs to the ATtiny261/461/861 family of 8-bit AVR microcontrollers. These devices share a common core architecture and instruction set, allowing for pin-compatible upgrades within the series based on memory size requirements. The ATTINY261 represents the entry-level option in this group with 2 KB of Flash memory.

Replacement Considerations

Check for direct replacements like ATTINY261A-10SU or ATTINY261A-10MU which offer updated manufacturing processes. Verify if the 'A' suffix variant maintains identical electrical characteristics and pinout compatibility for your existing design.
