ATTINY461V-10PU

Overview

The ATTINY461V-10PU is an 8-bit AVR microcontroller featuring 4KB of In-System Programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. It operates at a maximum frequency of 10MHz with a supply voltage range of 1.8V to 5.5V. The device includes an 11-channel 10-bit ADC, an analog comparator, and multiple timer/counters. It utilizes a 20-pin PDIP package and supports advanced RISC architecture for efficient single-cycle instruction execution.

Feature Summary

• Advanced RISC architecture delivering high throughput with most instructions executing in a single clock cycle
• Non-volatile memory segments offering high endurance for both program and data storage
• Integrated peripheral set including multi-channel ADC and programmable watchdog timer
• Low-power CMOS technology supporting various power-saving operational modes

Applications

• Battery-powered embedded systems requiring extended operational life
• Industrial control applications utilizing analog signal processing
• Consumer electronics devices needing compact microcontroller solutions
• Smart sensor nodes integrating temperature or voltage monitoring

Procurement Notes

Verify the specific suffix 'V' indicates the wide voltage operation range (1.8V–5.5V) and 'PU' denotes the PDIP package. Confirm RoHS compliance status through official Microchip documentation. Ensure the source provides valid traceability for automotive or industrial grade requirements if applicable. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when design constraints require a balance between processing speed and low power consumption. The 10MHz limit suits applications not demanding high-frequency processing. The 1.8V minimum supply enables operation in battery-centric environments. Consider the 20-pin PDIP form factor for prototyping or through-hole manufacturing needs where surface mount options are unsuitable.

Part Context

This part belongs to the ATtiny461A family, which shares core architectural features but varies in memory size and package options. The 'V' suffix typically specifies the wider voltage operating range compared to standard variants. It serves as a mid-range option within the AVR portfolio, bridging smaller ATtiny models and larger ATmega series devices.

Replacement Considerations

Direct substitutes include other ATtiny461A variants with compatible pinouts. Verify that alternative packages maintain electrical equivalence. Check for updated lifecycle statuses such as NRND recommendations from the manufacturer before finalizing substitution decisions.
