Overview
The ATTINY461V-10SUR is an 8-bit AVR microcontroller featuring 4K bytes of In-System Programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. It operates within a voltage range of 1.8V to 5.5V and supports clock frequencies up to 10MHz at the higher voltage range. The device includes 16 programmable I/O lines, an 11-channel 10-bit ADC, and a Universal Serial Interface.
Feature Summary
- Advanced RISC architecture with single-cycle execution for high throughput
- Non-volatile memory with high endurance for program and data storage
- Integrated analog-to-digital converter with multiple channel options
- Multiple power-saving modes including idle and power-down
Applications
- Low-power embedded control systems
- Sensor interface applications requiring ADC conversion
- Industrial monitoring devices operating in wide temperature ranges
- Battery-powered portable electronics
Procurement Notes
Verify the specific suffix 'V' indicates the extended voltage range (1.8V minimum) and '10' denotes the 10MHz speed grade. Confirm the 'SUR' suffix corresponds to the SOIC-20 tape and reel packaging format. Ensure compatibility with existing SPI programming interfaces for in-system flashing.
Selection Notes
Select this variant when operation below 2.7V is required, as standard ATtiny461 models do not support 1.8V. Compare pin counts and peripheral sets against ATtiny261 or ATtiny861 if different memory sizes are needed. Verify that the 10MHz speed rating meets the timing requirements of the target application at the intended supply voltage.
Part Context
This component belongs to the ATtinyx61 family of 8-bit AVR microcontrollers. It shares architectural similarities with the ATtiny261 and ATtiny861, differing primarily in memory capacities. The V-series variants are distinguished by their ability to operate at lower supply voltages compared to the non-V counterparts.
