ATTINY861V-10MU

Overview

The ATTINY861V-10MU is an 8-bit AVR microcontroller featuring 8K bytes of In-System Programmable Flash, 512 bytes of EEPROM, and 512 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 16 programmable I/O lines, an 11-channel 10-bit ADC, two timers/counters, and a Universal Serial Interface (USI). It is housed in a 32-pad MLF package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• Integrated non-volatile memories including Flash, EEPROM, and SRAM with data retention capabilities.
• Comprehensive peripheral set featuring a 10-bit ADC, analog comparator, and multiple timer/counter units.
• Supports low-power operation through selectable sleep modes such as Idle, Power-Down, and Standby.

Applications

• Battery-powered sensor nodes requiring low active current consumption.
• Industrial control systems utilizing the industrial temperature range.
• General-purpose embedded applications needing in-system programming via SPI.
• Signal processing tasks involving the on-chip analog comparator and ADC.

Procurement Notes

Verify the specific suffix 'MU' corresponds to the MLF package variant when sourcing. Confirm the 'V' designation indicates the extended voltage range capability. Check manufacturer lifecycle status as components may transition to Not Recommended for New Designs. Ensure ESD precautions are observed during handling due to the exposed pad thermal requirement.

Selection Notes

Select this model for designs requiring 8K Flash memory within the ATtinyx61 family. Choose the MLF package for compact surface-mount layouts. Ensure the operating environment stays within the specified -40°C to +85°C range. Verify that the 10 MHz speed grade meets the system timing requirements at the lowest expected supply voltage.

Part Context

This component belongs to the Microchip ATtinyx61 series of 8-bit AVR microcontrollers. It shares architectural similarities with the ATtiny261 and ATtiny461 but offers higher memory capacities. The series is designed for cost-sensitive applications demanding efficient code execution and robust peripheral integration in small form factors.

Replacement Considerations

Direct pin-compatible substitutes include other variants within the ATtinyx61 family, such as the ATtiny461 or ATtiny261, provided memory requirements align. Higher-speed versions like the ATtiny861A may require voltage level adjustments. Always verify package dimensions and electrical specifications before substitution.
