ATTINY45V-10MUR

Overview

The ATTINY45V-10MUR is an 8-bit AVR microcontroller featuring 4 KB of In-System Programmable Flash, 256 bytes of EEPROM, and 256 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 six programmable I/O lines, a 10-bit ADC with four single-ended channels, two high-speed PWM outputs, and a Universal Serial Interface (USI). It is housed in an 8-pad QFN/MLF package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for efficient processing.
• Non-volatile memory with high endurance specifications for program flash and EEPROM data retention.
• Integrated peripheral set including timers, counters, analog-to-digital converter, and serial interface.
• Supports multiple low-power operating modes to optimize energy consumption.

Applications

• Battery-powered embedded systems requiring low power consumption
• Simple sensor interfaces utilizing the integrated ADC
• Basic control logic applications using timer and PWM outputs
• Serial communication tasks via the Universal Serial Interface

Procurement Notes

Verify the specific ordering code against official Microchip documentation to ensure correct speed grade, voltage range, and package type. Confirm that the 'R' suffix indicates tape and reel packaging as specified in the datasheet. Check for any applicable RoHS compliance certifications and lead finish details before procurement.

Selection Notes

Select this component when a compact 8-pin solution is required for 4 KB Flash capacity applications. Ensure the design supports the 1.8 V minimum supply voltage for optimal performance at 10 MHz. Consider the QFN package thermal requirements and soldering constraints during PCB layout.

Part Context

This part belongs to the ATtiny45/V family within the AVR 8-bit microcontroller portfolio. It shares architectural similarities with the ATtiny25 and ATtiny85 but offers a specific balance of memory size and pin count suitable for cost-sensitive, space-constrained designs.

Replacement Considerations

Compatible substitutes include ATTINY45V-10MU and ATTINY45V-10XUR from the same manufacturer, provided they match the required package and speed grade specifications.
