ATTINY45V-10SHR

Overview

The ATTINY45V-10SHR is an 8-bit AVR microcontroller featuring a 4 kB In-System Programmable Flash memory, 256 bytes EEPROM, and 256 bytes SRAM. It operates within a voltage range of 1.8 V to 5.5 V at frequencies up to 10 MHz. The device includes a 10-bit ADC with four single-ended channels, two PWM units, and a Universal Serial Interface. It utilizes an 8-pin EIAJ SOIC package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• Non-volatile program and data memories with high endurance ratings
• Integrated peripheral features including timers, counters, and analog-to-digital conversion
• Support for multiple low-power operating modes

Applications

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

Procurement Notes

Verify that the ordering suffix SHR corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm the speed grade matches the operational frequency requirements relative to the supply voltage. Ensure the component meets RoHS compliance standards if mandated by the manufacturing environment.

Selection Notes

Select this variant when a compact surface-mount package is necessary alongside extended low-voltage operation capabilities down to 1.8 V. Consider the available I/O lines and peripheral count against application complexity. Evaluate the trade-off between processing throughput and power consumption inherent to the AVR architecture.

Part Context

This component belongs to the ATtiny45 family within the broader AVR microcontroller portfolio. It shares architectural similarities with the ATtiny25 and ATtiny85, differing primarily in memory capacities. The 'V' designation indicates support for lower supply voltages compared to standard variants.
