ATTINY45V-10SH

Overview

The ATTINY45V-10SH is an 8-bit AVR microcontroller featuring 4KB 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 with clock speeds up to 10MHz at 2.7V–5.5V or 4MHz at 1.8V–5.5V. The device includes a 10-bit ADC with four single-ended channels, two PWM outputs, and six programmable I/O lines. It utilizes an enhanced RISC architecture for efficient processing and supports industrial temperature ranges.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• Non-volatile memory with high endurance for program and data storage
• Integrated analog-to-digital converter with differential channel support
• Multiple power-saving modes including idle and power-down

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control modules operating in harsh environments
• Sensor interface circuits utilizing the internal ADC
• Simple logic controllers using programmable I/O ports

Procurement Notes

Verify that the ordering suffix 'H' corresponds to the NiPdAu lead finish as specified in the manufacturer's documentation. Confirm the package type matches the required EIAJ SOIC footprint. Ensure the speed grade '10' aligns with the target system's frequency requirements at the intended supply voltage. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this variant when a 1.8V minimum supply voltage is necessary for battery operation. The 10MHz speed grade provides sufficient throughput for basic control tasks while maintaining low power usage. Consider the 8-pin SOIC package for surface mount applications where space is limited. Verify that the 4KB flash capacity meets the firmware size requirements before choosing over smaller or larger memory variants.

Part Context

This component belongs to the ATtiny45/V family, which shares the same core architecture but differs in memory sizes. The 'V' suffix indicates extended voltage operation down to 1.8V compared to standard versions. The 'SH' designation specifies the plastic small outline package with specific lead finishes. It is part of the broader AVR 8-bit microcontroller portfolio designed for cost-sensitive and power-efficient applications.

Replacement Considerations

ATtiny45V-10SU offers the same specifications in a JEDEC SOIC package. ATtiny45V-10PU provides identical functionality in a PDIP through-hole package. ATtiny45V-10XU is available in a TSSOP package for different board layouts. Standard ATtiny45-10SH variants operate only from 2.7V and are not suitable for 1.8V applications.
