ATTINY45V-10XU

Overview

The ATTINY45V-10XU is an 8-bit AVR microcontroller featuring 4 Kbytes of In-System Programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. It operates within a voltage range of 1.8 to 5.5 V and supports clock frequencies up to 10 MHz at this supply level. The device utilizes a TSSOP-8 package and includes a 10-bit ADC with four single-ended channels, two differential pairs, and a programmable analog comparator.

Feature Summary

• AVR enhanced RISC architecture delivering near 1 MIPS per MHz throughput
• In-system programmable non-volatile memory with high endurance ratings
• Integrated Universal Serial Interface (USI) supporting multiple communication protocols
• Programmable Watchdog Timer and on-chip Analog Comparator for system monitoring

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control applications utilizing the industrial temperature range
• Sensor interfaces leveraging the integrated 10-bit ADC capabilities

Procurement Notes

Verify that the specific ordering suffix corresponds to the required package type and lead finish. Confirm the speed grade matches the intended operating frequency relative to the supply voltage. Ensure compliance with RoHS directives and check for any applicable wafer form availability requirements directly from the manufacturer.

Selection Notes

Select this component when 4 Kbytes of program memory and 256 bytes of data storage are sufficient for the application logic. Consider the TSSOP-8 package constraints regarding board space and thermal dissipation. Evaluate the need for the extended 1.8 V minimum operating voltage compared to standard variants requiring higher voltages.

Part Context

This device belongs to the ATtiny45/V family within the broader AVR microcontroller portfolio. It shares architectural similarities with the ATtiny25 and ATtiny85, differentiated primarily by its specific memory capacities and package options. The 'V' designation indicates support for operation down to 1.8 Volts.

Replacement Considerations

ATtiny45V-10XUR serves as the tape and reel variant of this component. Other members of the ATtiny45/V family may be considered if memory size or pin count requirements differ.
