ATTINY45V-10PU

Overview

The ATTINY45V-10PU is an 8-bit AVR microcontroller from Microchip Technology, based on the ATtiny series. It features a 10 MHz maximum clock frequency and operates within a 1.8V to 5.5V voltage range. The device includes 4KB of in-system programmable Flash memory, 256 bytes of EEPROM, and 256 bytes of SRAM. It utilizes a PDIP-8 package with through-hole mounting. Key peripherals include a 4-channel 10-bit ADC, two PWM channels, and USI communication interfaces.

Feature Summary

• AVR enhanced RISC architecture for efficient single-cycle instruction execution
• Non-volatile memory with high endurance for program and data storage
• Integrated analog-to-digital converter with multiple channel options
• Supports in-system programming via SPI interface

Applications

• Battery-powered consumer electronics requiring low power consumption
• Simple sensor interfacing and data acquisition systems
• Basic control logic in industrial automation components
• Educational prototyping platforms for embedded systems

Procurement Notes

Verify the manufacturer marking matches Microchip or Atmel specifications. Confirm the suffix 'V' indicates extended voltage ranges and '-10' denotes the 10 MHz speed grade. Ensure the 'PU' suffix corresponds to the PDIP-8 package type. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the component is new and free from physical damage before integration.

Selection Notes

Select this model when 4KB of Flash memory is sufficient for application code. Choose it over smaller variants like ATtiny25 if additional program space is needed. Opt for the PDIP-8 package if through-hole assembly is preferred over surface mount alternatives. Consider the 1.8V minimum operating voltage for battery-powered designs requiring wider supply flexibility than lower-voltage-only devices.

Part Context

This component belongs to the ATtiny family of 8-bit AVR microcontrollers. It shares architectural similarities with the ATtiny25 and ATtiny85, differing primarily in memory capacity. The series is known for picoPower technology, enabling operation at low frequencies and voltages. It serves as a cost-effective solution for applications requiring moderate processing power with minimal external components.

Replacement Considerations

Direct substitutes include ATtiny45V-10AU (surface mount) and ATtiny45V-10MU (miniature flat package). Cross-series replacements like ATtiny25V-10PU offer reduced memory but maintain pin compatibility. Verify that any replacement maintains the same PDIP-8 footprint and electrical characteristics for seamless integration.
