ATTINY45V-15ST

Overview

The ATTINY45V-15ST is an 8-bit AVR microcontroller manufactured by Microchip Technology. It features a core operating frequency of up to 15 MHz and includes 4 KB of in-system programmable Flash memory, 256 bytes of EEPROM, and 512 bytes of SRAM. The device operates within a supply voltage range of 2.7 V to 5.5 V and provides six general-purpose I/O lines. It integrates an 8-channel, 10-bit ADC and supports multiple communication interfaces including SPI and TWI.

Feature Summary

• Incorporates the high-performance, low-power AVR 8-bit CPU architecture for efficient code execution.
• Provides non-volatile program storage via in-system programmable Flash technology.
• Includes on-chip analog-to-digital conversion capabilities with selectable reference voltages.
• Supports serial programming and debugWIRE interface for development and maintenance.

Applications

• Battery-powered consumer electronics requiring low standby current
• Simple sensor nodes utilizing internal ADC for data acquisition
• Basic control logic in home appliances and small instruments

Procurement Notes

Verify the specific suffix 'ST' against the official Microchip datasheet to confirm package type and temperature grade. Ensure the ordered component matches the required voltage range and clock speed specifications for your target application environment before finalizing procurement.

Selection Notes

Select this model when a compact 8-bit solution with moderate Flash capacity is needed. Compare against the ATTINY45 series for standard performance or the ATTINY45V series if lower voltage operation is critical. Evaluate pin count and peripheral requirements against larger AVR variants if more I/O is necessary.

Part Context

This component belongs to the Microchip AVR ATtiny family, designed for cost-sensitive embedded applications. It shares architectural similarities with other ATtiny devices but offers specific memory and speed configurations tailored for simple control tasks. The 'V' suffix typically denotes extended voltage ranges.

Replacement Considerations

Direct substitutes include other ATtiny45 variants such as ATTINY45-20SU or ATTINY45-10PU, depending on package and speed requirements. Cross-reference with ATTINY25 or ATTINY85 if memory constraints differ. Verify pin compatibility and firmware compatibility before substitution.
