ATTINY45-15ST1

Overview

The ATTINY45-15ST1 is an 8-bit AVR microcontroller featuring a 4 KB in-system programmable Flash memory, 256 bytes of EEPROM, and 256 bytes of SRAM. It operates with a maximum clock frequency of 15 MHz and supports a supply voltage range from 2.7 V to 5.5 V. The device includes a 10-bit ADC, six general-purpose I/O lines, and is housed in an 8-pin SOIC package.

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.
• Integrates on-chip analog-to-digital conversion capabilities for sensor interfacing.

Applications

• Battery-powered embedded systems requiring low power consumption
• Simple control loops in consumer electronics
• Basic data acquisition tasks using internal ADC

Procurement Notes

Verify the specific suffix ST1 against official Microchip documentation to confirm the package type and temperature grade. Ensure compatibility with your PCB footprint and operating environment specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact 8-pin solution is required for basic logic control or simple analog monitoring. Consider the 4 KB Flash limit for larger applications and verify that the 15 MHz speed meets real-time processing requirements.

Part Context

This part belongs to the ATtiny45/25/45 family of 8-bit microcontrollers. These devices are designed for cost-sensitive applications where small form factors and minimal peripheral counts are prioritized over complex processing capabilities.

Replacement Considerations

Check for ATTINY45-15SU or ATTINY45-10SU if different package styles or speed grades are needed. Verify pinout compatibility and electrical characteristics before substituting with other AVR series components.
