ATTINY45-15MT1

Overview

The ATTINY45-15MT1 is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features 4 KB of in-system programmable Flash memory, 256 bytes of EEPROM, and 256 bytes of SRAM. The device operates with a maximum clock frequency of 15 MHz and supports a supply voltage range from 2.7 V to 5.5 V. It includes a 10-bit Analog-to-Digital Converter (ADC) and offers six general-purpose I/O lines. The component is housed in an MLF-8 package and is designed for surface-mount technology applications.

Feature Summary

• Integrates 4 KB of non-volatile Flash memory for program storage and data retention without power.
• Includes dedicated 256-byte EEPROM for persistent data storage independent of the main program memory.
• Features a 10-bit ADC module for converting analog signals into digital values for processing.

Applications

• Battery-powered embedded systems requiring low power consumption
• Simple sensor interface circuits utilizing the internal ADC
• Basic control logic in consumer electronics devices

Procurement Notes

Verify the specific suffix MT1 corresponds to the MLF-8 package and tape-and-reel delivery format when ordering. Confirm that the 15 MHz speed grade matches the system timing requirements. Ensure compatibility with the 2.7 V to 5.5 V operating voltage range for the target application environment.

Selection Notes

Select this component when a compact 8-bit solution with integrated EEPROM and ADC is required. The MLF-8 package suits space-constrained designs. Consider the 15 MHz performance limit against higher-speed alternatives if complex real-time processing is needed. Verify pinout compatibility with existing PCB layouts using the official datasheet.

Part Context

This part belongs to the ATtiny45/25/45 family of 8-bit AVR microcontrollers. These devices are optimized for cost-sensitive and space-limited applications. The family shares common architectural features but varies in memory size and package options. The ATTINY45-15MT1 specifically provides the mid-range memory configuration within this series.

Replacement Considerations

Check for ATTINY45-15MU as a potential alternative in different packaging. Verify electrical specifications and pin compatibility before substituting. Consult Microchip documentation for any obsolescence notices or recommended new parts for this legacy series.
