ATTINY85-15MT

Overview

The ATTINY85-15MT is an 8-bit AVR microcontroller manufactured by Microchip Technology. It features 8 KB of in-system programmable Flash memory, 512 bytes of EEPROM, and 512 bytes of SRAM. The device operates with a maximum clock frequency of 15 MHz and supports a supply voltage range from 1.8 V to 5.5 V. It includes a 10-bit Analog-to-Digital Converter (ADC) and provides 6 general-purpose I/O pins. The component is housed in a TSSOP-8 surface-mount package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates 8 KB of non-volatile Flash program memory with support for in-system programming via SPI interface.
• Includes 512 bytes of data RAM and 512 bytes of electrically erasable programmable read-only memory for persistent data storage.
• Features a 10-bit analog-to-digital converter with multiple input channels for signal acquisition.
• Supports low-power operation through various sleep modes and dynamic clock frequency adjustment capabilities.

Applications

• Battery-powered sensor nodes requiring minimal power consumption
• Simple control loops in consumer electronics
• Low-pin-count interface adapters
• Basic data logging applications

Procurement Notes

Verify the specific suffix 'MT' against the official Microchip datasheet to confirm the TSSOP-8 package type and industrial temperature grade. Ensure that the ordering information matches the exact speed grade of 15 MHz at the required operating voltage. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required for your assembly process.

Selection Notes

Select this component when a balance between code capacity and pin count is required for compact designs. The 15 MHz speed grade offers higher performance than lower-speed variants while maintaining compatibility with standard AVR development tools. Consider the TSSOP-8 package for automated surface-mount assembly processes where space constraints limit the use of larger packages like SOIC or DIP.

Part Context

This device belongs to the ATtiny85 family of 8-bit AVR microcontrollers, designed for cost-sensitive and space-constrained embedded applications. It shares architectural similarities with other members of the ATtiny series but distinguishes itself through its specific memory configuration and package options. The family is widely used in industries requiring reliable, low-power control solutions with minimal external component requirements.

Replacement Considerations

Compatible substitutes include ATTINY85-20MU for higher speed in a different package, ATTINY85V-10SU for lower voltage operation in SOIC-8, and ATTINY85-10MMU for QFN packaging. Verify pinout compatibility and software register settings before swapping to ensure functional equivalence in the target design.
