ATTINY44-15MZ

Overview

The ATTINY44-15MZ is an 8-bit AVR microcontroller featuring 4KB of 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 1.8V to 5.5V. The device utilizes a WQFN-20 package and is rated for industrial temperature ranges extending up to 125°C.

Feature Summary

• Advanced RISC architecture enabling most instructions to execute in a single clock cycle
• In-system programmable non-volatile memory with high endurance specifications
• Fully static operation allowing flexible power management across voltage levels

Applications

• Cost-sensitive sensor interface nodes
• Real-time control loops in embedded systems
• Low-power portable devices requiring extended battery life

Procurement Notes

Verify the specific suffix 'MZ' confirms the WQFN-20 package and 15MHz speed grade. Confirm the operating temperature range meets the -40°C to +125C requirement. Ensure the ordering code matches the exact pinout and tape-and-reel packing media specified by Microchip Technology for this variant.

Selection Notes

Select this component when a compact surface-mount solution is required for AVR-based designs. It offers higher thermal tolerance than standard commercial variants. Consider the trade-off between the smaller footprint and the fixed 15MHz performance limit compared to faster counterparts.

Part Context

This part belongs to the ATtiny44 family within the Microchip AVR portfolio. It shares core architectural features with other ATtiny44 variants but differs in package type and speed grading. The MZ suffix specifically denotes the WQFN package and industrial temperature rating.

Replacement Considerations

Direct substitutes include ATTINY44A-15SU or ATTINY44-15PU if package compatibility allows. Verify pin-to-pin equivalence and ensure the replacement maintains the required 125°C operating temperature range.
