ATTINY85-15MZ

Overview

The ATTINY85-15MZ is an 8-bit microcontroller from the ATtiny family, featuring 8 KB of in-system programmable Flash memory, 512 bytes of SRAM, and 512 bytes of EEPROM. It operates with a maximum clock frequency of 15 MHz and supports a supply voltage range of 1.8 V to 5.5 V. The device utilizes a 8-pin MSOP package and incorporates an AVR CPU with hardware multiplier. Key peripherals include a 10-bit ADC with four single-ended channels, two 8-bit timers/counters with PWM outputs, and a Universal Serial Interface (USI).

Feature Summary

• Incorporates an advanced RISC architecture with 121 powerful instructions, most executing in a single clock cycle.
• Features non-volatile memory with high endurance specifications for both program Flash and data EEPROM.
• Includes integrated peripheral modules such as a 10-bit analog-to-digital converter and programmable watchdog timer.
• Supports low-power operation modes including idle, ADC noise reduction, and power-down.

Applications

• Embedded control systems requiring compact form factors
• Battery-powered devices due to low power consumption capabilities
• Simple sensor interface applications utilizing ADC features
• Consumer electronics with limited pin count requirements

Procurement Notes

Verify that the specific suffix 'MZ' corresponds to the MSOP package type and industrial temperature range as defined in the official Microchip datasheet. Confirm that the ordering information matches the exact part number designation to ensure correct package and performance grade acquisition. Cross-reference the manufacturer's latest documentation for any updates to pinout or electrical characteristics prior to procurement.

Selection Notes

Select this component when an 8-bit AVR core is required with 8 KB of program memory and a 15 MHz operating speed. The choice is appropriate for designs constrained by an 8-pin MSOP footprint. Consider the 1.8 V minimum supply voltage for battery-operated applications. Ensure the design utilizes the available USI and ADC resources effectively within the limited pin availability.

Part Context

This part belongs to the ATtiny series of 8-bit microcontrollers manufactured by Microchip Technology. It shares the core architecture with variants like the ATtiny45 and ATtiny25 but offers higher memory capacity. The series is designed for cost-sensitive embedded applications where small size and energy efficiency are critical priorities.

Replacement Considerations

Public confirmed substitute part numbers include ATTINY85-20MU and ATTINY85-20SU. These alternatives offer the same functional specifications but differ in maximum clock frequency and package type. Verify package compatibility and speed requirements before substitution.
