ATTINY861-15MAZ

Overview

The ATTINY861-15MAZ is an automotive-grade, 8-bit AVR microcontroller featuring 8KB of in-system programmable Flash memory. It operates within a voltage range of 2.7V to 5.5V and supports clock speeds up to 16MHz at the higher voltage range. The device includes 512 bytes of EEPROM and 512 bytes of internal SRAM. It utilizes a 32-pad MLF package with 16 programmable I/O lines and meets AEC-Q100 Grade 1 qualification standards for operation across the full automotive temperature range.

Feature Summary

• Automotive-grade reliability verified through AEC-Q100 Grade 1 qualification and ISO-TS 16949 manufacturing processes.
• High-performance AVR RISC architecture enabling single-clock-cycle execution for efficient power management.
• Integrated non-volatile memories including Flash, EEPROM, and SRAM with specified endurance ratings.
• Comprehensive peripheral set including high-speed timers, PWM outputs, and a multi-channel ADC.

Applications

• Sensorless control of three-phase brushless DC (BLDC) fans
• Automotive electronic modules requiring extended temperature tolerance
• Low-power embedded systems utilizing static operation modes

Procurement Notes

Verify the specific suffix 'MAZ' against official Microchip documentation to confirm the MLF package type and automotive temperature grade. Ensure the ordering information matches the required speed grade and voltage specifications for the target application environment.

Selection Notes

Select this component when automotive qualification and wide operating temperature ranges are mandatory. The 8KB Flash capacity suits applications requiring moderate code storage. Consider the 32-pad MLF package constraints for PCB layout and thermal management requirements during the design phase.

Part Context

This part belongs to the ATtinyx61 family of automotive microcontrollers. It shares architectural similarities with the ATtiny261 and ATtiny461 but offers increased memory capacity. The family is designed for cost-sensitive automotive applications requiring robust performance and low power consumption.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the ATtinyx61 series. Verify that any replacement maintains the same automotive qualification status and package dimensions.
