ATTINY24-15MZ

Overview

The ATTINY24-15MZ is an automotive-grade 8-bit AVR microcontroller featuring a high-performance RISC core. It integrates 2 Kbytes of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device supports a maximum clock frequency of 16 MHz at 4.5–5.5 V and operates within a voltage range of 2.7 to 5.5 V. It includes twelve programmable I/O lines, a 10-bit ADC with differential channels, two Timer/Counters, and debugWIRE support. Qualified to AEC-Q100 standards, it functions reliably across the full automotive temperature range of -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability
• High-performance single-cycle execution RISC architecture
• Integrated non-volatile memory with programming lock security
• Comprehensive analog peripherals including differential ADC and comparator

Applications

• Automotive electronic control units
• Sensor interface modules
• Low-power embedded systems requiring extended temperature operation

Procurement Notes

Verify the specific suffix 'Z' confirms the -40°C to +125°C automotive temperature grade. Confirm package type matches QFN/MLF requirements. Ensure supply chain sources provide valid AEC-Q100 certification documentation. Cross-reference ordering codes with official Microchip databases to prevent substitution errors.

Selection Notes

Select this component when automotive environmental resilience is mandatory. The 16 MHz speed grade suits applications needing efficient processing at higher voltages. Consider the 12 I/O count and ADC resolution for sensor-heavy designs. Evaluate power consumption against idle and power-down mode specifications for battery-operated constraints.

Part Context

This part belongs to the ATtiny24/44/84 family of 8-bit AVR microcontrollers. It shares architectural similarities with other devices in the series but is distinguished by its automotive qualification and specific memory configuration. The family utilizes a unified Harvard architecture for optimized code efficiency and throughput.

Replacement Considerations

Consult official Microchip documentation for verified cross-references. Substitutions must match the automotive temperature grade and AEC-Q100 qualification status. Verify pin compatibility and memory sizes before implementation.
