ATTINY24-15SSZ

Overview

The ATtiny24-15SSZ is an automotive-grade, low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It features 2K bytes of in-system programmable Flash memory with 10,000 write/erase cycle endurance and 128 bytes of EEPROM with 100,000 write/erase cycle endurance. The device includes 128 bytes of internal SRAM and twelve general-purpose I/O lines. Operating voltage ranges from 2.7V to 5.5V, supporting speeds up to 8MHz at 2.7-5.5V and 16MHz at 4.5-5.5V. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Automotive quality grade compliant with ISO-TS-16949 and AEC-Q100 standards for extended temperature operation.
• Advanced RISC architecture achieving throughput approaching 1MIPS per MHz via single-clock-cycle execution.
• Integrated analog peripherals including an 8-channel 10-bit ADC with programmable gain and an on-chip analog comparator.
• Comprehensive timer subsystem featuring two Timer/Counters with multiple PWM channels and a programmable watchdog timer.

Applications

• Cost-sensitive sensor applications requiring automotive reliability
• Real-time control systems operating in harsh environments
• Low power embedded devices utilizing sleep modes

Procurement Notes

Verify that the specific ordering suffix corresponds to the SOIC-14 package and the -15 speed grade (16MHz max). Confirm the 'Z' identifier denotes the full automotive temperature range (-40°C to +125°C) as specified in the datasheet's temperature grade identification table. Ensure compatibility with the required supply voltage range of 2.7V to 5.5V for the target application design.

Selection Notes

Select this component when automotive qualification under AEC-Q100 is mandatory for the project. It is suitable for designs needing 2KB of program memory and 128 bytes of data storage in a compact 14-pin package. Consider the 16MHz maximum frequency capability if higher processing speed is required at voltages above 4.5V. Evaluate the 12 available I/O lines against the pin count requirements of the peripheral interface.

Part Context

This device belongs to the ATtiny24/44/84 family of 8-bit AVR microcontrollers. The family shares a common core architecture but varies in memory sizes and pin counts. The ATtiny24 represents the entry-level variant with 2KB Flash, offering a balance of performance and cost for constrained automotive and industrial applications.

Replacement Considerations

Cross-reference with other members of the ATtiny24/44/84 family for memory or pin count adjustments. Verify pinout compatibility if substituting with non-Automotive grade variants, noting potential differences in temperature range specifications.
