ATTINY13-20SSQ

Overview

The ATTINY13-20SSQ is an 8-bit AVR microcontroller manufactured by Microchip Technology. It features a high-performance, low-power architecture with up to 20 MIPS throughput at 20 MHz. The device includes 1 KByte of In-System Programmable Flash, 64 Bytes EEPROM, and 64 Bytes Internal SRAM. It operates within a voltage range of 2.7 V to 5.5 V and supports industrial temperature ranges. Key peripherals include a 4-channel 10-bit ADC, an 8-bit Timer/Counter with PWM, and an on-chip analog comparator.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for efficient processing.
• Integrated non-volatile memory segments including self-programmable Flash and EEPROM with data retention capabilities.
• On-chip debug system (debugWIRE) and in-system programming via SPI port for development flexibility.
• Multiple power-saving modes including Idle, ADC Noise Reduction, and Power-down to optimize energy consumption.

Applications

• Embedded control systems requiring low power consumption
• Battery-operated devices utilizing picoPower technology
• Simple sensor interfaces using the integrated ADC
• Basic automation tasks with timer and PWM outputs

Procurement Notes

Verify the specific ordering suffix 'SQ' against official Microchip documentation, as standard datasheets list 'SSU' or 'SSUR' for SOIC packages. Confirm package dimensions and lead finish specifications directly from the manufacturer's latest drawing. Ensure compatibility with existing PCB footprints for the 8-lead SOIC variant. Check for any end-of-life notices or recommended replacements if sourcing for new designs.

Selection Notes

Select this component when a compact 8-bit solution with minimal I/O is required. Consider the ATtiny13V series if operation below 2.7 V is necessary. Evaluate the trade-off between the 20 MHz speed grade and lower frequency options based on power constraints. Ensure the application does not require external crystal oscillators given the internal calibrated oscillator availability.

Part Context

This device belongs to the ATtiny family of 8-bit AVR microcontrollers produced by Microchip Technology. It shares architectural similarities with other members like the ATtiny13A and ATtiny13V, differing primarily in speed grades and voltage ranges. The series is designed for cost-sensitive applications needing reliable performance in a small footprint.

Replacement Considerations

Direct substitutes include ATTINY13-20SSU and ATTINY13-20SUR for identical electrical characteristics in SOIC packaging. For tape and reel requirements, verify availability of SUR variants. Cross-reference pinouts with ATtiny13A models to ensure functional compatibility.
