ATTINY13-20SSQR

Overview

The ATTINY13-20SSQR is an 8-bit AVR microcontroller manufactured by Microchip Technology, formerly Atmel. It features a 20 MHz maximum clock frequency and operates within a voltage range of 2.7V to 5.5V. The device includes 1KB of in-system programmable Flash memory, 64 bytes of SRAM, and 64 bytes of EEPROM. It is housed in an 8-SOIC package with six general-purpose I/O lines. The component supports a 10-bit Analog-to-Digital Converter (ADC) and complies with RoHS standards.

Feature Summary

• AVR enhanced RISC architecture delivering high code efficiency and throughput near 1 MIPS per MHz.
• Integrated picoPower low-power technology supporting idle, ADC noise reduction, and power-down modes.
• On-chip debugging system (DebugWIRE) enabling single-wire programming and debugging via SPI ports.

Applications

• Battery-powered consumer electronics requiring low standby current
• Simple sensor interface nodes utilizing the internal ADC
• Basic control logic for small appliances or toys

Procurement Notes

Verify the specific suffix 'SQR' against the official Microchip datasheet to confirm the exact temperature grade and packaging variant. Confirm availability status as some ATtiny series components may be subject to lifecycle changes. Ensure the ordering part number matches the required lead time and compliance certifications such as RoHS before finalizing procurement.

Selection Notes

Select this component when a compact 8-bit solution with minimal I/O is required. It is suitable for applications needing basic analog input processing via its integrated ADC. Consider the 1KB Flash limit for complex firmware requirements. Verify that the 20MHz speed and 64-byte RAM are sufficient for the intended algorithmic load.

Part Context

This part belongs to the ATtiny family of 8-bit microcontrollers based on the AVR core. It shares architectural similarities with other members like the ATTINY13A but differs in specific package markings and suffix designations. The series is known for balancing performance with low power consumption in a small footprint.

Replacement Considerations

Check for ATTINY13A-20SSQR as a potential functional equivalent within the same package. Verify pin compatibility and software register mapping before substitution. Consult Microchip documentation for any differences in electrical characteristics or recommended operating conditions between variants.
