ATTINY13-20SQ

Overview

The ATTINY13-20SQ is an 8-bit AVR microcontroller manufactured by Microchip Technology, formerly Atmel. It features a 1KB system-in-programmable Flash memory, 64 bytes of EEPROM, and 64 bytes of SRAM. The device operates with a maximum clock frequency of 20 MHz at supply voltages between 4.5V and 5.5V, while supporting operation down to 2.7V at reduced frequencies. It utilizes an enhanced AVR RISC architecture for high throughput. The component is housed in an 8-pin SOIC package and includes six programmable I/O lines.

Feature Summary

• Integrates an 8-bit AVR RISC core with single-cycle instruction execution capability.
• Includes on-chip non-volatile memory consisting of Flash, EEPROM, and SRAM.
• Features a 4-channel 10-bit analog-to-digital converter (ADC).
• Supports in-system programming via the SPI interface.

Applications

• Embedded control systems requiring low pin count
• Battery-powered devices utilizing picoPower technology
• Simple sensor interfaces and monitoring nodes

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature range. Confirm current production status as availability may vary. Ensure compatibility with existing PCB footprints for the 8-SOIC variant. Check for lead-free compliance requirements relevant to your manufacturing process.

Selection Notes

Select this component when a compact 8-bit solution with minimal I/O is required. It is suitable for applications where code size fits within 1KB Flash. Consider the 20MHz speed rating only if operating within the higher voltage range. Evaluate power consumption needs against the available sleep modes for battery efficiency.

Part Context

This part belongs to the ATtiny series of microcontrollers from Microchip Technology. The series is known for combining high performance with low power consumption using the AVR architecture. The ATTINY13 variant specifically targets cost-sensitive and space-constrained embedded applications requiring basic processing capabilities.

Replacement Considerations

Check for ATTINY13-20SSU or ATTINY13-20PU for alternative packages such as TSSOP or PDIP. Verify electrical specifications match before substitution. Ensure pinout compatibility if replacing directly on a board.
