ATTINY13A-SSU

Overview

The ATTINY13A-SSU is an 8-bit AVR microcontroller from Microchip Technology, housed in an 8-SOIC package. It features a high-performance RISC architecture delivering up to 20 MIPS at 20 MHz. The device includes 1 KB of In-System Programmable Flash, 64 bytes of EEPROM, and 64 bytes of SRAM. Operating voltage ranges from 1.8V to 5.5V with industrial temperature support (-40°C to +85°C). Key peripherals include a 4-channel 10-bit ADC, an 8-bit Timer/Counter with PWM, an analog comparator, and debugWIRE debugging.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for optimized power-speed performance.
• Integrated non-volatile memory segments including self-programmable Flash, EEPROM, and SRAM with data retention specifications.
• Comprehensive peripheral set featuring a 10-bit ADC, 8-bit Timer/Counter with PWM channels, and on-chip analog comparator.
• Supports low-power operation through Idle, ADC Noise Reduction, and Power-down modes with programmable brown-out detection.

Applications

• Battery-powered consumer electronics requiring low active current consumption.
• Simple sensor interfaces utilizing the integrated 10-bit ADC.
• Basic motor or lighting control applications using PWM outputs.
• Cost-sensitive embedded systems needing in-system programming via SPI.

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the 'SSU' designation corresponds to the 8-SOIC variant with the specified industrial temperature range. Ensure compatibility with existing PCB footprints and reflow profiles for SOIC packages. Check for any recent product change notices regarding marking or assembly sites.

Selection Notes

Select this component when a compact 8-bit solution with integrated ADC and PWM is required. The 8-SOIC package suits surface-mount designs with moderate pin count needs. Consider the speed grades relative to supply voltage; higher frequencies require higher voltages. Evaluate memory requirements against the 1KB Flash limit before choosing alternative ATtiny variants.

Part Context

This part belongs to the ATtiny13A family, which shares core architectural features across different packages such as PDIP and VDFN. The SSU suffix specifically identifies the 8-pin Small Outline Integrated Circuit (SOIC) version. It is designed for applications where space and power efficiency are critical constraints within the broader AVR microcontroller ecosystem.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other ATtiny13A variants with different suffixes indicating package or temperature changes. Cross-family migration to larger ATtiny devices requires schematic and firmware modifications due to pin and peripheral differences.
