ATTINY13A-SS7

Overview

The ATTINY13A-SS7 is an 8-bit AVR microcontroller from Microchip Technology, utilizing the enhanced RISC architecture. It features 1K bytes of In-System Programmable Flash, 64 bytes EEPROM, and 64 bytes SRAM. The device operates within a voltage range of 1.8V to 5.5V and supports clock speeds up to 20MHz depending on supply voltage. It includes six programmable I/O lines, a 4-channel 10-bit ADC, an analog comparator, and an 8-bit Timer/Counter with PWM capabilities. The component is housed in an 8-pin SOIC package.

Feature Summary

• Advanced RISC architecture enabling single-clock-cycle instruction execution for high throughput.
• Integrated non-volatile memory segments including self-programmable Flash, EEPROM, and SRAM.
• On-chip debug system (debugWIRE) and SPI-based in-system programming support.
• Multiple low-power sleep modes including Idle, Power-down, and ADC Noise Reduction.

Applications

• Battery-powered embedded systems requiring low power consumption
• Simple sensor interfaces utilizing the internal ADC
• Basic control logic using timer and PWM outputs
• Cost-sensitive consumer electronics

Procurement Notes

Verify the specific suffix 'SS7' against official Microchip documentation to confirm package dimensions and tape-and-reel specifications, as standard datasheets often list 'SSU' or 'SSH'. Ensure the ordering code matches the required industrial temperature range and RoHS compliance status. Cross-reference the part number with the manufacturer's current production status to confirm availability.

Selection Notes

Select this component for applications needing a compact 8-bit solution with minimal peripheral requirements. The wide operating voltage range allows flexibility in power supply design. Consider the limited pin count when designing PCB layouts. Verify that the 1KB program memory is sufficient for the intended firmware complexity before finalizing the design.

Part Context

This part belongs to the ATtiny13A family, which are low-power CMOS 8-bit microcontrollers based on the AVR core. The series is designed for applications where code size and power consumption are critical constraints. The ATtiny13A variant specifically offers improved endurance and reliability features compared to earlier generations, maintaining compatibility with existing development tools.

Replacement Considerations

Direct replacements include ATTINY13A-SSU and ATTINY13A-SSH, which share identical electrical characteristics and pinouts but may differ in packaging quantity or specific reel configurations. Ensure any substitute maintains the same 8-SOIC footprint and voltage ratings.
