ATTINY13A-SF

Overview

The ATTINY13A-SF is an 8-bit AVR microcontroller in an 8-pin SOIC package. It features a high-performance, low-power architecture with up to 20 MIPS throughput at 20 MHz. Memory includes 1 KB of In-System Programmable Flash, 64 bytes EEPROM, and 64 bytes SRAM. The device operates on a supply voltage of 1.8 V to 5.5 V and supports industrial temperature ranges. Key peripherals include a 4-channel 10-bit ADC, an analog comparator, and a programmable watchdog timer.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for efficient processing.
• Integrated debugWIRE on-chip debug system enabling single-wire programming and debugging via SPI.
• Multiple software-selectable power-saving modes including Idle, ADC Noise Reduction, and Power-down.
• High endurance non-volatile memory segments with specified write/erase cycles and data retention capabilities.

Applications

• Battery-powered consumer devices requiring low active current consumption
• Simple sensor interfaces utilizing the internal 10-bit ADC
• Basic control logic for appliances using PWM outputs
• Cost-sensitive embedded systems needing in-system reprogrammability

Procurement Notes

Verify the specific suffix SF corresponds to the 8-SOIC package variant when sourcing. Confirm that the required operating frequency aligns with the voltage-speed grades defined in the datasheet. Ensure development tools support the debugWIRE interface for programming. Check for any recent product change notifications regarding packaging or material compliance before finalizing orders.

Selection Notes

Select this component for designs prioritizing minimal pin count and low power consumption over complex communication interfaces. It lacks dedicated UART or I2C hardware, relying on bit-banging if needed. Consider the limited 64-byte SRAM for complex data structures. The internal calibrated oscillator may require external calibration for precise timing applications compared to crystal-driven variants.

Part Context

This part belongs to the Microchip ATtiny family, specifically the ATtiny13A series. These are 8-bit CMOS microcontrollers based on the AVR enhanced RISC architecture. The family is designed for applications requiring small form factors and low cost, offering a balance of performance and power efficiency suitable for simple control tasks.

Replacement Considerations

Direct replacements within the same package must maintain the 8-SOIC footprint and compatible pinout. Verify that substitute parts offer equivalent Flash and SRAM sizes. Ensure the replacement supports the required voltage range and temperature specifications. Check for compatibility with existing debugWIRE programming interfaces.
