ATTINY13A-SFR

Overview

The ATTINY13A-SFR is an 8-bit AVR microcontroller featuring 1KB of In-System Programmable Flash, 64 bytes of EEPROM, and 64 bytes of SRAM. It operates at speeds up to 20 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 4-channel 10-bit ADC, an 8-bit Timer/Counter with PWM, and an on-chip analog comparator. It utilizes an internal calibrated oscillator and supports debugWIRE debugging via SPI.

Feature Summary

• AVR enhanced RISC architecture delivering up to 20 MIPS throughput at 20 MHz
• Integrated 4-channel 10-bit Analog-to-Digital Converter with internal reference
• Supports in-system programming via SPI serial interface
• Includes debugWIRE on-chip debug system for development

Applications

• Battery-powered embedded systems requiring low power consumption
• Simple sensor interfaces utilizing the integrated ADC
• Basic control loops using the 8-bit Timer/Counter and PWM channels
• Cost-sensitive applications needing compact 8-pin SOIC packaging

Procurement Notes

Verify the specific suffix 'SFR' corresponds to the required tape-and-reel packaging configuration. Confirm that the industrial temperature grade and RoHS compliance meet project specifications. Ensure the ordering part number matches the exact speed grade and package dimensions defined in the Microchip datasheet to avoid compatibility issues.

Selection Notes

Select this component when a compact 8-bit MCU with minimal I/O requirements is needed. It is suitable for designs prioritizing low active current and deep sleep modes. Consider the limited 1KB Flash if complex algorithms are required. Verify that the 6 available I/O lines suffice for the target application's peripheral connections.

Part Context

This part belongs to the ATtiny13A family within the AVR microcontroller portfolio. It shares core architectural features with other variants in the series but differs in package type and storage medium configuration. The SFR suffix specifically denotes the surface-mount SOIC package variant intended for automated assembly processes.

Replacement Considerations

Direct pin-compatible replacements include ATTINY13A-SSU or ATTINY13A-SH, provided the package width and lead pitch match the PCB footprint. Verify that any substitute maintains the same 8-SOIC form factor and electrical characteristics.
