Overview

The ATTINY13-20SI is an 8-bit AVR microcontroller from Microchip Technology, featuring a high-performance RISC core with up to 20 MIPS throughput at 20 MHz. It includes 1 KB of In-System Programmable Flash, 64 bytes of EEPROM, and 64 bytes of SRAM. The device supports a supply voltage range of 2.7V to 5.5V and operates within the industrial temperature range of -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 on-chip debugging.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for efficient processing.
• Integrated non-volatile memory segments with high endurance for program storage and data retention.
• On-chip debugging system (debugWIRE) and SPI-based in-system programming capabilities.
• Multiple low-power operating modes including Idle, ADC Noise Reduction, and Power-down.

Applications

• Industrial control systems requiring robust performance across wide temperature ranges.
• Battery-powered devices utilizing picoPower technology for extended operational life.
• Embedded sensor interfaces leveraging the integrated 10-bit ADC and analog comparator.
• Cost-sensitive applications needing compact 8-pin or 20-pad package solutions.

Procurement Notes

Verify the specific ordering suffix 'SI' against official Microchip documentation, as standard listings typically utilize suffixes like PU, SU, MU, or MMU. Confirm current production status, as ATtiny13 variants may be subject to lifecycle changes. Ensure compatibility with existing PCB footprints for the selected package type before procurement.

Selection Notes

Select this component when a balance of processing speed and power efficiency is required for small form-factor designs. Consider the 20 MHz speed grade for applications demanding higher instruction throughput compared to lower-speed variants. Evaluate package availability based on assembly requirements, choosing between through-hole or surface-mount options as needed.

Part Context

This device belongs to the ATtiny13 family of 8-bit AVR microcontrollers, designed for low-cost, high-performance embedded applications. It shares architectural similarities with other members of the ATtiny series but offers specific memory sizes and peripheral configurations tailored for compact systems. The product line emphasizes energy efficiency without compromising computational capability.

Replacement Considerations

Direct substitutes include ATTINY13-20PU, ATTINY13-20SU, ATTINY13-20MU, and ATTINY13-20MMU, which share identical electrical characteristics and pinouts. Verify package compatibility when substituting between PDIP, SOIC, and MLF formats.
