ATTINY13-20PI

Overview

The ATTINY13-20PI is an 8-bit AVR microcontroller manufactured by Microchip Technology, utilizing the ATtiny13 architecture. It features a 1K byte In-System Programmable Flash memory, 64 bytes EEPROM, and 64 bytes SRAM. The device operates at a maximum clock frequency of 20 MHz with a supply voltage range of 2.7V to 5.5V. It is housed in an 8-pin PDIP package and supports industrial temperature ranges.

Feature Summary

• Advanced RISC Architecture with single-cycle execution for up to 20 MIPS throughput
• Integrated peripherals including a 4-channel 10-bit ADC and 8-bit Timer/Counter with PWM
• On-chip debug system (debugWIRE) and SPI-based In-System Programming capability
• Low power consumption with multiple selectable sleep modes

Applications

• Embedded control systems requiring compact form factors
• Battery-powered devices utilizing low-power operational modes
• Simple sensor interfaces leveraging the integrated ADC
• General-purpose logic replacement in space-constrained designs

Procurement Notes

Verify the specific ordering suffix 'PI' against official Microchip documentation, as standard datasheets typically list 'PU' for PDIP packages. Confirm current availability status, as this component may be subject to lifecycle changes or obsolescence. Ensure compatibility with existing PCB footprints and programming interfaces before procurement.

Selection Notes

Select this component for applications requiring minimal I/O count and basic analog-to-digital conversion capabilities within a small footprint. Consider the 20 MHz speed grade relative to the required operating voltage range. Evaluate if the limited memory resources suffice for the intended firmware complexity compared to larger ATtiny variants.

Part Context

This part belongs to the Microchip ATtiny13 family of 8-bit CMOS microcontrollers. It shares core architectural similarities with other members like the ATTINY13A but differs in specific electrical characteristics and feature sets defined by the base model designation. The series is designed for cost-sensitive, low-performance embedded tasks.

Replacement Considerations

Direct pin-compatible replacements include other ATtiny13 variants such as ATTINY13-20PU for PDIP packaging. Verify that substitute parts match the required speed grade and voltage specifications. Cross-reference fuse settings and memory sizes to ensure functional equivalence.
