ATTINY13A-PU

Overview

The ATTINY13A-PU is an 8-bit AVR microcontroller featuring a high-performance, low-power CMOS architecture. It integrates 1K bytes of In-System Programmable Flash, 64 bytes of EEPROM, and 64 bytes of SRAM. The device supports a maximum clock frequency of 20 MHz with a supply voltage range of 1.8V to 5.5V. Key peripherals include a 4-channel 10-bit ADC, an 8-bit Timer/Counter with PWM, an analog comparator, and a programmable watchdog timer. It utilizes the debugWIRE system for on-chip debugging and offers industrial temperature range operation.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for up to 20 MIPS throughput at 20 MHz
• Non-volatile memory segments with high endurance ratings for Flash and EEPROM data retention
• Integrated peripheral suite including multi-channel ADC, analog comparator, and dual PWM channels
• Support for multiple low-power sleep modes to optimize energy consumption versus processing speed

Applications

• Embedded control systems requiring low power consumption
• Battery-operated devices utilizing picoPower technology
• Industrial applications operating within extended temperature ranges
• Simple sensor interfaces leveraging internal ADC and comparators

Procurement Notes

Verify the specific ordering suffix corresponds to the PDIP package type required for your design. Confirm that the speed grade matches your target operating voltage and frequency requirements. Ensure compatibility with existing development tools supporting the AVR architecture and debugWIRE interface. Check for any recent product change notifications regarding packaging or manufacturing sites.

Selection Notes

Select this component when a compact 8-bit solution with sufficient I/O lines and basic analog capabilities is needed. Consider the trade-off between processing speed and power consumption based on the available sleep modes. Evaluate the need for in-system programming capabilities via SPI. Assess whether the limited SRAM size meets the stack and variable storage requirements of the application software.

Part Context

This part belongs to the ATtinyAVR family, designed for cost-sensitive and space-constrained embedded applications. It shares architectural similarities with other members of the series but differs in memory sizes and package options. The device is manufactured using Microchip's high-density non-volatile memory technology, ensuring reliability and long-term data retention for commercial and industrial environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the ATtiny13 family, such as variants with different speed grades or temperature ranges. Verify if older revisions like the ATtiny13 require firmware adjustments due to errata differences. Ensure substitute parts maintain the same package dimensions and electrical characteristics for seamless integration.
