ATTINY13-20PU

Overview

The ATTINY13-20PU is an 8-bit AVR microcontroller featuring a high-performance RISC architecture with up to 20 MIPS throughput at 20 MHz. It includes 1K bytes of In-System Programmable Flash, 64 bytes EEPROM, and 64 bytes SRAM. The device operates within a voltage range of 2.7V to 5.5V and supports industrial temperature ranges. Key peripherals include a 4-channel 10-bit ADC, an 8-bit Timer/Counter with PWM, and SPI programming capability.

Feature Summary

• Advanced RISC core executing most instructions in a single clock cycle for efficient processing.
• Non-volatile memory segments offering high endurance for Flash and EEPROM data retention.
• Integrated peripheral suite including analog-to-digital conversion and programmable watchdog timer.
• Supports low-power operation through multiple selectable sleep modes.

Applications

• Embedded control systems requiring compact form factors
• Battery-powered devices utilizing picoPower technology
• Simple sensor interfaces leveraging the integrated ADC

Procurement Notes

Verify the specific speed grade suffix against the required operating frequency and voltage conditions. Confirm package type matches the PCB footprint requirements. Check current availability status as older revisions may be discontinued. Ensure compliance with RoHS standards if applicable to the manufacturing process.

Selection Notes

Select this component when a minimal pin count is necessary alongside basic I/O and analog capabilities. Consider the ATtiny13V variant if operation below 2.7V is required. Evaluate the trade-off between the limited 1KB program memory and the cost benefits of the PDIP package for prototyping or low-volume production.

Part Context

This part belongs to the Microchip ATtiny family, designed for applications needing small code size and low power consumption. It utilizes the AVR enhanced RISC architecture, distinguishing itself from larger AVRs by its reduced peripheral set and memory capacity while maintaining compatibility with standard development tools.

Replacement Considerations

Direct substitutes include other ATtiny13 variants such as ATTINY13-20SU or ATTINY13A-20PU, provided the package and speed grade align with design constraints. Cross-referencing datasheets is essential to verify pinout compatibility and electrical specifications.
