ATTINY28V-1PU

Overview

The ATTINY28V-1PU is an 8-bit AVR microcontroller from Microchip Technology, featuring a PDIP-28 package. It operates within a voltage range of 1.8 V to 5.5 V and supports a maximum clock frequency of 1.2 MHz. The device includes 2 kB of Flash program memory and provides 11 I/O lines. It contains two timer/counters and lacks an ADC. Operating temperatures span from -40°C to +85°C.

Feature Summary

AVR RISC core architecture with single-cycle instruction execution
System-in-programmable Flash memory for code storage
Integrated debugWIRE interface for on-chip debugging
picoPower technology for low-power operation modes

Applications

Embedded control systems requiring low pin count
Battery-powered devices utilizing low-voltage operation
Simple peripheral interfacing via SPI or TWI
General-purpose logic control in industrial environments

Procurement Notes

Verify component authenticity through authorized distributors as the part is marked obsolete. Confirm package integrity upon receipt, noting the PDIP-28 form factor. Check RoHS compliance documentation for environmental standards. Ensure handling procedures account for static sensitivity during installation. Validate supplier credentials to avoid counterfeit components in the supply chain.

Selection Notes

Select this component for applications needing minimal I/O with robust AVR compatibility. Consider the PDIP-28 package for through-hole assembly requirements. Evaluate power consumption against picoPower capabilities for battery life. Verify that 2 kB Flash suffices for application firmware size. Ensure voltage levels align with the 1.8 V to 5.5 V operating range.

Part Context

This device belongs to the ATtiny family of 8-bit microcontrollers designed by Atmel, now Microchip Technology. It utilizes the AVR architecture optimized for efficiency. The series targets cost-sensitive embedded applications. Development tools like Atmel Studio support programming and debugging. The component represents a legacy option in modern low-pin-count MCU selections.
