ATTINY28V-1PI

Overview

The ATTINY28V-1PI is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features 2K bytes of Flash program memory and operates at a maximum clock frequency of 1.2 MHz. The device supports a supply voltage range of 1.8V to 5.5V and includes 11 programmable I/O lines. It is housed in a 28-lead Plastic Dual Inline Package (PDIP) and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Utilizes high-performance AVR RISC architecture with single-cycle instruction execution
• Includes built-in high-current LED driver with programmable modulation capabilities
• Features interrupt and wake-up functionality triggered by low-level input signals
• Integrates an internal calibrated RC oscillator and programmable watchdog timer

Applications

• Embedded control systems requiring low-power operation
• Applications utilizing the integrated high-current LED driver
• Industrial environments necessitating wide temperature tolerance

Procurement Notes

Verify the specific ordering code ATTINY28V-1PI against official manufacturer documentation to confirm package type and speed grade. Ensure compatibility with the required industrial temperature range (-40°C to +85°C). Confirm that the 28-lead PDIP package aligns with your PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when a cost-effective 8-bit solution with integrated LED driving is required. The ATTINY28V-1PI is suitable for designs needing 2K bytes of Flash and 11 I/O lines within a 28-pin DIP footprint. Consider its 1.2 MHz speed limit and 1.8V minimum operating voltage during system power budgeting.

Part Context

This part belongs to the ATtiny28 family, which combines an enhanced RISC 8-bit CPU with nonvolatile Flash memory on a monolithic chip. The V suffix indicates a 1.8V minimum operating voltage capability, distinguishing it from the L variant. The 1PI suffix specifies the 1.2 MHz speed grade and the 28-lead PDIP package configuration.
