ATTINY828R-AUR

Overview

The ATTINY828R-AUR is an 8-bit AVR microcontroller featuring 8KB of in-system programmable Flash, 512 bytes of SRAM, and 256 bytes of EEPROM. It operates at speeds up to 20 MHz with a supply voltage range of 1.7V to 5.5V. The device includes 28 programmable I/O lines, a 10-bit ADC with 32 channels, and interfaces such as USART, SPI, and TWI. It is housed in a 32-TQFP package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput.
• Integrated non-volatile memory with optional boot code section and independent lock bits.
• Supports multiple low-power modes including Idle, ADC Noise Reduction, and Power-down.
• Features calibrated internal oscillators and high-current drive capability on select I/O pins.

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control applications utilizing the analog comparator and ADC
• Communication devices using USART or SPI interfaces

Procurement Notes

Verify the specific suffix 'AUR' corresponds to the Tape and Reel packaging format when ordering. Confirm that the speed grade matches the required operating voltage and frequency constraints for your design. Ensure the 32-TQFP footprint aligns with your PCB layout specifications before finalizing procurement.

Selection Notes

Select this component if your application requires a balance of moderate Flash memory capacity and extensive I/O connectivity. The wide voltage range supports both 1.8V and 5V logic systems. Consider the pin count and peripheral set against larger ATtiny variants if additional resources are needed.

Part Context

This part belongs to the ATtiny828 family within Microchip's AVR portfolio. It shares architectural similarities with other 8-bit AVR controllers but offers specific memory sizes and peripheral configurations tailored for cost-sensitive, space-constrained designs.

Replacement Considerations

Check datasheet compatibility for ATTINY828R-AU (Tray) if reel packaging is not strictly required. Verify electrical characteristics against ATTINY84V-10MUR for lower pin count alternatives.
