ATTINY828-AUR

Overview

The ATTINY828-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, dual timer/counters, USART, SPI, and TWI interfaces. It is housed in a 32-TQFP package.

Feature Summary

• Advanced RISC architecture delivering up to 20 MIPS throughput at 20 MHz
• Integrated analog features including a 10-bit ADC and on-chip analog comparator
• Multiple power-saving modes: Idle, ADC Noise Reduction, and Power-down
• Supports in-system programming via ISP and debugWire interface

Applications

• Sensor nodes requiring low power consumption
• Battery-powered embedded systems
• Industrial control applications
• Smart home devices

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 32-TQFP variant. Confirm that the selected revision matches project requirements for memory size and peripheral availability.

Selection Notes

Select this component when high pin count and extensive analog capabilities are required within a compact 8-bit MCU form factor. Consider the ATtiny828R-AUR if tape-and-reel packaging is preferred over trays. Evaluate power consumption profiles across different operating voltages and clock frequencies to optimize battery life.

Part Context

The ATTINY828 belongs to the ATtiny family of 8-bit AVR microcontrollers. It is designed for cost-sensitive applications needing robust performance and rich peripheral sets. The device leverages Atmel's high-density non-volatile memory technology for reliable data retention.

Replacement Considerations

Check for direct substitutes like the ATTINY828R-AU or ATTINY828-AU based on packaging preferences. Verify pin compatibility and software register mapping before swapping packages.
