ATTINY48-AUR

Overview

The ATTINY48-AUR is an 8-bit AVR microcontroller featuring 4K bytes of In-System Programmable Flash, 64 bytes of EEPROM, and 256 bytes of SRAM. It operates at frequencies up to 12 MHz within a voltage range of 1.8V to 5.5V. The device includes a 10-bit ADC, two Timer/Counters, SPI, and I2C interfaces. It utilizes a 32-pad QFN package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

Advanced RISC architecture with single-cycle execution for high throughput
In-system programmable non-volatile memory segments
Integrated analog-to-digital converter and on-chip debug system
Multiple software-selectable power-saving sleep modes

Applications

Embedded control systems requiring low power consumption
Industrial monitoring applications with serial communication needs
Battery-powered devices utilizing efficient sleep modes

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-pad QFN configuration. Confirm that the selected revision matches the required datasheet specifications for your design constraints.

Selection Notes

Select this component when a balance of processing speed and memory capacity is required for 8-bit AVR applications. Consider the ATtiny48 over the ATtiny88 if program storage requirements do not exceed 4K bytes. Evaluate the 32-lead package options if additional I/O lines are necessary compared to the 28-pin variants.

Part Context

This part belongs to the ATtiny48/88 family of microcontrollers manufactured by Microchip Technology. It shares architectural similarities with other AVR devices but offers specific memory configurations tailored for cost-sensitive embedded designs. The AUR suffix indicates a specific reel packaging format suitable for automated assembly processes.
