AVR128DA48-I/6LX

Overview

The AVR128DA48-I/6LX is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 128 KB of Flash memory, 16 KB of SRAM, and 512 B of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an industrial temperature range of -40°C to +85°C. It utilizes a 48-pin VQFN package (suffix 6LX) and provides up to 41 general-purpose I/O pins.

Feature Summary

• Integrates intelligent analog features including a 12-bit differential ADC, DAC, and analog comparators for high-precision signal conditioning.
• Supports capacitive touch applications via the Peripheral Touch Controller (PTC) with Driven Shield+ technology.
• Enables low-latency inter-peripheral communication through the Event System and Configurable Custom Logic (CCL).
• Features a single-pin Unified Program and Debug Interface (UPDI) for simplified programming and debugging workflows.

Applications

• Wired and wireless communication stack implementations requiring high memory density.
• Industrial control systems utilizing smart analog peripherals and real-time processing.
• IoT devices and sensor nodes requiring low-power operation and capacitive touch interfaces.
• Power control applications optimized by the dedicated Timer/Counter type D peripheral.

Procurement Notes

Verify that the ordering suffix 'I' corresponds to the required industrial temperature range (-40°C to +85°C) and '6LX' matches the specific 48-pin VQFN package dimensions. Confirm that the datasheet revision aligns with the manufacturing lot. Ensure compatibility with the target PCB footprint for the VQFN form factor before finalizing procurement orders.

Selection Notes

Select this component when vertical migration within the AVR DA family is required without code modification. Choose this part over smaller pin-count variants if the application demands up to 41 I/O pins and access to advanced peripherals like multiple USARTs or the full PTC channel count. Consider the extended temperature option only if operating conditions exceed standard industrial limits.

Part Context

This device belongs to the AVR128DA28/32/48/64 series, designed for flexible migration across pin counts while maintaining feature compatibility. The 48-pin variant offers a balance between peripheral availability and package size, suitable for designs needing extensive I/O without moving to larger footprints. It serves as a modern replacement for legacy AVR architectures in performance-critical embedded applications.
