AVR32DA48T-I/6LX

Overview

The AVR32DA48T-I/6LX is an 8-bit microcontroller from the AVR DA family, featuring a 48-pin VQFN package. It includes 32 KB of Flash memory, 4 KB of SRAM, and 512 B of EEPROM. The device operates at a maximum frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. Key peripherals include a 12-bit ADC with 18 channels, three analog comparators, one DAC, two zero-cross detectors, five USARTs, two SPI interfaces, and two TWI interfaces. It supports up to 41 programmable I/O pins.

Feature Summary

• Features a flexible low-power architecture with an Event System for CPU-independent inter-peripheral signaling.
• Includes intelligent analog features such as a 12-bit differential ADC, analog comparators with window compare functions, and a Peripheral Touch Controller.
• Provides advanced digital peripherals including Configurable Custom Logic (CCL) and multiple timer/counters optimized for power control and PWM generation.
• Supports secure firmware upgrades through Program and Debug Interface Disable (PDID) mechanisms.

Applications

• Industrial control systems requiring robust peripheral integration
• Smart home appliances utilizing capacitive touch interfaces
• Power management applications using zero-cross detection
• General-purpose embedded controllers in compact form factors

Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape and reel packaging and '6LX' indicates the VQFN48 package style. Confirm the 'I' suffix denotes the industrial temperature range of -40°C to +85°C. Ensure compatibility with the specific pinout and memory configuration defined in the official datasheet DS40002228C before procurement.

Selection Notes

Select this component when a 48-pin footprint is required with high peripheral density. It offers vertical migration compatibility within the AVR DA(S) family without code modification. Consider the 24 MHz operating speed and 1.8 V to 5.5 V supply range for diverse power environments. Evaluate the need for PDID security features if firmware protection is critical.

Part Context

This part belongs to the AVR32DA28/32/48(S) series, which shares architectural similarities with other devices in the AVR DA(S) family. It provides horizontal migration options to lower pin counts or vertical migration to higher memory variants like the AVR64DA or AVR128DA series while maintaining pin and feature compatibility.

Replacement Considerations

Direct substitutes within the same package and feature set are not explicitly listed in the provided documentation. Vertical migration to AVR64DA48 or AVR128DA48 variants is supported without code modification, though memory sizes differ. Horizontal migration to AVR32DA32 or AVR32DA28 reduces available I/O and peripheral count.
