AVR32DA48-E/6LX

Overview

The AVR32DA48-E/6LX is an 8-bit microcontroller from the AVR DA family, featuring a CPU with hardware multiplier running at up to 24 MHz. It includes 32 KB of Flash memory, 4 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 industrial (-40°C to +85°C) and extended (-40°C to +125°C) temperature ranges. It utilizes a 48-pin VQFN package (6x6 mm). Key peripherals include two TCA timers, four TCB timers, one TCD timer, five USARTs, two SPI interfaces, two TWI/I2C interfaces, a 12-bit ADC, a 10-bit DAC, three analog comparators, and a Peripheral Touch Controller.

Feature Summary

• Supports Program and Debug Interface Disable (PDID) for secure firmware upgrades and authentication.
• Integrates an Event System for CPU-independent inter-peripheral signaling.
• Includes Configurable Custom Logic (CCL) with programmable Look-up Tables.
• Features a Peripheral Touch Controller (PTC) with Driven Shield+ technology.

Applications

• Smart energy applications such as thermostats and power meters
• Home appliances including coffee makers and stoves
• Consumer electronics and office equipment
• Industrial control systems requiring low-power operation

Procurement Notes

Verify the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and '6LX' specifies the VQFN-48 package. Confirm that the specific part number corresponds to the standard version without PDID unless explicitly required, as PDID is typically reserved for AVR DAS devices. Ensure compatibility with existing designs when migrating from other AVR families.

Selection Notes

Select this component for applications requiring vertical migration within the AVR DA(S) family without code modification. Consider the 24 MHz maximum frequency and 32 KB Flash capacity against project requirements. Evaluate the need for the extended temperature range indicated by the 'E' suffix. Compare peripheral counts, such as the number of USARTs and ADC channels, with alternative pin counts in the same family.

Part Context

This device belongs to the AVR DA(S) family, which shares architectural similarities with the AVR EA series but offers enhanced features like higher clock speeds and additional peripherals. It is designed for low-power applications and supports seamless migration between different flash sizes and pin counts within the family.

Replacement Considerations

AVR32DA48-I/6LX: Identical specifications except for the industrial temperature range (-40°C to +85°C).
