AVR32DA48-E/PT

Overview

The AVR32DA48-E/PT is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 32 KB of Flash memory, 4 KB of SRAM, and 512 B of EEPROM. The device operates within a voltage range of 1.8 V to 5.5 V and supports an extended temperature range of -40°C to +125°C. Key peripherals include a 12-bit ADC, three analog comparators, a DAC, two zero-cross detectors, and a Peripheral Touch Controller. It utilizes a TQFP-48 package.

Feature Summary

• Supports vertical migration without code modification across the AVR DA(S) family due to full pin and feature compatibility.
• Integrates intelligent analog features including a 12-bit differential ADC, analog comparators, and a Peripheral Touch Controller for capacitive touch applications.
• Provides advanced digital peripherals such as Configurable Custom Logic (CCL), Event System, and multiple communication interfaces like USART, SPI, and TWI.

Applications

• Capacitive touch interface designs using buttons, sliders, or wheels
• Power control systems utilizing Timer/Counter type D and zero-cross detectors
• Secure firmware upgrade implementations requiring Program and Debug Interface Disable (PDID)
• Industrial automation controllers operating in extended temperature environments

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) rather than the industrial range. Confirm the package style 'PT' matches the required TQFP form factor. Ensure the specific part number aligns with the 32 KB Flash variant within the AVR32DA48 series. Cross-reference the datasheet revision to confirm peripheral availability.

Selection Notes

Select this component when extended temperature operation up to 125°C is required alongside standard AVR DA family features. It offers a balance of processing speed at 24 MHz and sufficient memory for moderate complexity applications. Consider the Peripheral Touch Controller if capacitive sensing is needed, or utilize the CCL for custom logic implementation without additional external components.

Part Context

This device belongs to the AVR DA(S) family, which shares architectural similarities with the AVR EA and DB families but introduces specific enhancements like the Peripheral Touch Controller and updated clock options. It serves as a general-purpose microcontroller suitable for applications requiring robust I/O capabilities and flexible analog integration within a compact footprint.

Replacement Considerations

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