AVR32DA48T-E/PT

Overview

The AVR32DA48T-E/PT is an 8-bit microcontroller from the AVR DA family, featuring a 32 KB Flash memory, 4 KB SRAM, and 512B EEPROM. It operates at a maximum frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC with 18 channels, three analog comparators, two zero-cross detectors, a DAC, and a Peripheral Touch Controller (PTC). It offers up to 41 programmable I/O pins in 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 detection
• General-purpose embedded control requiring secure firmware upgrades via PDID

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and 'T' indicates tape and reel packaging. Confirm the specific datasheet DS40002228 applies to this part number variant. Ensure the application environment supports the specified 1.8V to 5.5V operating voltage range.

Selection Notes

Select this component when 32 KB of Flash and 4 KB of SRAM are sufficient for the application logic. Choose the AVR32DA48T-E/PT over other pin counts if 48 pins and 41 I/O lines are required. Consider the extended temperature rating if operation above 85°C is necessary.

Part Context

This part belongs to the AVR DA(S) family, which utilizes the latest Microchip technologies for low-power and flexible architecture. It shares the same core CPU and peripheral set as the AVR64DA and AVR128DA series, differing primarily in memory size and pin availability within the same package footprint.

Replacement Considerations

AVR32DA48-I/PT serves as a direct substitute with identical functionality but a lower industrial temperature rating (-40°C to +85°C).
