AVR64DA32-E/PT

Overview

The AVR64DA32-E/PT is a 32-pin microcontroller from the AVR DA family, featuring an AVR CPU with hardware multiplier running at up to 24 MHz. It includes 64 KB of Flash memory, 8 KB of SRAM, and 512 B of EEPROM. The device supports a supply voltage range of 1.8 V to 5.5 V and operates within an extended temperature range of -40°C to +125°C. Key peripherals include a 12-bit ADC, three analog comparators, a 10-bit DAC, and a Peripheral Touch Controller.

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, three analog comparators, and a 10-bit DAC.
• Includes a Peripheral Touch Controller (PTC) with Driven Shield+ and Boost Mode technologies for capacitive touch applications.
• Features a single-pin Unified Program and Debug Interface (UPDI) for programming and debugging.

Applications

• Capacitive touch button, slider, wheel, and 2D surface interfaces
• Power control systems utilizing Timer/Counter type D
• Industrial communication networks using USART, SPI, and TWI/I2C
• Low-power embedded applications requiring multiple sleep modes

Procurement Notes

Verify the specific ordering suffix '-E' confirms the extended temperature range (-40°C to +125°C) as defined in the datasheet designation table. Confirm the package style 'PT' corresponds to the TQFP form factor. Ensure the part number matches the exact memory configuration of 64 KB Flash and 8 KB SRAM for the 32-pin variant.

Selection Notes

Select this component when an extended industrial temperature range is required alongside the standard AVR DA peripheral set. The 32-pin package offers a balance between I/O count and physical footprint. Consider the 1.8V to 5.5V supply range for flexible power design options compared to lower-voltage-only alternatives.

Part Context
