Overview
The AVR32DA32-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 1.8V to 5.5V. The device includes a 12-bit ADC, three analog comparators, a Peripheral Touch Controller (PTC), two Zero-Cross Detectors (ZCD), a DAC, six USARTs, two SPIs, and TWI interfaces. It is housed in a TQFP-32 package and supports an extended temperature range of -40°C to +125°C.
Feature Summary
- Supports vertical migration without code modification across the AVR DA(S) family due to full pin and feature compatibility.
- Includes Program and Debug Interface Disable (PDID) for secure firmware upgrades and authentication.
- Features a Peripheral Touch Controller (PTC) with Driven Shield+ and Boost Mode technologies for capacitive touch applications.
Applications
- Secure firmware upgrade implementations requiring PDID protection
- Capacitive touch interface designs using PTC technology
- Power control systems utilizing ZCD and TCD peripherals
Procurement Notes
Verify the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) as specified in the datasheet. Ensure the package style 'PT' corresponds to the TQFP-32 form factor required for your PCB layout. Cross-reference the specific revision level DS40002228C for any errata or design guidelines relevant to production.
Selection Notes
Select this component when an extended industrial temperature range up to +125°C is required compared to the standard -40°C to +85°C variant. It provides the same peripheral set as the industrial version but is optimized for higher thermal environments. Consider the TQFP-32 package constraints and verify power supply stability within the 1.8V to 5.5V operating window.
Part Context
This part belongs to the AVR32DA28/32/48(S) series within the broader AVR DA(S) family. It shares architectural similarities with other devices in the family, allowing for horizontal migration to reduce pin counts or vertical migration to increase memory and I/O options while maintaining software compatibility.
Replacement Considerations
AVR32DA32-I/PT serves as the industrial temperature rated alternative. Verify that the reduced temperature range of -40°C to +85°C meets your application requirements before substituting.
